SSM权限管理系统
项目搭建
1.创建Maven-webapp工程
2.SSM框架集成
2.1添加依赖，即pom.xml文件

创建员工表sql语句
CREATE TABLE `employee` (
`id` bigint(20) NOT NULL,
`username` varchar(50) DEFAULT NULL,
`password` varchar(100) DEFAULT NULL,
`realname` varchar(50) DEFAULT NULL,
`tel` varchar(50) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`inputtime` datetime DEFAULT NULL,
`state` tinyint(1) DEFAULT NULL,
`admin` tinyint(1) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
生成员工mapper，双击maven插件
主页搭建
EasyUI主页
1.在目录当中引入EasyUI相关JS与css
2.在首页当中引入所需要的js与css
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/static/plugins/easyui/uimaker/easyui.css">
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/static/plugins/easyui/uimaker/icon.css">
<script type="text/javascript" src="${pageContext.request.contextPath}/static/plugins/easyui/jquery.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/static/plugins/easyui/jquery.easyui.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/static/plugins/easyui/easyui-lang-zh_CN.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/static/js/index.js"></script>
3.编写body首页框架格式
<body class="easyui-layout">
<div data-options="region:'north'" style="height:100px; background: #ec4e00; padding: 20px 20px">
<img src="main_logo.png" alt="">
</div>
<div data-options="region:'south'" style="height:50px; border-bottom: 3px solid #ec4e00">
<p align="center" style="font-size: 14px">撩课学院</p>
</div>
<div data-options="region:'west',split:true" style="width:300px;">
<div id="aa" class="easyui-accordion" data-options="fit:true">
<div title="菜单" data-options="iconCls:'icon-save',selected:true" style="overflow:auto;padding:10px;">
<!--tree-->
<ul id="tree"></ul>
</div>
<div title="公告" data-options="iconCls:'icon-reload'" style="padding:10px;">
</div>
</div>
</div>
<div data-options="region:'center'" style="background:#eee;">
<!--标签-->
<div id="tabs" style="overflow: hidden" >
</div>
</div>
</body>
4.创建首页index.js引入
$(function () {
$("#tabs").tabs({
fit:true
})
$('#tree').tree({
url:'/getTreeData',
lines:true,
onSelect: function(node){
/*在添加之前, 做判断 判断这个标签是否存在 */
var exists = $("#tabs").tabs("exists",node.text);
if(exists){
/*存在,就让它选中*/
$("#tabs").tabs("select",node.text);
}else {
if (node.url !=''&& node.url !=null){
/*如果不存在 ,添加新标签*/
$("#tabs").tabs("add",{
title:node.text,
/*href:node.attributes.url,*/ /*href 引入的是body当中*/
content:"<iframe src="+node.url+" frameborder='0' width='100%' height='100%'></iframe>",
closable:true
})
}
}
},
onLoadSuccess: function (node, data) {
console.log(data[0].children[0].id);
if (data.length > 0) {
//找到第一个元素
var n = $('#tree').tree('find', data[0].children[0].id);
//调用选中事件
$('#tree').tree('select', n.target);
}
}
});
});
员工列表
1.在tree当中指定跳转的地址--暂时用tree.json文件代替
[
{
"id": 1,
"text": "系统管理",
"children": [
{
"id":2,
"text": "员工管理",
"url": "/employee"
},
{
"id":3,
"text": "角色权限管理",
"url": "/role"
},
{
"id":4,
"text": "菜单管理",
"url": "/menu"
}
]
}
]
**index.js**
$(function () {
$("#tabs").tabs({
fit:true
})
$('#tree').tree({
url:"static/tree.json",
lines:true,
onSelect: function(node){
/*在添加之前, 做判断 判断这个标签是否存在 */
var exists = $("#tabs").tabs("exists",node.text);
if(exists){
/*存在,就让它选中*/
$("#tabs").tabs("select",node.text);
}else {
if (node.url !=''&& node.url !=null){
/*如果不存在 ,添加新标签*/
$("#tabs").tabs("add",{
title:node.text,
/*href:node.attributes.url,*/ /*href 引入的是body当中*/
content:"<iframe src="+node.url+" frameborder='0' width='100%' height='100%'></iframe>",
closable:true
})
}
}
}
});
});
2.创建页面跳转控制器,接收请求跳转到Employee页面
@Controller
public class PageLocation {
@RequestMapping("/employee")
public String employee(){
return "employee";
}
@RequestMapping("/department")
public String department(){
return "department";
}
}
3.在Employee页面中引入公共的EasyUI相关js编写数据表格
<script type="text/javascript" src="${pageContext.request.contextPath}/static/js/employee.js"></script>
4.创建Employee.js引入设置-数据表格
数据加载
**employee.js**
$(function () {
/*员式数据列表*/
$("#dg").datagrid({
url:"/employeeList",
columns:[[
{field:'username',title:'姓名',width:100,align:'center'},
{field:'inputtime',title:'入职时间',width:100,align:'center'},
{field:'tel',title:'电话',width:100,align:'center'},
{field:'email',title:'邮箱',width:100,align:'center'},
{field:'department',title:'部门',width:100,align:'center',formatter: function(value,row,index){
if (value){
return value.name;
}
}},
{field:'state',title:'状态',width:100,align:'center',formatter: function(value,row,index){
if(row.state){
return "在职";
}else {
return "<font style='color: red'>离职</font>"
}
}},
{field:'admin',title:'管理员',width:100,align:'center',formatter: function(value,row,index){
if(row.admin){
return "是";
}else {
return "否"
}
}},
]],
fit:true,
fitColumns:true,
rownumbers:true,
pagination:true,
singleSelect:true,
striped:true,
toolbar:"#tb",
onClickRow:function (rowIndex,rowData) {
/*判断当前行是否是离职状态*/
if(!rowData.state){
/*离职,把离职按钮禁用*/
$("#delete").linkbutton("disable");
}else {
/*离职,把离职按钮启用*/
$("#delete").linkbutton("enable");
}
}
});
})
控制层
@Controller
public class EmployeeController {
/*注入业务层*/
@Autowired
private EmployeeService employeeService;
@RequestMapping("/employee")
public String employee(){
return "employee";
}
@RequestMapping("/employeeList")
@ResponseBody
public PageListRes employeeList(QueryVo vo){
System.out.println(vo);
/*调用业务层查询员工*/
PageListRes pageListRes = employeeService.getEmployee(vo);
return pageListRes;
}
})
业务层
@Service
@Transactional
public class EmployeeServiceImpl implements EmployeeService {
@Autowired
private EmployeeMapper employeeMapper;
@Override
public PageListRes getEmployee(QueryVo vo) {
/*调用mapper 查询员工 */
Page<Object> page = PageHelper.startPage(vo.getPage(), vo.getRows());
List<Employee> employees = employeeMapper.selectAll(vo);
/*封装成pageList*/
PageListRes pageListRes = new PageListRes();
pageListRes.setTotal(page.getTotal());
pageListRes.setRows(employees);
return pageListRes;
}
})
日期格式化
@JsonFormat(pattern = "yyyy-MM-dd", timezone = "GMT+8")
@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date inputtime;
