cas4.0 單點登錄 之 cas-client
cas4.0 單點登錄 之 https證書?已經做好了證書的準備工作，現在結合cas-server來配置單點登錄；
一、安裝cas服務端（cas-server)
cas服務端是一個war包，這里只做體驗單點登錄，cas-server下載點這里cas-server-webapp-4.0.0.war，將war包放tomcat下運行即可，運行cas-server的tomcat的要開啟SSL支持，上面文章也有說明，server.xml需要如下配置：
<Connector port="8443" protocol="HTTP/1.1" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="d:/cas/keystore" keystorePass="caspass"/>- 1

cas-server的定制開發后面文章再講。
二、cas客戶端配置（cas-client）
1、web.xml方式配置
plsql連接oracle配置、寫了個簡單客戶端配置，源碼cas_client_test_demo.zip
