OpenJWeb平台Spring Security+CAS SSO的配置

CAS Server的搭建就不用介绍了,这里介绍一下OpenJWeb平台中Spring Security如何与CAS集成.Spring security集成CAS的官方例子可从https://src.springframework.org/svn/spring-security/trunk/samples/cas/client/src/main/webapp下载,但是这个例子过于简单,权限ID是配置在xml中,而本文介绍的配置,权限ID是存储在数据库中的.下面是配置的applicationContext-security.xml(这个配置已测通):

说明:(1)SSO认证入口为/secure/index.jsp,这个文件有个重定向语句,作用是当SSO认证通过后跳转到系统主页面.在测试过程中发现只有访问/secure目录下jsp才自动到cas server认证,sec:intercept-url 配置其他的目录不跳转到cas server进行认证,不知道是什么原因.

(2) cas server采用3.3.2版本

(3)client端为cas-client-core-3.1.3.jar
