每个 APP 使用 Tomcat JDBCRealm 进行认证 (Authentication),但使用 Spring Security 进行授权。两者基于相同的用户信息数据库。
在 Tomcat 中打开 SSO -- 这个很重要,否则访问同一个域中其它 webapp 时,不会带上 Cookie,也就无法认证了
在每个 webapp 中,配置 Web.xml 使用 Tomcat 进行认证 -- 如果用 Spring 进行认证,则 Tomcat 的 SSO 不起作用
在每个 webapp 中,配置 spring,使用 J2eePreAuthenticatedProcessingFilter,进行权限控制 (Authorization)
spring.xml 中的配置
