spring 整合shiro框架 模拟登录控制器。
一、导入shiro jar包。 我在maven项目中，将常用的jar包都放在里面。
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

<!--如果指定该参数，执行过程会输出到控制台--> <verbose>true</verbose> </configuration> </plugin> </plugins> </build> </project>
二、在资源目录下创建 shiro.xml文件 我在这里 对admin目录下的文件进行拦截。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--1.安全管理器--> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <!--缓存管理器 暂时不引用他--> <!--<property name="cacheManager" ref="cacheManager"/>--> <!--会话的模式--> <property name="sessionMode" value="native"/> <!--配置realm --> <property name="realm" ref="myRealm"/> </bean> <!--2.缓存管理器--> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> </bean> <bean id="myRealm" class="com.aaa.realm.MyRealm"> <property name="name" value="myRealm"/> <!--3.品证（密码）匹配器--> <!-- <property name="credentialsMatcher"> <!– The 'bootstrapDataPopulator' Sha256 hashes the password (using the username as the salt) then base64 encodes it: –> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <property name="hashAlgorithmName" value="SHA-256"/> <!– true means hex encoded, false means base64 encoded –> <property name="storedCredentialsHexEncoded" value="false"/> </bean> </property>--> </bean> <!--4.shiro中的类型要交给 spring容器管理的bean--> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <!--5.启用注解配置--> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean> <!-- 6. shiro 的过滤器 id和名字保持一致 和web.xml 中过滤器的名字保持一致。否则配置没有效果。 --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <!--1.引入安全管理器 --> <property name="securityManager" ref="securityManager"/> <!--2.登录的地址 --> <property name="loginUrl" value="/login.jsp"/> <!--3.登录成功的页面 --> <property name="successUrl" value="/index.jsp"/> <!--4.绑定一个未授权的路径。--> <property name="unauthorizedUrl" value="/unauthorized.jsp"/> <!-- <property name="filters"> <util:map> <entry key="aName" value-ref="someFilterPojo"/> </util:map> filterChainDefinitions 过滤器的规则声明。 1.anon 匿名不需要验证 2. authc 认证 需要登录 3.perms 权限 4.logout 注销 /admin/** = authc 下的路径都需要进行登录认证 从上到下 前面规定好的 冲突就是优先级。 </property> --> <property name="filterChainDefinitions"> <value> /login.jsp = anon /index.jsp = anon /static/** =anon # allow WebStart to pull the jars for the swing app: /*.jar = anon # everything else requires authentication: /emp/**=authc /admin/** = authc </value> </property> </bean> </beans>
三、在spring全局配置文件中 加载shiro的配置，最后一行。
<?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: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/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--spring的全局配置文件--> <context:component-scan base-package="com.aaa"/> <!--加载外部资源文件--> <context:property-placeholder location="classpath:jdbc.properties"/> <!--配置数据源--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <!-- 配置初始化大小、最小、最大 --> <property name="initialSize" value="5" /> <property name="minIdle" value="10" /> <property name="maxActive" value="20" /> <!-- 配置获取连接等待超时的时间 --> <property name="maxWait" value="60000" /> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="2000" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="600000" /> <property name="maxEvictableIdleTimeMillis" value="900000" /> <property name="validationQuery" value="select 1" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="keepAlive" value="true" /> <property name="phyMaxUseCount" value="100000" /> <!-- 配置监控统计拦截的filters --> <property name="filters" value="stat" /> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!--配置mybatis的映射文件--> <property name="mapperLocations" value="classpath:mapper/*.xml"/> <property name="typeAliasesPackage" value="com.aaa.entity"/> <!--配置mybatis分页插件 --> <property name="plugins"> <array> <bean class="com.github.pagehelper.PageInterceptor"> <property name="properties"> <value> helperDialect=mysql </value> </property> </bean> </array> </property> <!--如果使用mybatis的配置文件--> <!--<property name="configLocation" value="classpath:mybatis-config.xml"/>--> </bean> <!--扫描：dao接口--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.aaa.dao"/> </bean> <!--配置事务管理器--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!--事务的注解配置--> <tx:annotation-driven transaction-manager="transactionManager"/> <!--在spring全局配置文件中 加载shiro的配置--> <import resource="shiro.xml"/> </beans>
四、在web.xml文件中 添加shiro过滤器
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <!--上下文参数--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!--监听器--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置编码方式过滤器,注意一点:要配置在所有过滤器的前面 --> <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> <!-- shiro过滤器--> <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> <!-- 拦截页面上所有发过来的请求。 1.实现模拟put 方法 --> <filter> <filter-name>hiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>hiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--前端控制器 默认加载web-inf/[servlet-name]-servlet.xml --> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:mvc.xml</param-value> </init-param> <!--随着服务器启动而启动--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
五、控制层 用户登录的后台管理。 realm层 MyRealm的设置。
5.1 realm 层 MyRealm
package com.aaa.realm; import org.apache.shiro.authc.*; import org.apache.shiro.realm.AuthenticatingRealm; /*1.编码实现realm类 * 2.继承AuthenticatingRealm * * 3.返回一个实现类 验证交给shiro * * realm * * 1.获取subject传递过来的token * 2.根据token中的用户名，找到密码 * 3.返回认证的对象。 * */ public class MyRealm extends AuthenticatingRealm { @Override //令牌信息 从表单中传递过来的身份信息 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { UsernamePasswordToken usernamePasswordToken= (UsernamePasswordToken) authenticationToken; //获取令牌中的用户名 String username = usernamePasswordToken.getUsername(); //连接数据库 进行查询操作 根据用户名 查询密码 模拟密码 String password="666"; //返回认证信息 SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(username,password,getName()); return info; } }
5.2 控制层 UserController
package com.aaa.controller; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.*; import org.apache.shiro.subject.Subject; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import javax.servlet.http.HttpSession; @Controller @RequestMapping("/user") public class UserController { //获取日志对象 private static final transient Logger log= LoggerFactory.getLogger(UserController.class); @RequestMapping("/login") public String login(String username,String password, HttpSession session){ Subject currentUser= SecurityUtils.getSubject(); if (!currentUser.isAuthenticated()){ UsernamePasswordToken token = new UsernamePasswordToken(username, password); //记住我 // token.setRememberMe(true); try { //调用Suject.login方法 ---》安全管理器--->认证器 ，授权器 currentUser.login(token); } catch (UnknownAccountException uae) {//账号不存在 log.info("There is no user with username of " + token.getPrincipal()); } catch (IncorrectCredentialsException ice) {//密码错误 log.info("Password for account " + token.getPrincipal() + " was incorrect!"); //密码错误 直接显示一个异常 提示用户 throw new IncorrectCredentialsException("密码错误"); } catch (LockedAccountException lae) {//账号锁死 log.info("The account for username " + token.getPrincipal() + " is locked. " + "Please contact your administrator to unlock it."); } // ... catch more exceptions here (maybe custom ones specific to your application? catch (AuthenticationException ae) { //unexpected condition? error? } } return "view/ok"; } }
六、过滤器的jsp
<%-- Created by IntelliJ IDEA. User: Administrator Date: 2019/8/11 Time: 20:28 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>登录界面</title> </head> <body> <h1> 过滤器的简单测试 </h1> <form action="user/login" method="post"> <div>用户名：<input type="text" name="username"> </div> <div>密码：<input type="text" name="password"> </div> <div><input type="submit" value="登录"> </div> </form> </body> </html>
七、 我在shiro中对admin 目录下的资源进行了过滤，需要登录验证。用户名和密码不匹配，就会抛出一个错误。
异常信息
