我正在尝试使用 CAS 和 Spring Security 在多个 Web 应用程序中实现 SSO。预期案例:
CAS - http://localhost:8080/cas/
App A 受保护内容 - http://localhost:8081/cas-client1/secure/index.html
App B 受保护内容 - http://localhost:8081/ cas-client2/secure/index.html
1)当用户访问cas-client1时,会提示CAS登录表单并触发认证。
2)同一个用户访问cas-client2,之前的登录应该可以识别,不会提示登录表单
但是,我未能执行第 2 步。CAS 登录表单仍然提示用户,因此需要双重登录。我的 Spring Security 配置中是否有任何错误设置:
<security:http entry-point-ref="casAuthenticationEntryPoint" auto-config="true">
<security:intercept-url pattern="/secure/**" access="ROLE_USER" />
<security:custom-filter position="CAS_FILTER" ref="casAuthenticationFilter" />