格式化状态和管理员
5.创建部门表
建表语句
CREATE TABLE `department` (
`id` bigint(20) NOT NULL,
`name` varchar(10) DEFAULT NULL COMMENT '部门名称 ',
`sn` varchar(20) DEFAULT NULL COMMENT '部门编号',
`manager_id` bigint(20) DEFAULT NULL,
`parent_id` bigint(20) DEFAULT NULL,
`state` tinyint(1) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `manager_id` (`manager_id`),
KEY `parent_id` (`parent_id`),
CONSTRAINT `department_ibfk_1` FOREIGN KEY (`manager_id`) REFERENCES `employee` (`id`),
CONSTRAINT `department_ibfk_2` FOREIGN KEY (`parent_id`) REFERENCES `department` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
employee表添加字段dept_id
在代码生成器当中生成相关domain和mapper
修改employee的domian
@Setter@Getter@ToString
public class Employee {
private Long id;
private String username;
private String password;
@JsonFormat(pattern = "yyyy-MM-dd", timezone = "GMT+8")
@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date inputtime;
private String tel;
private String email;
private Boolean state;
private Boolean admin;
private Department department;
}
6.查询部门
EmployeeMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.itlike.mapper.EmployeeMapper" >
<resultMap id="BaseResultMap" type="com.itlike.domain.Employee" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="username" property="username" jdbcType="VARCHAR" />
<result column="inputtime" property="inputtime" jdbcType="TIMESTAMP" />
<result column="tel" property="tel" jdbcType="VARCHAR" />
<result column="email" property="email" jdbcType="VARCHAR" />
<result column="state" property="state" jdbcType="BIT" />
<result column="admin" property="admin" jdbcType="BIT" />
<association property="department" javaType="com.itlike.domain.Department" columnPrefix="d_">
<result property="id" column="id"/>
<result property="name" column="name"/>
</association>
</resultMap>
<!--员工关联部门查询-->
<select id="selectAll" resultMap="BaseResultMap" >
select
e.id,
e.username,
e.inputtime,
e.tel,
e.email,
e.state,
e.admin,
d.id as d_id,
d.`name` as d_name
from employee as e
LEFT JOIN department as d
ON e.dep_id = d.id
<include refid="where_sql"/>
order by e.id desc
</select>
</mapper>
$(function () {
/*员式数据列表*/
$("#dg").datagrid({
url:"/employeeList",
columns:[[
{field:'username',title:'姓名',width:100,align:'center'},
{field:'inputtime',title:'入职时间',width:100,align:'center'},
{field:'tel',title:'电话',width:100,align:'center'},
{field:'email',title:'邮箱',width:100,align:'center'},
{field:'department',title:'部门',width:100,align:'center',formatter: function(value,row,index){
if (value){
return value.name;
}
}},
{field:'state',title:'状态',width:100,align:'center',formatter: function(value,row,index){
if(row.state){
return "在职";
}else {
return "<font style='color: red'>离职</font>"
}
}},
{field:'admin',title:'管理员',width:100,align:'center',formatter: function(value,row,index){
if(row.admin){
return "是";
}else {
return "否"
}
}},
]]
});
})
7.列表添加工具栏目
1.添加标签
<div id="tb">
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-add',plain:true" id="add">添加</a>
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-edit',plain:true" id="edit">编辑</a>
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-remove',plain:true" id="delete">删除</a>
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-reload',plain:true" id="reload">刷新</a>
</div>
2.处理Js
toolbar: '#tb',
8.添加对话框弹出
对话框标签
<table align="center" style="border-spacing: 0px 10px">
<tr>
<td>用户名:</td>
<td><input type="text" class="easyui-validatebox" data-options="required:true"></td>
</tr>
<tr>
<td>真实姓名:</td>
<td><input type="text" class="easyui-validatebox" data-options="required:true"></td>
</tr>
<tr>
<td>手机:</td>
<td><input type="text" class="easyui-validatebox" data-options="required:true"></td>
</tr>
<tr>
<td>邮箱:</td>
<td><input type="text" class="easyui-validatebox" data-options="required:true,validType:'email'" ></td>
</tr>
<tr>
<td>入职日期:</td>
<td><input type="text" class="easyui-datebox" required="required"></td>
</tr>
<tr>
<td>部门:</td>
<td><select id="department"></select></td>
</tr>
<tr>
<td>是否管理员:</td>
<td><select id="state"></select></td>
</tr>
</table>
部门列表展示
/*部门选择 下拉列表*/
$("#department").combobox({
width:150,
panelHeight:'auto',
editable:false,
url:'departList',
textField:'name',
valueField:'id',
onLoadSuccess:function () { /*数据加载完毕之后回调*/
$("#department").each(function(i){
var span = $(this).siblings("span")[i];
var targetInput = $(span).find("input:first");
if(targetInput){
$(targetInput).attr("placeholder", $(this).attr("placeholder"));
}
});
}
});
设置placehode
$("#department").each(function(i){
var span = $(this).siblings("span")[i];
var targetInput = $(span).find("input:first");
if(targetInput){
$(targetInput).attr("placeholder", $(this).attr("placeholder"));
}
});
是否管理员下拉列表展示
/*管理员下拉列表选择*/
$("#state").combobox({
width:150,
panelHeight:'auto',
textField:'label',
valueField:'value',
data:[{
label:'是',
value:'true'
},{
label:'否',
value:'false'
}]
});
$("#state").combobox({"select","否"});
9.保存
表单标签上填写name
<form id="employeeForm">
<%--添加一个隐藏域 编辑--%>
<input type="hidden" name="id">
<table align="center" style="border-spacing: 0px 10px">
<tr>
<td>用户名:</td>
<td><input type="text" name="username" class="easyui-validatebox" data-options="required:true"></td>
</tr>
<tr id="password">
<td>密码:</td>
<td><input type="text" name="password" class="easyui-validatebox"></td>
</tr>
<tr>
<td>手机:</td>
<td><input type="text" name="tel" class="easyui-validatebox" ></td>
</tr>
<tr>
<td>邮箱:</td>
<td><input type="text" name="email" class="easyui-validatebox" ></td>
</tr>
<tr>
<td>入职日期:</td>
<td><input type="text" name="inputtime" class="easyui-datebox"></td>
</tr>
<tr>
<td>部门:</td>
<td><input id="department" name="department.id" placeholder="请选择部门"/></td>
</tr>
<tr>
<td>是否管理员:</td>
<td><input id="state" name="admin" placeholder="是否为管理员"/></td>
</tr>
<tr>
<td>选择角色:</td>
<td><input id="role" name="role.rid" placeholder="请选择角色"/></td>
</tr>
</table>
</form>
下拉列表设置默认值时, 默认value也要设置上去
保存时判断添加还是编辑
监听保存按钮,提交表单
/*对话框*/
$("#dialog").dialog({
