实现过程 从cas-server-3.3.1modules中找出cas.war放到tomcat/webapps下面(cas-server-webapp-3.3.1.war重命名即可)。 现在cas默认的server端已经有了，下面自己写2个客户端测试一下MyEclipse里面新建web project:新建类HelloWorldExample package servlet; import java.io.IOException; import java.io.PrintWriter; import java.util.Enumeration; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public final class HelloWorldExample extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { response.setContentType(text/html); PrintWriter writer = response.getWriter(); writer.println(html); writer.println(head); writer.println(titleSample Application Servlet Page/title); writer.println(/head); writer.println(body bgcolor=white); writer.println(table border=\0\); writer.println(tr); writer.println(td); writer.println(img src=\images/tomcat.gif\); writer.println(/td); writer.println(td); writer.println(h1Sample Application Servlet/h1); writer.println(This is the output of a servlet that is part of); writer.println(the Hello, World application.); writer.println(/td); writer.println(/tr); writer.println(/table); writer.println(/body); writer.println(/html); } } 在web.xml文件添加CASFilter与servlet映射。 ?xml version=1.0 encoding=GB18030? web-app version=2.4 xmlns=/xmls/j2ee xmlns:xsi=/2001/XMLSchema-instance xsi:schemaLocation=/xmls/j2ee /xmls/j2ee/web-app_2_4.xsd filter filter-nameCAS Filter/filter-name filter-classedu.yale.its.tp.cas.client.filter.CASFilter/filter-class init-param param-nameedu.yale.its.tp.cas.client.filter.loginUrl/param-name param-value:8443/cas/login/param-value /init-param init-param param-nameedu.yale.its.tp.cas.client.filter.validateUrl/param-name p
