cas-server-3.5.2系統需要集成下面的jar包：
cas-server-integration-restlet-3.5.2.jar
com.noelios.restlet.ext.servlet-1.1.10.jar
com.noelios.restlet.ext.spring-1.1.10.jar
com.noelios.restlet-1.1.10.jar
org.restlet.ext.spring-1.1.10.jar
org.resetlet-1.0.jar
登錄過程：
根據用戶名、密碼首先獲取TGT（Ticket Granting Ticket）；
然後根據返回的TGT獲取ST（Service Ticket）；
根據獲取的ST登錄需要訪問的系統，系統url?ticket=ST。