width:350,
height:400,
closed:true,
buttons:[{
text:'保存',
handler:function(){
/*判断当前是添加 还是编辑*/
var id = $("[name='id']").val();
var url;
if(id){
/*编辑*/
url = "updateEmployee";
}else {
/*添加*/
url= "saveEmployee";
}
/*提交表单*/
$("#employeeForm").form("submit",{
url:url,
onSubmit:function(param){
/*获取选中的角色*/
var values = $("#role").combobox("getValues");
for(var i = 0; i < values.length; i++){
var rid = values[i];
param["roles["+i+"].rid"] = rid;
}
},
success:function (data) {
data = $.parseJSON(data);
if (data.success){
$.messager.alert("温馨提示",data.msg);
/*关闭对话框 */
$("#dialog").dialog("close");
/*重新加载数据表格*/
$("#dg").datagrid("reload");
} else {
$.messager.alert("温馨提示",data.msg);
}
}
});
}
},{
text:'关闭',
handler:function(){
$("#dialog").dialog("close");
}
}]
});
10.编辑
监听编辑按钮点击
/*监听编辑按钮点击*/
$("#edit").click(function () {
/*获取当前选中的行*/
var rowData = $("#dg").datagrid("getSelected");
console.log(rowData);
if(!rowData){
$.messager.alert("提示","选择一行数据进行编辑");
return;
}
/*取消密码验证*/
$("[name='password']").validatebox({required:false});
$("#password").hide();
/*弹出对话框*/
$("#dialog").dialog("setTitle","编辑员工");
$("#dialog").dialog("open");
/*回显部门*/
rowData["department.id"] = rowData["department"].id;
/*回显管理员*/
rowData["admin"] = rowData["admin"]+"";
/*回显角色*/
/*根据当前用户的id,查出对应的角色*/
$.get("/getRoleByEid?id="+rowData.id,function (data) {
/*设置下拉列表数据回显*/
$("#role").combobox("setValues",data);
});
/*选中数据的回示*/
$("#employeeForm").form("load",rowData);
});
更新业务逻辑
/*接收更新员工请求*/
@RequestMapping("/updateEmployee")
@ResponseBody
@RequiresPermissions("employee:edit")
public AjaxRes updateEmployee(Employee employee){
AjaxRes ajaxRes = new AjaxRes();
try {
/*调用业务层,更新员工*/
employeeService.updateEmployee(employee);
ajaxRes.setMsg("更新成功");
ajaxRes.setSuccess(true);
}catch (Exception e){
ajaxRes.setSuccess(false);
ajaxRes.setMsg("更新失败");
}
return ajaxRes;
}
11.离职
离职按钮点击
/*设置离职按钮点击*/
$("#delete").click(function () {
/*获取当前选中的行*/
var rowData = $("#dg").datagrid("getSelected");
console.log(rowData);
if(!rowData){
$.messager.alert("提示","选择一行数据进行编辑");
return;
}
/*提醒用户,是否做离职操作*/
$.messager.confirm("确认","是否做离职操作",function (res) {
if(res){
/*做离职操作*/
$.get("/updateState?id="+rowData.id,function (data) {
if (data.success){
$.messager.alert("温馨提示",data.msg);
/*重新加载数据表格*/
$("#dg").datagrid("reload");
} else {
$.messager.alert("温馨提示",data.msg);
}
});
}
});
});
业务处理
/*接收离职操作请求*/
@RequestMapping("/updateState")
@ResponseBody
@RequiresPermissions("employee:delete")
public AjaxRes updateState(Long id){
AjaxRes ajaxRes = new AjaxRes();
try {
/*调用业务层,设置员工离职状态*/
employeeService.updateState(id);
ajaxRes.setMsg("更新成功");
ajaxRes.setSuccess(true);
}catch (Exception e){
System.out.println(e);
ajaxRes.setSuccess(false);
ajaxRes.setMsg("更新失败");
}
return ajaxRes;
}
12.离职按钮禁用
给数据表格绑定选中事件
/*员式数据列表*/
$("#dg").datagrid({
url:"/employeeList",
columns:[[
{field:'username',title:'姓名',width:100,align:'center'},
{field:'inputtime',title:'入职时间',width:100,align:'center'},
{field:'tel',title:'电话',width:100,align:'center'},
{field:'email',title:'邮箱',width:100,align:'center'},
{field:'department',title:'部门',width:100,align:'center',formatter: function(value,row,index){
if (value){
return value.name;
}
}},
{field:'state',title:'状态',width:100,align:'center',formatter: function(value,row,index){
if(row.state){
return "在职";
}else {
return "<font style='color: red'>离职</font>"
}
}},
{field:'admin',title:'管理员',width:100,align:'center',formatter: function(value,row,index){
if(row.admin){
return "是";
}else {
return "否"
}
}},
]],
fit:true,
fitColumns:true,
rownumbers:true,
pagination:true,
singleSelect:true,
striped:true,
toolbar:"#tb",
onClickRow:function (rowIndex,rowData) {
/*判断当前行是否是离职状态*/
if(!rowData.state){
/*离职,把离职按钮禁用*/
$("#delete").linkbutton("disable");
}else {
/*离职,把离职按钮启用*/
$("#delete").linkbutton("enable");
}
}
});
添加按钮js插件（记得是因为EasyUI带有小bug）
base.js
/**
* linkbutton方法扩展
* @param {Object} jq
*/
$.extend($.fn.linkbutton.methods, {
/**
* 激活选项（覆盖重写）
* @param {Object} jq
*/
enable: function(jq){
return jq.each(function(){
var state = $.data(this, 'linkbutton');
if ($(this).hasClass('l-btn-disabled')) {
var itemData = state._eventsStore;
//恢复超链接
if (itemData.href) {
$(this).attr("href", itemData.href);
}
//回复点击事件
if (itemData.onclicks) {
for (var j = 0; j < itemData.onclicks.length; j++) {
$(this).bind('click', itemData.onclicks[j]);
}
}
//设置target为null，清空存储的事件处理程序
itemData.target = null;
itemData.onclicks = [];
$(this).removeClass('l-btn-disabled');
}
});
},
/**
* 禁用选项（覆盖重写）
* @param {Object} jq
*/
disable: function(jq){
return jq.each(function(){
var state = $.data(this, 'linkbutton');
if (!state._eventsStore)
state._eventsStore = {};
if (!$(this).hasClass('l-btn-disabled')) {
var eventsStore = {};
eventsStore.target = this;
eventsStore.onclicks = [];
//处理超链接
var strHref = $(this).attr("href");
if (strHref) {
eventsStore.href = strHref;
$(this).attr("href", "javascript:void(0)");
}
//处理直接耦合绑定到onclick属性上的事件
var onclickStr = $(this).attr("onclick");
if (onclickStr && onclickStr != "") {
eventsStore.onclicks[eventsStore.onclicks.length] = new Function(onclickStr);
$(this).attr("onclick", "");
}
//处理使用jquery绑定的事件
var eventDatas = $(this).data("events") || $._data(this, 'events');
if (eventDatas["click"]) {
var eventData = eventDatas["click"];
for (var i = 0; i < eventData.length; i++) {
if (eventData[i].namespace != "menu") {
eventsStore.onclicks[eventsStore.onclicks.length] = eventData[i]["handler"];
$(this).unbind('click', eventData[i]["handler"]);
i--;
}
}
}
state._eventsStore = eventsStore;
$(this).addClass('l-btn-disabled');
}
});
}
});
13.分页控制
EasyUI中可以自动的提交分页参数直接接收分页参数
@RequestMapping("/employeeList")
@ResponseBody
public PageListRes employeeList(QueryVo vo){
System.out.println(vo);
/*调用业务层查询员工*/
PageListRes pageListRes = employeeService.getEmployee(vo);
return pageListRes;
}
业务处理
@Override
public PageListRes getEmployee(QueryVo vo) {
/*调用mapper 查询员工 */
Page<Object> page = PageHelper.startPage(vo.getPage(), vo.getRows());
