jasig cas java示例_Java cas 实例 客户端配置（三）

第二步 客户端web应用程序集成CAS

1. 从官网下载CAS Client

将客户端的jar，cas-client-core-3.2.1.jar   commons-logging-1.1.jar 引入到web应用程序的classpath中

2 .配置web.xml文件，

主要是添加过滤器拦截通信， 下面实例代码， 假设web应用程序的端口是8888

CAS Single Sign Out Filter

org.jasig.cas.client.session.SingleSignOutFilter

CAS Single Sign Out Filter

/*

org.jasig.cas.client.session.SingleSignOutHttpSessionListener

CASFilter

org.jasig.cas.client.authentication.AuthenticationFilter

casServerLoginUrl

http://localhost:8888/cas-server/login

serverName

http://localhost:8888/

CASFilter

/*

CAS Validation Filter

org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter

redirectAfterValidation

true

casServerUrlPrefix

http://localhost:8888/cas-server

serverName

http://localhost:8888/

renew

false

gateway

false

CAS Validation Filter

/*

3、启动报错如下

java.lang.RuntimeException: java.io.FileNotFoundException: https://localhost:8443/serviceValidate?ticket=ST-1-1HUXO9iETnaNI2jbuvqK-cas01.example.org&service=http%3A%2F%2Flocalhost%3A8080%2FCasClient%2FIndex.jsp

org.jasig.cas.client.util.CommonUtils.getResponseFromServer(CommonUtils.java:328)

org.jasig.cas.client.util.CommonUtils.getResponseFromServer(CommonUtils.java:291)

org.jasig.cas.client.validation.AbstractCasProtocolUrlBasedTicketValidator.retrieveResponseFromServer(AbstractCasProtocolUrlBasedTicketValidator.java:32)

org.jasig.cas.client.validation.AbstractUrlBasedTicketValidator.validate(AbstractUrlBasedTicketValidator.java:187)

org.jasig.cas.client.validation.AbstractTicketValidationFilter.doFilter(AbstractTicketValidationFilter.java:164)

org.jasig.cas.client.authentication.AuthenticationFilter.doFilter(AuthenticationFilter.java:102)

原因：

4、测试是否会跳转到cas验证页面，以及登录成功后会不会回到原页面

5、在系统的登出事件中， 将URL访问地址指向CAS服务登出的servlet

http://CAS服务器IP:8080/cas/logout
