篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了cas4.2.7与shiro进行整合相关的知识，希望对你有一定的参考价值。
准备工作
cas单点登录开始前准备，请参考cas4.2.7实现单点登录。
与shiro进行整合
注：准备工作的基础上，对cas客户端进行如下改进。
引入相关jar包
shiro-cas-1.2.6.jar
shiro-core-1.2.6.jar
shiro-spring-1.2.6.jar
shiro-web-1.2.6.jar
web.xml引入shiro过滤器

引入shiro的配置文件
<?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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:property-placeholder location="classpath:shiro.properties" ignore-unresolvable="true"/> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"/> <!-- 设定角色的登录链接，这里为cas登录页面的链接可配置回调地址 --> <property name="loginUrl" value="${cas.loginUrl}" /> <property name="successUrl" value="${shiro.successUrl}" /> <property name="filters"> <map> <entry key="casFilter" value-ref="casFilter"/> </map> </property> <property name="filterChainDefinitions"> <value> /shiro-cas = casFilter /** = authc </value> </property> </bean> <bean id="casFilter" class="org.apache.shiro.cas.CasFilter"> <property name="failureUrl" value="${shiro.failureUrl}"/> </bean> <bean id="ShiroCasRealm" class="com.hjzgg.client.shiro.ShiroCasRealm"/> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="ShiroCasRealm"/> <property name="subjectFactory" ref="casSubjectFactory"/> </bean> <bean id="casSubjectFactory" class="org.apache.shiro.cas.CasSubjectFactory"/> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> <property name="staticMethod" value="org.apache.shiro.SecurityUtils.setSecurityManager"/> <property name="arguments" ref="securityManager"/> </bean> </beans>
引入shiro的需要属性
cas.loginUrl=http://127.0.0.1:8080/cas-web/login?service=http://127.0.0.1:8080/cas-client/shiro-cas
cas.logoutUrl=http://127.0.0.1:8080/cas-web/logout?service=http://127.0.0.1:8080/cas-client/shiro-cas
cas.serverUrlPrefix=http://127.0.0.1:8080/cas-web
shiro.cas.service=http://127.0.0.1:8080/cas-client/shiro-cas
shiro.failureUrl=/error
shiro.successUrl=/success
自定义shiro的realm