List<Employee> employees = employeeMapper.selectAll(vo);
/*封装成pageList*/
PageListRes pageListRes = new PageListRes();
pageListRes.setTotal(page.getTotal());
pageListRes.setRows(employees);
return pageListRes;
}
14.高级查询
在toolbar上添加搜索框
<input type="text" name="keyword" style="width: 200px; height: 30px;padding-left: 5px;">
<a class="easyui-linkbutton" iconCls="icon-search" id="searchbtn">查询</a>
监听搜索点击
/*监听搜索按钮点击*/
$("#searchbtn").click(function () {
/*获取搜索的内容*/
var keyword = $("[name='keyword']").val();
/*重新加载列表 把参数keyword传过去*/
$("#dg").datagrid("load",{keyword:keyword});
});
接收参数处理
@Setter@Getter@ToString
public class QueryVo {
private int page;
private int rows;
private String keyword;
}
@Override
public PageListRes getEmployee(QueryVo vo) {
/*调用mapper 查询员工 */
Page<Object> page = PageHelper.startPage(vo.getPage(), vo.getRows());
List<Employee> employees = employeeMapper.selectAll(vo);
/*封装成pageList*/
PageListRes pageListRes = new PageListRes();
pageListRes.setTotal(page.getTotal());
pageListRes.setRows(employees);
return pageListRes;
}
<sql id="where_sql">
<where>
<if test="keyword !=null and keyword !=''">
and e.username like concat('%',#{keyword},'%')
or e.tel like concat('%',#{keyword},'%')
or e.email like concat('%',#{keyword},'%')
</if>
</where>
</sql>
<!--员工关联部门查询-->
<select id="selectAll" resultMap="BaseResultMap" >
select
e.id,
e.username,
e.inputtime,
e.tel,
e.email,
e.state,
e.admin,
d.id as d_id,
d.`name` as d_name
from employee as e
LEFT JOIN department as d
ON e.dep_id = d.id
<include refid="where_sql"/>
order by e.id desc
</select>
添加权限
1.建立角色与权限的表
为多对多关系
- 角色表
CREATE TABLE `employee` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`username` varchar(50) DEFAULT NULL,
`inputtime` datetime DEFAULT NULL,
`tel` varchar(20) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`state` tinyint(1) DEFAULT NULL,
`admin` tinyint(1) DEFAULT NULL,
`dep_id` bigint(20) DEFAULT NULL,
`password` varchar(50) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `dep_id` (`dep_id`),
CONSTRAINT `employee_ibfk_1` FOREIGN KEY (`dep_id`) REFERENCES `department` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=26 DEFAULT CHARSET=utf8;
- 权限表
CREATE TABLE `permission` (
`pid` bigint(20) NOT NULL,
`pname` varchar(50) DEFAULT NULL,
`presource` varchar(50) DEFAULT NULL,
PRIMARY KEY (`pid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
- 角色与权限中间表
CREATE TABLE `employee_role_rel` (
`eid` bigint(20) NOT NULL,
`rid` bigint(20) NOT NULL,
PRIMARY KEY (`eid`,`rid`),
KEY `rid` (`rid`),
CONSTRAINT `employee_role_rel_ibfk_1` FOREIGN KEY (`eid`) REFERENCES `employee` (`id`),
CONSTRAINT `employee_role_rel_ibfk_2` FOREIGN KEY (`rid`) REFERENCES `role` (`rid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
使用代码生成器生成相关mapper
2.建立角色页面
角色数据列表
<table id="emp_dg"></table>
<div id="toolbar">
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-add',plain:true" id="add">添加</a>
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-edit',plain:true" id="edit">编辑</a>
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-remove',plain:true" id="remove">离职</a>
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-reload',plain:true" id="reload">刷新</a>
</div>
添加角色权限对话框
<div id="dialog">
<form id="myform">
<table align="center" style="border-spacing: 20px 30px">
<input type="hidden" name="id">
<tr align="center">
<td>角色编号: <input type="text" name="username" class="easyui-validatebox" ></td>
<td>角色名称: <input type="text" name="username" class="easyui-validatebox" ></td>
</tr>
<tr>
<td><div id="role_data1"></div></td>
<td><div id="role_data2"></div></td>
</tr>
</table>
</form>
</div>
3.加载权限数据实现点击添加权限，点击删除权限
/*角色数据列表*/
$("#role_dg").datagrid({
url:"/getRoles",
columns:[[
{field:'rnum',title:'角色编号',width:100,align:'center'},
{field:'rname',title:'角色名称',width:100,align:'center'},
]],
fit:true,
fitColumns:true,
rownumbers:true,
pagination:true,
singleSelect:true,
striped:true,
toolbar:"#toolbar",
});
/*权限列表*/
$("#role_data1").datagrid({
title:"所有权限",
width:250,
height:400,
fitColumns:true,
singleSelect:true,
url:'/permissionList',
columns:[[
{field:'pname',title:'权限名称',width:100,align:'center'},
]],
onClickRow:function (rowIndex,rowData) {/*点击一行时,回调*/
/*判断是否已经存在该权限*/
/*取出所有的已选权限*/
var allRows = $("#role_data2").datagrid("getRows");
/*取出每一个进行判断*/
for(var i = 0; i<allRows.length; i++){
/*取出每一行*/
var row = allRows[i];
if(rowData.pid == row.pid){/*已经存在该权限*/
/*让已经存在权限成为选中的状态*/
/*获取已经成为选中状态当前角标*/
var index = $("#role_data2").datagrid("getRowIndex",row);
/*让该行成为选中状态*/
$("#role_data2").datagrid("selectRow",index);
return;
}
}
/*把当前选中的,添加到已选权限*/
$("#role_data2").datagrid("appendRow",rowData);
}
});
/*选中权限列表*/
$("#role_data2").datagrid({
title:"已选权限",
width:250,
height:400,
singleSelect:true,
fitColumns:true,
columns:[[
{field:'pname',title:'权限名称',width:100,align:'center'},
]],
onClickRow:function (rowIndex,rowData) {
/*删除当中选中的一行*/
$("#role_data2").datagrid("deleteRow",rowIndex);
}
});
4.添加角色权限
定义角色权限关系:一个角色有多个权限
@Getter@Setter@ToString
public class Role {
private Long rid;
private String rnum;
private String rname;
/*一个角色可以有多个权限*/
private List<Permission> permissions = new ArrayList<>();
}
点击保存时,如果没有隐藏字段id,则为添加操作
保存时, 参数传递；默认只传递input中的内容,还需要在提交表单时, 把添加的权限信息提交过去
/*添加/编辑对话框*/
$("#dialog").dialog({
width:600,
height:650,
buttons:[{
text:'保存',
handler:function(){
/*判断当前是保存操作还是编辑操作*/
var rid = $("[name='rid']").val();
var url;
if(rid){
/*编辑*/
url="updateRole"
}else {
/*保存*/
url="saveRole";
}
/*提交表单*/
$("#myform").form("submit",{
url:url,
onSubmit:function(param){ /*传递额外参数 已选择的权限*/
/*获取已经选择的权限*/
var allRows = $("#role_data2").datagrid("getRows");
/*遍历出每一个权限*/
for(var i = 0; i< allRows.length; i++){
/*取出每一个权限 */
var row = allRows[i];
/*给它封装到集合中*/
param["permissions["+i+"].pid"] = row.pid;
}
},
success:function (data) {
data = $.parseJSON(data);
if (data.success){
$.messager.alert("温馨提示",data.msg);
/*关闭对话框 */
$("#dialog").dialog("close");
/*重新加载数据表格*/
$("#role_dg").datagrid("reload");
} else {
$.messager.alert("温馨提示",data.msg);
