SpringBoot中Shiro使用Pac4j集成CAS认证
SpringBoot中Shiro使用Pac4j集成CAS认证
Pac4j 简介
Pac4j与Shiro，Spring Security一样都是权限框架，并且提供了OAuth - SAML - CAS - OpenID Connect - HTTP - OpenID - Google App Engine - Kerberos (SPNEGO) 的认证集成。且可以和shiro,security等权限框架集成。
Pac4j CAS认证流程
代码 关键部分
说明: pac4j-cas与shiro的集成是通过过滤器完成cas认证，提供相应的Pac4jRealm来与shiro集成。代码过多就不一一列出了，详细的请下载附件，附件中代码屏蔽了公司相关代码。自身项目需要保持CAS与非CAS并存所以把CAS登录固定到指定路径了。

问题
- 默认配置不支持CAS登出本地项目退出
重写ShiroSessionStore见ExShiroSessionStore.java
