            </configuration>

        </plugin>

    </plugins> -->

  </build>

</project>

2.引入Spring，Springmvc以及spring与mybatis集成并配置相关属性
在src/main/resources创建spring，springmvc的配置文件，这里创建了spring-mybatis.xml，spring-mvc.xml，信息如下：

<?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"

        xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!-- 导入配置文件 -->

    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!-- druid 数据源 -->

    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">

        <property name="url"  value="${jdbc.url}"></property>

        <property name="username" value="${jdbc.username}"></property>

        <property name="password" value="${jdbc.password}"></property>

    </bean>

    <!-- 扫描mybatis 配置文件-->

    <bean name="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="dataSource" />

        <property name="mapperLocations" value="classpath:com/peng/entity/mapper/*.xml" />

    </bean>

    <!-- 扫描Mapper 配置文件-->

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <property name="basePackage" value="com.peng.mapper" />

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

    </bean>

</beans>

<?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"

        xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!-- 使用spring组件扫描@controller -->

    <context:component-scan base-package="com.peng.web.controller"/>

    <!-- 通过annotation-driven可以替代下边的处理器映射器和适配器 -->

    <!-- 自动注解 -->

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></bean>

    <!-- 视图解析器 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />

        <property name="prefix" value="/WEB-INF/jsp/" />

        <property name="suffix" value=".jsp" />

    </bean>

</beans>

3.引入Mybatis并配置数据连接池等信息
在src/main/resources创建配置连接池配置信息在jdbc.properties中，如下：

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/ssms?useUnicode=true&characterEncoding=UTF-8

jdbc.username=root

jdbc.password=root

4.引入日志配置log4j打印信息到后台
在src/main/resources创建log4j.properties，如下：

#定义LOG输出级别

log4j.rootLogger=INFO,Console,File

#定义日志输出目的地为控制台

log4j.appender.Console=org.apache.log4j.ConsoleAppender

log4j.appender.Console.Target=system.out

#可以灵活地指定日志输出格式，下面一行是指定具体的格式 %d [%t]%-5p [%c] - %m%n

log4j.appender.Console.layout = org.apache.log4j.PatternLayout

log4j.appender.Console.layout.ConversionPattern=[%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

#文件大小到达指定尺寸的时候产生一个新的文件

log4j.appender.File = org.apache.log4j.RollingFileAppender

#指定输出目录

log4j.appender.File.File = d:/logs/ssms.log

#定义文件最大大小

log4j.appender.File.MaxFileSize = 10MB

# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志

log4j.appender.File.Threshold = ALL

log4j.appender.File.layout = org.apache.log4j.PatternLayout

log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

5.web.xml 配置spring监听器，对springmvc的支持，shiro的filter 如下：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xmlns="http://java.sun.com/xml/ns/javaee"

         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

  <display-name>ssms</display-name>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

  <!-- Spring监听器 -->

  <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>classpath:spring-shiro.xml,classpath:spring-mybatis.xml</param-value>

  </context-param>

  <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <!-- shiro的filter -->

  <filter>

    <filter-name>shiroFilter</filter-name>

    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

    <init-param>

        <param-name>targetFilterLifecycle</param-name>

        <param-value>true</param-value>

    </init-param>

    <init-param>

        <param-name>targetBeanName</param-name>

        <param-value>shiroFilter</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>shiroFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

  <!-- 添加对springmvc的支持 -->

 <servlet>

    <servlet-name>springmvc</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>classpath:spring-mvc.xml</param-value>

    </init-param>

    <load-on-startup>1</load-on-startup>

    <async-supported>true</async-supported>

  </servlet>

  <servlet-mapping>

    <servlet-name>springmvc</servlet-name>

    <url-pattern>/</url-pattern>

  </servlet-mapping>

  <!-- post乱码处理 -->

  <filter>

    <filter-name>CharacterEncodingFilter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <init-param>

        <param-name>encoding</param-name>

        <param-value>utf-8</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>CharacterEncodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

</web-app>

6.集成spring与shiro权限管理配置文件spring-shiro.xml
在src/main/resources创建spring-shiro.xml

<?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"

        xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!-- 使用spring组件扫描@service  -->

