我正在研究一个使用Spring-Security的Spring-MVC应用程序.在登录应用程序中，我必须使用2个登录网址

I am working on a Spring-MVC application which uses Spring-Security. In the application for login I have to use 2 login url's

• /j_spring_security_check_for_person 与
• /j_spring_security_check_for_group

• /j_spring_security_check_for_person AND
• /j_spring_security_check_for_group

登录URL均针对我实现了UserDetails和userDetailsS​​ervice的数据库进行检查.要连接这两个URL进行登录，我正在使用springSecurityFilterChain.不幸的是，它不起作用.由于存在两天的时间，我遇到了这个问题，我可能会犯一些愚蠢的错误.请检查日志和xml，

Both the login url's check against the database where I have implemented UserDetails and userDetailsService. To connect these both url's for login, I am using springSecurityFilterChain. Unfortunately, it is not working. I am at this problem since 2 days, I might be making some silly mistake. Kindly check the log and xml,

如果我用下面的代码片段替换身份验证管理器代码，则不会收到错误消息，但是2个登录网址未注册:

If I replace the authentication-manager code with the below snippet, I don't get an error, but the 2 login url's are not registered :

<security:authentication-manager alias="authenticationManager"> <security:authentication-provider user-service-ref="userDetailsService"> <security:password-encoder ref="encoder"/> </security:authentication-provider> <security:authentication-provider user-service-ref="groupDetailsService"> <security:password-encoder ref="encoder"/> </security:authentication-provider> </security:authentication-manager>-->

推荐答案

authenticationManagerForPersonal和authenticationManagerForGroup的类型为ProviderManager.这是错误的.您必须将这些bean声明为DaoAuthenticationProvider类型. 请仔细查看我的 spring security 配置.

authenticationManagerForPersonal and authenticationManagerForGroup are of bean type ProviderManager. This is wrong. You have to declare those beans as type DaoAuthenticationProvider. Please take a closer look at my spring security configuration.
