在http://downloads.jasig.org/cas-clients/cas-client-3.2.1-release.zip，这是客户端源码，在modules文件夹中有需要的jar，maven依赖

<span style="font-family:Microsoft YaHei;"><dependency>    <groupId>org.jasig.cas</groupId>    <artifactId>cas-client-core</artifactId>    <version>3.2.1</version></dependency></span>

加入log4j包

<dependency>    <groupId>commons-logging</groupId>    <artifactId>commons-logging</artifactId>    <version>1.1</version></dependency>

配置log4j.propertis

<span style="font-family:Microsoft YaHei;">log4j.rootLogger=DEBUG,Console,Filelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.Target=System.outlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%c]%m%nlog4j.appender.File=org.apache.log4j.RollingFileAppender log4j.appender.File.File=cas-client.loglog4j.appender.File.MaxFileSize=10MBlog4j.appender.File.Threshold=ALLlog4j.appender.File.layout=org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n</span>

配置web.xml

<span style="font-family:Microsoft YaHei;"><?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">    <!-- ======================== 单点登录开始 ======================== -->    <!-- 配置单点退出。如果此处不配置，不能单点退出，并且要放到所有过滤器的最前面 -->    <listener>        <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>    </listener>    <filter>        <filter-name>SingleSignOutFilter</filter-name>        <filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>SingleSignOutFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- cas过滤器 -->    <filter>        <filter-name>CAS Authentication Filter</filter-name>        <filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>        <init-param>            <param-name>casServerLoginUrl</param-name>            <param-value>https://login.wodsy.com:8443/login</param-value>            <!--此处配置cas服务器端的登录地址-->        </init-param>        <init-param>            <param-name>serverName</param-name>            <param-value>http://www.tomcat2.com:8085</param-value>            <!-- 此处配置客户端地址（即项目访问地址，同样配置了hosts映射到www.tomcat2.com上，端口为8085） -->        </init-param>    </filter>    <filter-mapping>        <filter-name>CAS Authentication Filter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!--ticket过滤器 -->    <filter>        <filter-name>CAS Validation Filter</filter-name>        <filter-class>            org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter        </filter-class>        <init-param>            <param-name>casServerUrlPrefix</param-name>            <param-value>https://login.wodsy.com:8443</param-value>        </init-param>        <init-param>            <param-name>serverName</param-name>            <param-value>http://www.tomcat2.com:8085</param-value>            <!--//这里配置的客户端的地址-->        </init-param>    </filter>    <filter-mapping>        <filter-name>CAS Validation Filter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!--允许cas包裹HttpServletRequest，客户端就可以使用getRemoteUser和getPrincipal获取到服务器端返回的相关信息-->    <!-- ======================== 单点登录结束 ======================== -->    <welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list></web-app></span>

为了看到登录后效果，添加一个index.jsp在根目录下

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title></title></head><body>  <h1>登陆成功</h1></body></html>

现在同时启动两个tomcat（注意不要端口冲突，在%TOMCAT_HOME%conf/server.xml中配置），访问客户端地址，

http://www.tomcat2.com:8085（hosts自行配置）会自动跳转到服务器登录页，并带上返回链接的参数，请求的地址如下：

https://login.wodsy.com:8443/login?service=http%3A%2F%2Fwww.tomcat2.com%3A8085%2F，注意service参数的内容即登录成功后的跳转页。

输入帐号：admin，密码：admin即成功登录，返回客户端

到此客户端的简单配置成功