}
}
});
}
},{
text:'关闭',
handler:function(){
$("#dialog").dialog("close");
}
}],
closed:true
});
接收参数,保存角色与权限
/*接收 保存角色请求地址*/
@RequestMapping("/saveRole")
@ResponseBody
public AjaxRes saveRole(Role role){
AjaxRes ajaxRes = new AjaxRes();
try {
/*调用业务层, 保存角色和权限*/
roleService.saveRole(role);
ajaxRes.setMsg("保存成功");
ajaxRes.setSuccess(true);
}catch (Exception e){
ajaxRes.setSuccess(false);
ajaxRes.setMsg("保存失败");
}
return ajaxRes;
}
@Override
public void saveRole(Role role) {
/*1.保存角色*/
roleMapper.insert(role);
/*2.保存角色与权限之间关系*/
for (Permission permission : role.getPermissions()) {
roleMapper.insertRoleAndPermissionRel(role.getRid(),permission.getPid());
}
}
5.角色列表
/*角色数据列表*/
$("#role_dg").datagrid({
url:"/getRoles",
columns:[[
{field:'rnum',title:'角色编号',width:100,align:'center'},
{field:'rname',title:'角色名称',width:100,align:'center'},
]],
fit:true,
fitColumns:true,
rownumbers:true,
pagination:true,
singleSelect:true,
striped:true,
toolbar:"#toolbar",
});
6.编辑角色权限
编辑回显
/*监听编辑点击*/
$("#edit").click(function () {
/*获取当前选中的行*/
var rowData = $("#role_dg").datagrid("getSelected");
console.log(rowData);
if(!rowData){
$.messager.alert("提示","选择一行数据进行编辑");
return;
}
/*加载当前角色下的权限*/
var options = $("#role_data2").datagrid("options");
options.url = "/getPermissionByRid?rid="+rowData.rid;
/*重新加载数据*/
$("#role_data2").datagrid("load");
/*选中数据的回示*/
$("#myform").form("load",rowData);
/*设置标题*/
$("#dialog").dialog("setTitle","编辑角色");

$("#dialog").dialog("open");
/*回显部门*/
// 当rowData["department"]为空时，会异常
if(rowData["department"] != null)
{
rowData["department.id"] = rowData["department"].id;
}
else
rowData["department.id"] = rowData["department"]+"";
/*回显管理员*/
rowData["admin"] = rowData["admin"]+"";
/*回显角色*/
/*根据当前用户的id,查出对应的角色*/
$.get("/getRoleByEid?id="+rowData.id,function (data) {
/*设置下拉列表数据回显*/
$("#role").combobox("setValues",data);

<artifactId>shiro-spring</artifactId>
<version>1.4.0</version>
</dependency>
1.登录拦截,如果没有登录,跳转到登录页面
1.在web.xml当中配置过滤器拦截所有请求,进行处理
<!-- 拦截到所有请求,使用spring一个bean来进行处理 -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<!-- 是否filter中的init和destroy-->
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2.在spring当中配置shiro过滤器和安全管理器
<!-- 配置shiro过滤器 -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager"></property>
<!-- 配置shiro过滤器pattern -->
<property name="filterChainDefinitions">
<value>
/static/** = anon <!--不需要登录验证-->
/login.jsp = anon <!--不需要登录验证-->
/**=authc <!--除指定请求外,其它所有的请求都需要身份验证-->
</value>
</property>
</bean>
<!-- 配置shiro安全管理器 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"></bean>
2.登录认证流程
1.表单发送请求
$(function () {
$("#loginBtn").click(function () {
/*Ajax发送请求, 是没有办法跳转服务当中的请求
* 只能通过在浏览器当中来跳转
* */
$.post("/login",$("form").serialize(),function (data) {
/*把data json格式的字符串 转成 json 数据*/
data = $.parseJSON(data);
if (data.success){
/*跳转到首页*/
window.location.href = "/index.jsp"
} else {
alert(data.msg);
}
});
});
});
2.指定登录认证路径
<!-- 配置登录认证的路径 -->
<property name="loginUrl" value="/login" />
3.创建登录realm和重新配置过滤器
public class EmployeeRealm extends AuthorizingRealm {
@Autowired
private EmployeeService employeeService;
/*认证*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("来到了认证-------");
/*获取身份信息*/
String username = (String)token.getPrincipal();
System.out.println(username);
/*根据用户名当中查询有没有当前用户*/
Employee employee = employeeService.getEmployeeWithUserName(username);
System.out.println(employee);
if (employee == null){
return null;
}
/*认证*/
/*参数: 主体,正确的密码,盐,当前realm名称*/
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(
employee,
employee.getPassword(),
ByteSource.Util.bytes(employee.getUsername()),
this.getName());
return info;
}
/*授权
web doGetAuthorizationInfo 什么时候调用
1.发现访问路径对应的方法上面 有授权注解 就会调用doGetAuthorizationInfo
2.页面当中有授权标签 也会调用doGetAuthorizationInfo
* */
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("授权调用-------------------");
/*获取用户的身份信息*/
Employee employee = (Employee) principalCollection.getPrimaryPrincipal();
/*根据当前用,查询角色和权限*/
List<String> roles = new ArrayList<>();
List<String> permissions = new ArrayList<>();
/*判断当前用户是不是管理员 如果是管理员 拥有所有的权限*/
if(employee.getAdmin()){
/*拥有所有的权限*/
permissions.add("*:*");
}else {
/*查询角色*/
roles = employeeService.getRolesById(employee.getId());
/*查询权限*/
permissions = employeeService.getPermissionById(employee.getId());
}
/*给授权信息*/
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
info.addRoles(roles);
info.addStringPermissions(permissions);
return info;
}
}
4.配置realm数据源（在application-shiro.xml中配置）
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
">
<bean id="myFormFilter" class="com.itlike.web.filter.MyFormFilter"/>
<!-- 配置shiro过滤器 -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<!--
index
其它的请求 会判断 当前有没有认证过
默认情况 , 没有认证,会跳转到login.jsp
如果配置了 loginUrl 没有认证 执行对应的login请求
login
loginUrl:如果发现请求是loginUrl值 会去做认证
配置登录认证的路径
-->
<property name="loginUrl" value="/login"/>
<!--重新配置表单监听的过滤器-->
<property name="filters">
<map>
<entry key="authc" value-ref="myFormFilter"/>
</map>
</property>
<!--配置安全管理器-->
<property name="securityManager" ref="securityManager"></property>
<!-- 配置shiro过滤器pattern -->
<property name="filterChainDefinitions">
<value>
/static/** = anon <!--不需要登录验证-->
/login.jsp = anon <!--不需要登录验证-->
/logout = logout <!--取消认证-->
/**=authc <!--除指定请求外,其它所有的请求都需要身份验证-->
</value>
</property>
</bean>
<!--自定义realm-->
<bean id="employeeRealm" class="com.itlike.web.realm.EmployeeRealm">
<property name="credentialsMatcher" ref="credentialsMatcher"/>
</bean>
<!-- 凭证匹配器 -->
<bean id="credentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
<!-- 散列算法 -->
<property name="hashAlgorithmName" value="md5"/>
<!-- 散列次数 -->
<property name="hashIterations" value="2"></property>
</bean>
<!-- 缓存管理器 -->
<bean id="ehCache" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:shiro-ehcache.xml"/>
</bean>
<!-- 配置shiro安全管理器 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<!--注入realm-->
<property name="realm" ref="employeeRealm"/>
<!--注入缓存-->
<property name="cacheManager" ref="ehCache"/>
</bean>
