1. 开发工具：myeclipse 2014 / IDEA；
2. maven管理版本：apache-maven-3.0+；
3. jdk 1.7.0+
4. Tomcat8.0
二：工程搭建：

1、修改pom.xml添加对应的包依赖

        </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">

           </form>
        </div>
    </div>
</div>
<script type="text/javascript">
        window.onload = function() {
            var config = {
                vx : 4,
                vy : 4,
                height : 2,