    <context:component-scan base-package="com.peng.service"/>

    <!-- 自定义域realm -->

    <bean id="custom_Realm" class="com.peng.realm.CustomRealm"></bean>

    <!-- 安全管理器  ref对象-->

    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">

        <property name="realm" ref="custom_Realm"/>

    </bean>

    <!-- shiro filter -->

    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">

        <!-- 安全管理器必须的 -->

        <property name="securityManager" ref="securityManager"/>

        <!-- 身份认证失败   认证提交的地址 -->

        <property name="loginUrl" value="/index.jsp"/>

        <!-- 权限认证失败    没有权限认证提交的地址 -->

        <property name="unauthorizedUrl" value="/unauthorized.jsp"/>

        <!-- Shiro连接约束配置,即过滤链的定义 -->

        <property name="filterChainDefinitions">

            <value>

                <!-- 对静态资源设置匿名访问 -->

                /login = anon

                <!-- /** = authc 所有url都必须认证通过才可以访问 -->

                /admin* = authc

            </value>

        </property>

    </bean>

    <!-- Shiro生命周期处理器 -->

    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"></bean>

    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

        <property name="securityManager" ref="securityManager"/>

    </bean>

</beans>

7.自定义域realm

package com.peng.realm;

import org.apache.shiro.authc.AuthenticationException;

import org.apache.shiro.authc.AuthenticationInfo;

import org.apache.shiro.authc.AuthenticationToken;

import org.apache.shiro.authc.SimpleAuthenticationInfo;

import org.apache.shiro.authz.AuthorizationInfo;

import org.apache.shiro.authz.SimpleAuthorizationInfo;

import org.apache.shiro.realm.AuthorizingRealm;

import org.apache.shiro.subject.PrincipalCollection;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import com.peng.entity.User;

import com.peng.service.UserService;

public class CustomRealm extends AuthorizingRealm{

    private static final Logger logger = LoggerFactory.getLogger(CustomRealm.class);

    @Autowired

    private UserService userService;

    /**

     * 用户授权认证

     */

    @Override

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

        logger.info("======用户授权认证======");

        String userName = principalCollection.getPrimaryPrincipal().toString();

        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();

        simpleAuthorizationInfo.setRoles(userService.queryRolesByName(userName));

        return simpleAuthorizationInfo;

    }

    /**

     * 用户登陆认证

     */

    @Override

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        logger.info("======用户登陆认证======");

        String userName = authenticationToken.getPrincipal().toString();

        User user = userService.queryUserByName(userName);

        if (user!=null) {

            AuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user.getUserName(), user.getPassword(), "peng");

            return authenticationInfo;

        }

        return null;

    }

}

8.、UserMapper以及UserMapper.xml相当于Dao层
UserMapper接口

public interface UserMapper {

    public User queryUserByName(String userName);

    public Set<String> queryRolesByName(String userName);

}

9.UserMapper.xml配置sql语句

<?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.peng.mapper.UserMapper">

    <select id="queryUserByName" resultType="com.peng.entity.User" parameterType="java.lang.String">

        SELECT id,userName,password FROM user WHERE userName=#{userName}

    </select>

    <select id="queryRolesByName" resultType="java.lang.String" parameterType="java.lang.String">

        SELECT name FROM role r,user_role ur,user u WHERE r.id = ur.roleId AND u.id = ur.userId AND u.userName=#{userName}

    </select>

</mapper>

10.Service层创建UserService

@Service("userService")

public class UserService {

    @Autowired

    private UserMapper userMapper;

    public User queryUserByName(String userName){

        return userMapper.queryUserByName(userName);

    }

    public Set<String> queryRolesByName(String userName){

        return userMapper.queryRolesByName(userName);

    }

}

11.Controller层创建LoginController

@Controller

public class LoginController {

    private static final Logger logger = LoggerFactory.getLogger(LoginController.class);

    @Autowired

    private UserService userService;

    @RequestMapping("/login")

    public String login(User user,Model model){

        Subject subject = SecurityUtils.getSubject();

        UsernamePasswordToken usernamePasswordToken = new

                UsernamePasswordToken(user.getUserName(),user.getPassword());

        try {

            subject.login(usernamePasswordToken);

            logger.info("======登陆成功=======");

            return "success";

        } catch (Exception e) {

            logger.error("======登陆异常=======");

            //model.addAttribute("msg", "用户名或者密码错误,登陆失败");

            e.printStackTrace();

            return "/i````

dex";

        }

    }

}

12.前段登陆界面测试

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:set var="ctx" value="${pageContext.request.contextPath}" />

<%@ page language="java" contentType="text/html; charset=utf-8"

    pageEncoding="utf-8"%>

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8" />

    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <title>登录页面</title>

    <link rel="stylesheet" href="${ctx}/static/css/reset.css" />

    <link rel="stylesheet" href="${ctx}/static/css/login.css" />

    <script type="text/javascript" src="${ctx}/static/js/jquery.min.js"></script>

                                        <span id="count-msg" class="error"></span>

                </li>

                <li class="login-item">

    </div>

</div>

<script type="text/javascript">

        window.onload = function() {

            var config = {

                vx : 4,

                vy : 4,

                height : 2,

                width : 2,

                count : 100,

                color : "121, 162, 185",
