之前的文章讲了如何用cas配置单点登录，其中各个子站的web.xml中都有配置cas的各种过滤器比较麻烦，这一节我们来讲一下cas与shiro的整合。

cas服务器和之前的文章配置一样的不用变，现在这是需要在客户端与shiro整合就ok

第一步：添加如下依赖包

<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>${shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>${shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-cas</artifactId>
<version>${shiro.version}</version>
</dependency>
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client</artifactId>
<version>3.2.1</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-core</artifactId>
<version>2.6.6</version>
</dependency>

第二步:在classpath下面添加一个application-shiro.xml 内容如下

ps:其中jdbc.properties中定义了

#sso配置
casServer=https://www.ssomain.com:8443/cas
appServer=http://www.cui.com:8090/cui //这两个域名都是本地解析为127.0.0.1 因为我都在本地的同一个tomcat中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<description>Shiro CAS配置</description>
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager" />
<property name="loginUrl" value="${casServer}/login?service=${appServer}/shiro-cas" />
<property name="filters">
<util:map>

<entry key="casFilter" value-ref="casFilter"></entry>
</util:map>
</property>
<property name="filterChainDefinitions">
<value>
/shiro-cas = casFilter
/** = anon
</value>
</property>
</bean>


<bean id="casFilter" class="org.apache.shiro.cas.CasFilter">

<property name="failureUrl" value="/index.jsp"></property>
<property name="successUrl" value="/index.jsp" />
</bean>

<bean id="casRealm" class="org.apache.shiro.cas.CasRealm">
<property name="casServerUrlPrefix" value="${casServer}"/>

<property name="casService" value="${appServer}/shiro-cas"/>
</bean>


<bean id="shiroEhcacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:ehcache/ehcache-shiro.xml"/>
</bean>

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

<property name="cacheManager" ref="shiroEhcacheManager" />
<property name="realm" ref="casRealm" />
</bean>

<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>

第三步：在web.xml中添加如下

<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>、

然后启动tomcat 在浏览器里面输入 http:www.cui.com:8090/cui 就会跳到cas登录页面

在这个过程中遇到各种问题大部分问题都是包冲突

还有一个问题我需要强调一下就是，登录的时候页面一直报“页面中包含重定向” 最后原因是因为我的配置文件没有加载对搞了半天很坑爹

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:/applicationContext.xml,
classpath*:/applicationContext-shiro.xml
</param-value>
</context-param>

我写成这样了

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:/applicationContext.xml,

</param-value>

<param-value>

classpath*:/applicationContext-shiro.xml
</param-value>
</context-param>
