Spring + SpringMVC + MyBatis
1.需求说明
实现用户通过数据库验证登录需求，采用Myeclipse+Tomcat 6.0+Mysql 5.0+JDK 1.6
2.数据库表
开发所用是Mysql数据库,只建立单张用户表T_USER,表结构如下：
字段名称 数据类型 字段描述
ID int 用户编号
USERNAME VARCHAR 用户名
PASSWORD VARCHAR 用户登录密码
sql语句如下：
CREATE TABLE `t_user` (
`ID` int(11) NOT NULL auto_increment,
`USERNAME` varchar(255) default NULL,
`PASSWORD` varchar(255) default NULL,
PRIMARY KEY (`ID`)
);
3.构建源代码目录
4.用到的jar包(见附件Archive.rar)
5.各项Xml配置文件详解
(1)web.xml文件(Tomcat使用)
服务器根据配置内容初始化spring框架，springmvc框架和log4j日志框架

(6)sqlMapConfig.xml(Ibatis框架配置文件)
该文件主要负责指定sql映射文件，即与model层对象对应的映射文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<!-- 配置settings -->
<settings lazyLoadingEnabled="true" useStatementNamespaces="false"/>
<!-- 配置sql映射文件 -->
<sqlMap resource="com/archie/model/User.xml"/>
</sqlMapConfig>
6.Java代码编写
根据包目录，可以看出分成model层,dao层,service层和web层,另外附加test层,用于java环境测试
(1)model层(User.java+User.xml)
User.java代码
package com.archie.model;
public class User {
private int id;
private String username;
private String password;
public User(){
}
public User(int id){
this.id = id;
}
public User(int id, String username){
this.id = id;
this.username = username;
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
public User(int id, String username, String password){
this.id = id;
this.username = username;
this.password = password;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
User.xml代码(model层对象的sql映射文件,被dao层调用,本质是sql语句集合,所有相关的sql均于此)
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">
<typeAlias alias="User" type="com.archie.model.User"/>
<select id="findAllUser" resultClass="User" >
select * from t_user
</select>
<select id="findUserByID" resultClass="User" parameterClass="int">
select * from t_user where id=#id#
</select>
<select id="getTotalCount" resultClass="int">
select count(*) from t_user
</select>
<select id="searchUsers" resultClass="User" parameterClass="User">
select * from t_user
<dynamic prepend="where">
<!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 -->
<isNotEmpty prepend="and" property="username">
(username like '%$username$%')
</isNotEmpty>
<isNotEmpty prepend="and" property="password">
(password like '%$password$%')
</isNotEmpty>
</dynamic>
</select>
<select id="findUserByNameAndPassword" resultClass="User" parameterClass="User">
select * from t_user where username=#username# and password=#password#
</select>
<insert id="insertUser" parameterClass="User">
insert into t_user(id,username,password) values(null,#username#,#password#)
</insert>
<update id="updateUser" parameterClass="User">
update t_user
set username = #username#,
password=#password#
where id=#id#
</update>
<delete id="deleteUser" parameterClass="int">
delete from t_user where id=#id#
</delete>
<delete id="deleteUserByLike" parameterClass="User">
delete from t_user
<dynamic prepend="where">
<!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 -->
<isNotEmpty prepend="and" property="username">
(username like '%$username$%')
</isNotEmpty>
<isNotEmpty prepend="and" property="password">
(password like '%$password$%')
</isNotEmpty>
</dynamic>
</delete>
</sqlMap>
(2)dao层(数据服务层,BaseDao.java+UserDao.java)
BaseDao.java(公共Dao,其他Dao均继承它)
package com.archie.dao;
import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.ibatis.sqlmap.client.SqlMapClient;
public class BaseDao extends SqlMapClientDaoSupport {
@Resource(name="sqlMapClient") //通过bean名称注入
private SqlMapClient sqlMapClient;
@PostConstruct //完成sqlMapClient初始化工作
public void initSqlMapClient(){
super.setSqlMapClient(sqlMapClient);
}
}
UserDao.java(user数据服务层)
package com.archie.dao;
import java.util.List;
import org.springframework.stereotype.Component;
import com.archie.model.User;
@Component //将UserDao类注入到bean里面
public class UserDao extends BaseDao {
public boolean addUser(User user) throws Exception{
User bean = (User)getSqlMapClientTemplate().insert("insertUser", user);
return bean != null ? true : false;
}
public boolean deleteUser(int id) throws Exception{
int result = getSqlMapClientTemplate().delete("deleteUser", id);
return result > 0 ? true : false;
}
public User getUserById(int id) throws Exception{
return (User)getSqlMapClientTemplate().queryForObject("findUserByID", id);
}
@SuppressWarnings("unchecked")
public List getAllUsers() throws Exception{
return getSqlMapClientTemplate().queryForList("findAllUser");
}
public boolean updateUser(User user) throws Exception{
int result = getSqlMapClientTemplate().update("updateUser", user);
return result > 0 ? true : false;
}
public User getUserByNameAndPassword(User user) throws Exception{
return (User)getSqlMapClientTemplate().queryForObject("findUserByNameAndPassword", user);
}
public int getTotalCount() throws Exception{
return (Integer)getSqlMapClientTemplate().queryForObject("getTotalCount");
}
@SuppressWarnings("unchecked")
public List getUsersByLike(User user) throws Exception{
return getSqlMapClientTemplate().queryForList("searchUsers", user);
}
public int deleteUserByLike(User user) throws Exception{
int result = getSqlMapClientTemplate().delete("deleteUserByLike", user);
if (result > 0) {
System.out.println("模糊删除成功！");
}else {
System.out.println("没有匹配的记录1");
}
return result;
}
}
(3)service层(业务服务层,UserService.java)