<!--
配置为true即使用cglib继承的方式,
false为jdk的接口动态代理 控制器没有实现接口
-->
<aop:config proxy-target-class="true" ></aop:config>
<!-- 使用第三方去扫描shiro的注解 -->
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor ">
<property name="securityManager" ref="securityManager"></property>
</bean>
</beans>
5.创建表单认证过滤器
public class MyFormFilter extends FormAuthenticationFilter {
/*当认证成功时,会调用*/
protected boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request, ServletResponse response) throws Exception {
/*响应给浏览器*/
response.setCharacterEncoding("utf-8");
System.out.println("认证成功");
AjaxRes ajaxRes = new AjaxRes();
ajaxRes.setSuccess(true);
ajaxRes.setMsg("登录成功");
/*把对象转成json格式字符串*/
String jsonString = new ObjectMapper().writeValueAsString(ajaxRes);
response.getWriter().print(jsonString);
return false;
}
/*当认证失败时, 会调用*/
protected boolean onLoginFailure(AuthenticationToken token,
AuthenticationException e,
ServletRequest request,
ServletResponse response) {
System.out.println("认证失败");
AjaxRes ajaxRes = new AjaxRes();
ajaxRes.setSuccess(false);
if (e!=null){
/*获取异常名称*/
String name = e.getClass().getName();
if(name.equals(UnknownAccountException.class.getName())){
/*没有帐号*/
ajaxRes.setMsg("帐号不正确");
} else if(name.equals(IncorrectCredentialsException.class.getName())){
/*密码错误*/
ajaxRes.setMsg("密码不正确");
}else {
/*未知异常*/
ajaxRes.setMsg("未知错误");
}
}
try {
/*把对象转成json格式字符串*/
String jsonString = new ObjectMapper().writeValueAsString(ajaxRes);
response.setCharacterEncoding("utf-8");
response.getWriter().print(jsonString);
} catch (IOException e1) {
e1.printStackTrace();
}
/*响应给浏览器*/
return false;
}
}
登录授权
当我们在控制器方法写了 @RequiresPermissions,Shiro在访问时, 就会判断有没有该权限
如果没有,就不会执行对应方法
实现过程
1.在配置文件当中添加Shiro注解扫描
<!--
配置为true即使用cglib继承的方式,
false为jdk的接口动态代理 控制器没有实现接口
-->
<aop:config proxy-target-class="true" ></aop:config> <!-- 使用第三方去扫描shiro的注解 -->
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor ">
<property name="securityManager" ref="securityManager"></property>
</bean>
2.在realm中添加授权信息
public class EmployeeRealm extends AuthorizingRealm {
@Autowired
private EmployeeService employeeService;
/*认证*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("来到了认证-------");
/*获取身份信息*/
String username = (String)token.getPrincipal();
System.out.println(username);
/*根据用户名当中查询有没有当前用户*/
Employee employee = employeeService.getEmployeeWithUserName(username);
System.out.println(employee);
if (employee == null){
return null;
}
/*认证*/
/*参数: 主体,正确的密码,盐,当前realm名称*/
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(
employee,
employee.getPassword(),
ByteSource.Util.bytes(employee.getUsername()),
this.getName());
return info;
}
/*授权
web doGetAuthorizationInfo 什么时候调用
1.发现访问路径对应的方法上面 有授权注解 就会调用doGetAuthorizationInfo
2.页面当中有授权标签 也会调用doGetAuthorizationInfo
* */
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("授权调用-------------------");
/*获取用户的身份信息*/
Employee employee = (Employee) principalCollection.getPrimaryPrincipal();
/*根据当前用,查询角色和权限*/
List<String> roles = new ArrayList<>();
List<String> permissions = new ArrayList<>();
/*判断当前用户是不是管理员 如果是管理员 拥有所有的权限*/
if(employee.getAdmin()){
/*拥有所有的权限*/
permissions.add("*:*");
}else {
/*查询角色*/
roles = employeeService.getRolesById(employee.getId());
/*查询权限*/
permissions = employeeService.getPermissionById(employee.getId());
}
/*给授权信息*/
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
info.addRoles(roles);
info.addStringPermissions(permissions);
return info;
}
}
没有权限结果处理
@ExceptionHandler(AuthorizationException.class)
public void handleShiroException(HandlerMethod method,HttpServletResponse response) throws Exception{ /*method 发生异常的方法*/
/*跳转到一个界面 界面提示没有 权限*/
/*判断 当前的请求是不是Json请求 如果是 返回json给浏览器 让它自己来做跳转*/
/*获取方法上的注解*/
ResponseBody methodAnnotation = method.getMethodAnnotation(ResponseBody.class);
if (methodAnnotation != null){
//Ajax
AjaxRes ajaxRes = new AjaxRes();
ajaxRes.setSuccess(false);
ajaxRes.setMsg("你没有权限操作");
String s = new ObjectMapper().writeValueAsString(ajaxRes);
response.setCharacterEncoding("utf-8");
response.getWriter().print(s);
}else {
response.sendRedirect("nopermission.jsp");
}
}
权限按钮控制
- 引入Shiro的标签库
- 在需要权限控制的地方添加对应的shiro标签
<%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro" %>
<shiro:hasPermission name="employee:add">
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-add',plain:true" id="add">添加</a>
</shiro:hasPermission>
密码散列
在保存用户时, 给用户密码进行加密处理
/*把密码进行加密*/
把用户名作为盐值，进行2次散列
Md5Hash md5Hash = new Md5Hash(employee.getPassword(), employee.getUsername(), 2);
employee.setPassword(md5Hash.toString());
在认证当中添加密码处理
/*认证*/
/*参数: 主体,正确的密码,盐,当前realm名称*/
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(
employee,
employee.getPassword(),
ByteSource.Util.bytes(employee.getUsername()),
this.getName());
添加凭证匹配器
<!-- 配置realm数据源 -->
<bean id="employeeRealm" class="com.itlike.realm.EmployeeRealm">
<property name="credentialsMatcher" ref="credentialsMatcher"/>
</bean>
<!-- 凭证匹配器 -->
<bean id="credentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
<!-- 散列算法 -->
<property name="hashAlgorithmName" value="md5"/>
<!-- 散列次数 -->
<property name="hashIterations" value="2"></property>
</bean>
权限缓存
- 进入页面时, 页面当中写了Shiro的标签,每一个标签都要去到授权当中进行一次授权查询
- 授权查询只使用一次即可, 所以使用缓存,把对应的内容缓存起来,下次再去, 直接从缓存当中进行查询
使用步骤:
1.添加缓存pom依赖
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.2</version>
</dependency>
2.添加shiro缓存配置
添加shiro-ehcache.xml
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<defaultCache
maxElementsInMemory="1000"
maxElementsOnDisk="10000000"
eternal="false"
overflowToDisk="false"
diskPersistent="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LRU">
</defaultCache>
</ehcache>
配置约束
3.application-shiro中配置缓存管理器
<!-- 缓存管理器 -->
<bean id="ehCache" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:shiro-ehcache.xml"/>
</bean>
4.把缓存管理器添加到安全管理器当中
<!-- 配置shiro安全管理器 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="employeeRealm" />
<property name="cacheManager" ref="ehCache"/>
</bean>
菜单权限管理
菜单页面
页面搭建
1.创建菜单表
CREATE TABLE `menu` (
`id` bigint(20) NOT NULL,
