cas client 3.2.1 环境搭建
接着上一节内容继续搭建客户端，搭建客户端新建一个web project ,需要的包，我截图上来吧，我是结合spring+hibernate 注解配置
如果不配置 spring hibernate ,只有mysql-connector-java.jar,cas-client-core.jar就可以了
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath:applicationContext.xml
org.jasig.cas.client.session.SingleSignOutHttpSessionListener
CAS Single Sign Out Filter
org.jasig.cas.client.session.SingleSignOutFilter
CAS Single Sign Out Filter
/*
CASFilter
org.jasig.cas.client.authentication.AuthenticationFilter
casServerLoginUrl

index.jsp
以上是我的web.xml 配置。com.jyd.filter.AutoSetUserAdapterFilter 过滤器呢是自定义的，例如登录成功后要把用户信息放入到session中
/**
* 过滤逻辑：首先判断单点登录的账户是否已经存在本系统中，
* 如果不存在使用用户查询接口查询出用户对象并设置在Session中
* @see Filter#doFilter(ServletRequest, ServletResponse, FilterChain)
*/
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
// _const_cas_assertion_是CAS中存放登录用户名的session标志
Object object = httpRequest.getSession().getAttribute(AbstractCasFilter.CONST_CAS_ASSERTION);
if (object != null) {
Assertion assertion = (Assertion) object;
String loginName = assertion.getPrincipal().getName();
User user = UserUtil.getCurrentUser(httpRequest.getSession());
// 第一次登录系统
if (user == null) {
WebApplicationContext wct = WebApplicationContextUtils.getWebApplicationContext(httpRequest
.getSession().getServletContext());
UserService userService = (UserService) wct.getBean("userService");
user = userService.findUserByLoginName("userName" ,loginName);
// 保存用户信息到Session
UserUtil.saveUserToSession(httpRequest.getSession(), user);
}
}
chain.doFilter(request, response);