UserService.java代码如下
package com.archie.service;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import com.archie.dao.UserDao;
import com.archie.model.User;
@Component //将UserService类注入到bean里面
@Transactional //注入事务管理
public class UserService {
@Resource(name="userDao") // 通过名称注入到bean里面
private UserDao userDao;
public User login(User user) throws Exception{
return userDao.getUserByNameAndPassword(user);
}
public void addUser(User user) throws Exception{
userDao.addUser(user);
}
public void deleteUser(int id) throws Exception{
boolean bool = userDao.deleteUser(id);
if (!bool) {
System.out.println("删除的记录不存在！");
throw new RuntimeException();
}
}
public User getUserById(int id) throws Exception{
User user = userDao.getUserById(id);
if (user == null) {
return null;
}
return userDao.getUserById(id);
}
public void updateUser(User user) throws Exception{
userDao.updateUser(user);
}
public int getTotalCount() throws Exception{
return userDao.getTotalCount();
}
@SuppressWarnings("unchecked")
public List getUsersByLike(User user) throws Exception{
return userDao.getUsersByLike(user);
}
public int deleteUserByLike(User user) throws Exception{
return userDao.deleteUserByLike(user);
}
public void insertUsers(List<User> list) throws Exception{
for (int i = 0; i < list.size(); i++) {
if (i > 3) {
System.out.println("列表太长，中断事务");
throw new RuntimeException("中断事务异常,当列表长度大于3的时候故意抛出，看看事务是否回滚");
}
User user = list.get(i);
userDao.addUser(user);
}
}
}
(4)web层(界面控制层,UserController.java)
UserController.java
package com.archie.web;
import javax.annotation.Resource;
import javax.servlet.http.HttpSession;
import javax.validation.Valid;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.archie.model.User;
import com.archie.service.UserService;
@Controller
@RequestMapping("/user/*")
public class UserController {
@Resource(name="userService")
private UserService userService;
private final String LIST="redirect:/detail";
/**
* 登录
* @param user
* @param session
* @return
*/
@RequestMapping("/login")
public ModelAndView login(@Valid User user,BindingResult result,HttpSession session) throws Exception{
if(!result.hasErrors()){
User loginUser=userService.login(user);
if(loginUser!=null){
session.setAttribute("USER", loginUser);
return new ModelAndView(LIST);
}else{
return new ModelAndView("redirect:/");
}
}else{
ModelAndView view=new ModelAndView();
view.setViewName("redirect:/");
view.addObject("error", result.getAllErrors());
return view;
}
}
/**
* 跳转至添加页
* @return
*/
@RequestMapping(value="/toAdd",method=RequestMethod.GET)
public ModelAndView toAdd(){
return new ModelAndView("user/add");
}
/**
* 保存
* @param user
* @return
*/
@RequestMapping(value="/add",method=RequestMethod.POST)
public ModelAndView add(@Valid User user,BindingResult result) throws Exception{
if(result.hasErrors()){
return new ModelAndView("user/add","error", result.getAllErrors());
}else{
userService.addUser(user);
return new ModelAndView(LIST);
}
}
/**
* 根据ID删除
* @param id
* @return
*/
@RequestMapping(value="/delete/{id}")
public ModelAndView delete(@PathVariable int id) throws Exception{
userService.deleteUser(id);
return new ModelAndView(LIST);
}
/**
* 跳转至编辑页面
* @param id
* @return
*/
@RequestMapping(value="/edit/{id}")
public ModelAndView edit(@PathVariable int id) throws Exception{
User user=userService.getUserById(id);
return new ModelAndView("user/edit","user",user);
}
/**
* 编辑
* @param user
* @return
*/
@RequestMapping(value="/edit")
public ModelAndView update(@Valid User user,BindingResult result)throws Exception{
ModelAndView view=new ModelAndView();
if(result.hasErrors()){
view.addObject("error", result.getAllErrors());
view.setViewName("user/edit");
return view;
}else{
userService.updateUser(user);
return new ModelAndView(LIST);
}
}
}
(5)test层(Java环境下测试)
TestUserController.java
package com.archie.test;
import java.util.ArrayList;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.archie.model.User;
import com.archie.service.UserService;
public class TestUserController {
public static void main(String[] args) throws Exception{
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
UserService userService = (UserService)context.getBean("userService");
List<User> list = new ArrayList<User>();
list.add(new User("wang", "wang"));
list.add(new User("wang", "wang"));
list.add(new User("wang", "wang"));
userService.insertUsers(list);
System.out.println("恭喜恭喜，添加成功！");
userService.deleteUser(26);
System.out.println("恭喜恭喜，删除成功！");
User beanUser = userService.getUserById(21);
if (beanUser != null) {
System.out.println("恭喜恭喜，查找成功！");
}else {
System.out.println("不好意思，您所查找的用户不存在！");
}
int totalCount = userService.getTotalCount();
System.out.println("TotalCount="+totalCount);
int result = userService.deleteUserByLike(new User("wang","wang"));
System.out.println("模糊删除的记录条数是："+result);
List users = userService.getUsersByLike(new User("meimei","1234"));
if (users == null || users.size() == 0) {
System.out.println("没有匹配的记录2");
}else {
for (int i = 0; i < users.size(); i++) {
User user = (User)users.get(i);
System.out.println("username="+user.getUsername()+",password="+user.getPassword());
}
}
System.out.println("length="+users.size());
}