`text` varchar(10) DEFAULT NULL,
`url` varchar(30) DEFAULT NULL,
`parent_id` bigint(20) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `parent_id` (`parent_id`),
CONSTRAINT `menu_ibfk_1` FOREIGN KEY (`parent_id`) REFERENCES `menu` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
2.生成Mapper，添加父菜单字段
@Setter@Getter@ToString
public class Menu {
private Long id;
private String text;
private String url;
private Menu parent;
private Permission permission;
private List<Menu> children = new ArrayList<>();
}
3.创建Menu页面
<!-- 数据表格 -->
<table id="menu_datagrid">
<thead>
<tr>
<th>名称</th>
<th>url</th>
<th>父菜单</th>
</tr>
</thead>
</table>
<!-- 数据表格CRUD按钮 -->
<div id="menu_toolbar">
<div>
<a class="easyui-linkbutton" iconCls="icon-add" plain="true" id="add">新增</a>
<a class="easyui-linkbutton" iconCls="icon-edit" plain="true" id="edit">编辑</a>
<a class="easyui-linkbutton" iconCls="icon-remove" plain="true" id="del">刪除</a>
<a class="easyui-linkbutton" iconCls="icon-reload" plain="true" id="reload">刷新</a>
</div>
</div>
<div id="menu_dialog">
<form id="menu_form" method="post">
<table align="center" style="margin-top: 15px;">
<input type="hidden" name="id">
<tr>
<td>名称</td>
<td><input type="text" name="text"></td>
</tr>
<tr>
<td>url</td>
<td><input type="text" name="url"></td>
</tr>
<tr>
<td>父菜单</td>
<td><input type="text" id="parentMenu" name="parent.id" class="easyui-combobox" placeholder="请选择父菜单"/></td>
</tr>
</table>
</form>
</div>
<!-- 对话框保存取消按钮 -->
<div id="menu_dialog_bt">
<a class="easyui-linkbutton" iconCls="icon-save" plain="true" id="save">保存</a>
<a class="easyui-linkbutton" iconCls="icon-cancel" plain="true" id="cancel">取消</a>
</div>

} else {
$.messager.alert("温馨提示",data.msg);
}
});
}
});
});
});
菜单列表
1.接收菜单请求
@Service
public class MenuServiceImpl implements MenuService {
@Autowired
private MenuMapper menuMapper;
@Override
public PageListRes getMenuList(QueryVo vo) {
/*调用mapper 查询菜单 */
Page<Object> page = PageHelper.startPage(vo.getPage(), vo.getRows());
List<Menu> menus = menuMapper.selectAll();
/*封装成pageList*/
PageListRes pageListRes = new PageListRes();
pageListRes.setTotal(page.getTotal());
pageListRes.setRows(menus);
return pageListRes;
}
}
2.底层实现
<resultMap id="BaseResultMap" type="com.itlike.domain.Menu" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="text" property="text" jdbcType="VARCHAR" />
<result column="url" property="url" jdbcType="VARCHAR" />
<association property="parent" javaType="com.itlike.domain.Menu" columnPrefix="m_">
<result property="id" column="id"/>
<result property="text" column="text"/>
<result property="url" column="url"/>
</association>
<association property="permission" javaType="com.itlike.domain.Permission">
<result property="pid" column="pid"/>
<result property="pname" column="pname"/>
<result property="presource" column="presource"/>
</association>
<collection property="children" ofType="com.itlike.domain.Menu" select="listChildMenu" column="id"/>
</resultMap>
<!-- /*查询所有菜单*/-->
<select id="selectAll" resultMap="BaseResultMap" >
SELECT
m1.id,
m1.text,
m1.url,
m2.id as m_id,
m2.text as m_text,
m2.url as m_url
from menu as m1
LEFT JOIN menu as m2
ON m1.parent_id = m2.id
order by m1.id desc
</select>
3.页面处理
formatter这个属性属于列参数，意思就是对当前列的数据进行格式化操作，它是一个函数，有三个参数，value，row，index,
value:代表当前单元格中的值，
row：代表当前行,
index:代表当前行的下标,
可以使用return 返回你想要的数据显示在单元格中;
formatter:function(value,row,index){
return value?value.text:'';
}
菜单添加
获取所有父菜单
<tr>
<td>父菜单</td>
<td><input type="text" id="parentMenu" name="parent.id" class="easyui-combobox" placeholder="请选择父菜单"/></td>
</tr>
$(function () {
/*加载选择父菜单*/
$("#parentMenu").combobox({
width:150,
panelHeight:'auto',
editable:false,
url:'parentList',
textField:'text',
valueField:'id',
onLoadSuccess:function () { /*数据加载完毕之后回调*/
$("#parentMenu").each(function(i){
var span = $(this).siblings("span")[i];
var targetInput = $(span).find("input:first");
if(targetInput){
$(targetInput).attr("placeholder", $(this).attr("placeholder"));
}
});
}
});
});
保存菜单
监听保存点击
/*保存菜单*/
$("#save").click(function () {
/*判断当前是添加 还是编辑*/
var id = $("[name='id']").val();
var url;
if(id){
var parent_id = $("[name='parent.id']").val();
if (id == parent_id) {
$.messager.alert("温馨提示","不能设置自己为父菜单");
return;
}
/*编辑*/
url = "updateMenu";
}else {
/*添加*/
url= "saveMenu";
}
/*提交表单*/
$("#menu_form").form("submit",{
url:url,
success:function (data) {
data = $.parseJSON(data);
if (data.success){
$.messager.alert("温馨提示",data.msg);
/*关闭对话框 */
$("#menu_dialog").dialog("close");
$("#parentMenu").combobox("reload");
$("#menu_datagrid").datagrid("reload");
} else {
$.messager.alert("温馨提示",data.msg);
}
}
});
});
业务处理
/*保存菜单*/
@RequestMapping("/saveMenu")
@ResponseBody
public AjaxRes saveMenu(Menu menu){
AjaxRes ajaxRes = new AjaxRes();
try {
/*调用业务层,保存菜单*/
menuService.saveMenu(menu);
ajaxRes.setMsg("保存成功");
ajaxRes.setSuccess(true);
}catch (Exception e){
ajaxRes.setSuccess(false);
ajaxRes.setMsg("保存失败");
System.out.println(e);
}
return ajaxRes;
}
编辑菜单
/*编辑菜单*/
$("#edit").click(function () {
$("#menu_form").form("clear");
/*获取当前选中的行*/
var rowData = $("#menu_datagrid").datagrid("getSelected");
if(!rowData){
$.messager.alert("提示","选择一行数据进行编辑");
return;
}
/*父菜单回显*/
if(rowData.parent){
rowData["parent.id"] = rowData.parent.id;
}else {/*回显的placeholder*/
$("#parentMenu").each(function(i){
var span = $(this).siblings("span")[i];
var targetInput = $(span).find("input:first");
if(targetInput){
$(targetInput).attr("placeholder", $(this).attr("placeholder"));
}
});
}
/*弹出对话框*/
$("#menu_dialog").dialog("setTitle","编辑菜单");
$("#menu_dialog").dialog("open");
/*选中数据的回示*/
$("#menu_form").form("load",rowData);
});
删除菜单
监听删除按钮
$("#del").click(function () {
/*获取当前选中的行*/
var rowData = $("#menu_datagrid").datagrid("getSelected");
if(!rowData){
$.messager.alert("提示","选择一行数据进行删除");
return;
}
/*提醒用户,是否做删除操作*/
$.messager.confirm("确认","是否做删除操作",function (res) {
if(res){
/*做离职操作*/
$.get("/deleteMenu?id="+rowData.id,function (data) {
if (data.success){
