2.配置在web.xml里配置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>
  </filter>
  <filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

这里的<filter-name>shiroFilter</filter-name>中的shiroFilter必须跟shiro配置文件中的真实的filter bean id一致
3.创建shiro配置文件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:mvc="http://www.springframework.org/schema/mvc"
         xmlns:context="http://www.springframework.org/schema/context"
         xmlns:aop="http://www.springframework.org/schema/aop"
         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">
    <!--<bean-->
            <!--class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"-->
            <!--depends-on="lifecycleBeanPostProcessor" />-->
     <!--&lt;!&ndash;配置自定义的realm&ndash;&gt;-->
       <bean id="UserRealm" class="shiro.UserRealm"></bean>
     <!--配置安全管理器Securitymanager-->
     <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
         <property name="realm" ref="UserRealm"/>
     </bean>
    <!--自定义shiroFilter-->
     <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
         <property name="securityManager" ref="securityManager"/>
         <property name="loginUrl" value="/login"/>
         <property name="unauthorizedUrl" value="/nopermission.jsp"/>
         <property name="filterChainDefinitions">
             <value>
                 /**=authc
             </value>
         </property>
     </bean>
    <!--开启aop对类代理-->
    <aop:config expose-proxy="true"></aop:config>
    <!--开启shiro注解支持-->
    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
        <property name="securityManager" ref="securityManager"/>
    </bean>
    <!--定义需要特殊处理的异常,用类名或完全路径名作为key,异常页名作为value-->
    <!--shiro权限异常处理-->
    <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <property name="exceptionMappings">
            <props>
                <prop key="org.apache.shiro.authz.UnauthorizedException">redirect:/nopermission.jsp</prop>
            </props>
        </property>
    </bean>
</beans>

3.创建认证,授权令牌

package shiro;
import csd.entity.User;
import csd.service.UserService;
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 javax.annotation.Resource;
import java.util.ArrayList;
import java.util.List;

public class UserRealm extends AuthorizingRealm {
    public UserRealm() {
        System.out.println("实例化了令牌");
    }

    public String getName() {
        return "UserRealm";
    }
    @Resource(name = "Iuser")
    private UserService userService;
    //授权操作
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("授权进行中");
        User user = (User)principalCollection.getPrimaryPrincipal();
        List<String> permissions = new ArrayList<String>();
        if ("10086".equals(user.getUsername())) {
            permissions.add("employee:edit");
        } else if ("admin".equals(user.getUsername())) {
            permissions.add("*:*");
        }
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        info.addStringPermissions(permissions);
        return info;
    }

    //认证操作
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("认证进行中");
        String username=(String) authenticationToken.getPrincipal();
        //System.out.println("令牌的username为"+username);
        User user = userService.login(username);
        if (user == null){
            return null;
        }
        AuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getPassword(), getName());
        return info;
    }
}

        System.out.println("用户名加密码"+user.getUsername()+","+user.getPassword());
        //如果认证失败就从reques中获取异常信息,shiroLoginFailure是shiro异常类的权限命名

            UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
            try {

    public String index(Model model, HttpServletRequest req)throws Exception{
        System.out.println("进入了login方法");

    }
}

package csd.controller;