$.messager.alert("温馨提示",data.msg);
/*重新加载下拉列表数据*/
$("#parentMenu").combobox("reload");
/*重新加载数据表格*/
$("#menu_datagrid").datagrid("reload");
} else {
$.messager.alert("温馨提示",data.msg);
}
});
}
});
});
处理业务逻辑
@Override
public AjaxRes deleteMenu(Long id) {
AjaxRes ajaxRes = new AjaxRes();
try {
/*1.打破菜单关系*/
menuMapper.updateMenuRel(id);
/*2.删除记录*/
menuMapper.deleteByPrimaryKey(id);
ajaxRes.setMsg("删除成功");
ajaxRes.setSuccess(true);
}catch (Exception e){
ajaxRes.setSuccess(false);
ajaxRes.setMsg("删除失败");
System.out.println(e);
}
return ajaxRes;
}
<!--根据id删除菜单-->
<delete id="deleteByPrimaryKey" parameterType="java.lang.Long" >
delete from menu
where id = #{id,jdbcType=BIGINT}
</delete>
<!--根基id更新菜单-->
<update id="updateByPrimaryKey" parameterType="com.itlike.domain.Menu" >
update menu
set text = #{text},
url = #{url},
parent_id = #{parent.id}
where id = #{id}
</update>
菜单权限
在**menu**数据表中, 添加外键, 每一个菜单对应一个权限,通过判断用户有没有该权限来控制菜单的显示隐藏
设置菜单对应权限并取出
1.在menu表中添加权限外键
2.在菜单domain当中添加权限对象
tree数据加载
$(function () {
$("#tabs").tabs({
fit:true
})
$('#tree').tree({
url:"/getTreeData",
lines:true,
onSelect: function(node){
/*在添加之前, 做判断 判断这个标签是否存在 */
var exists = $("#tabs").tabs("exists",node.text);
if(exists){
/*存在,就让它选中*/
$("#tabs").tabs("select",node.text);
}else {
if (node.url !=''&& node.url !=null){
/*如果不存在 ,添加新标签*/
$("#tabs").tabs("add",{
title:node.text,
/*href:node.attributes.url,*/ /*href 引入的是body当中*/
content:"<iframe src="+node.url+" frameborder='0' width='100%' height='100%'></iframe>",
closable:true
})
}
}
},
onLoadSuccess: function (node, data) {
console.log(data[0].children[0].id);
if (data.length > 0) {
//找到第一个元素
var n = $('#tree').tree('find', data[0].children[0].id);
//调用选中事件
$('#tree').tree('select', n.target);
}
}
});
});
3.查询菜单时, 把对应权限查出来, 检查权限
@Override
public List<Menu> getTreeData() {
List<Menu> treeData = menuMapper.getTreeData();
/*
判断当前用户有没有对应的权限
如果没有就从集合当中移除
*/
/*获取用户 判断用户是否是管理员 是管理就不需要做判断*/
Subject subject = SecurityUtils.getSubject();
/*当前的用户*/
Employee employee = (Employee)subject.getPrincipal();
if (!employee.getAdmin()){
/*做检验权限*/
checkPermission(treeData);
}
return treeData;
}
public void checkPermission(List<Menu> menus){
//获取主体
Subject subject = SecurityUtils.getSubject();
//遍历所有的菜单及子菜单
Iterator<Menu> iterator = menus.iterator();
while (iterator.hasNext()){
Menu menu = iterator.next();
if (menu.getPermission() !=null){
//判断当前menu是否有权限对象,如果说没有 当前遍历的菜单从集合当中移除
String presource = menu.getPermission().getPresource();
if (!subject.isPermitted(presource)){
//当前遍历的菜单从集合当中移除
iterator.remove();
continue;
}
}
/*判断是否有子菜单 有子菜单也要做权限检验*/
if (menu.getChildren().size() > 0){
checkPermission(menu.getChildren());
}
}
}
<resultMap id="BaseResultMap" type="com.itlike.domain.Menu" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="text" property="text" jdbcType="VARCHAR" />
<result column="url" property="url" jdbcType="VARCHAR" />
<association property="parent" javaType="com.itlike.domain.Menu" columnPrefix="m_">
<result property="id" column="id"/>
<result property="text" column="text"/>
<result property="url" column="url"/>
</association>
<association property="permission" javaType="com.itlike.domain.Permission">
<result property="pid" column="pid"/>
<result property="pname" column="pname"/>
<result property="presource" column="presource"/>
</association>
<collection property="children" ofType="com.itlike.domain.Menu" select="listChildMenu" column="id"/>
</resultMap>
<!--获取树形菜单数据
分步查询 先查根菜单
根据根菜单的id 查询出子菜单
-->
<select id="getTreeData" resultMap="BaseResultMap">
select * from menu as m
LEFT JOIN permission as p
on m.permission_id = p.pid where parent_id is null
</select>
<!--根据根菜单的id 查询出子菜单-->
<select id="listChildMenu" resultMap="BaseResultMap">
select * from menu as m
LEFT JOIN permission as p
on m.permission_id = p.pid where parent_id = #{id}
</select>
系统日志
建立日志表和对应mapper
CREATE TABLE `systemlog` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`optime` datetime DEFAULT NULL,
`ip` varchar(20) DEFAULT NULL,
`function` varchar(255) DEFAULT NULL,
`params` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
添加拦截器,记录当前请求的ip
创建本地线程变量
public class RequestUtil {
public static ThreadLocal<HttpServletRequest> local = new ThreadLocal();
public static HttpServletRequest getRequest(){
return local.get();
}
public static void setRequest(HttpServletRequest request){
local.set(request);
}
}
配置拦截器拦截所有请求
<!--配置拦截器-->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/*"/>
<bean class="com.itlike.interceptor.RequestInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>
创建拦截器把当前请求写入到本地线程变量
public class RequestInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
System.out.println("来到了拦截器...");
RequestUtil.setRequest(request);
return true;
}
}
Systemlog systemlog = new Systemlog();
//设置ip地址 request 添加拦截器 获取请求对象
HttpServletRequest request = RequestUtil.getRequest();
if (request != null){
String IP = request.getRemoteAddr();
System.out.println(IP);
systemlog.setIp(IP);
}
创建日志切面、在切面中获取ip、获取当前执行的方法及参数
public class SystemAspect {
@Autowired
private SystemlogMapper systemlogMapper;
public void writeLog(JoinPoint joinPoint) throws JsonProcessingException {
System.out.println("记录日志");
//设置时间
Systemlog systemlog = new Systemlog();
systemlog.setOptime(new Date());
//设置ip地址 request 添加拦截器 获取请求对象
HttpServletRequest request = RequestUtil.getRequest();
if (request != null){
String IP = request.getRemoteAddr();
System.out.println(IP);
systemlog.setIp(IP);
}
//方法
//获取目标执行方法的全路径
String name = joinPoint.getTarget().getClass().getName();
//获取方法名称
String signature = joinPoint.getSignature().getName();
String func = name+":"+signature;
systemlog.setFunction(func);
//获取方法参数
String params = new ObjectMapper().writeValueAsString(joinPoint.getArgs());
systemlog.setParams(params);
systemlogMapper.insert(systemlog);
}
}
添加切面
<!-- aop配置 日志配置 -->
<bean id="SystemAspect" class="com.itlike.aspect.SystemAspect"></bean>
<aop:config>
<aop:pointcut expression="execution(* com.itlike.service.*.*(..))" id="servicePoint" />
