我是Spring Security的新手.如何添加事件监听器，当用户成功登录时将被调用?另外，我需要在此侦听器中获得某种唯一的会话ID，该ID可以在以后使用.我需要该ID才能与另一台服务器同步.

I'm new to Spring Security. How do I add an event listener which will be called as a user logs in successfully? Also I need to get some kind of unique session ID in this listener which should be available further on. I need this ID to synchronize with another server.

推荐答案

您需要定义一个实现 ApplicationListener .

然后，在您的代码中，执行以下操作:

Then, in your code, do something like this:

public void onApplicationEvent(ApplicationEvent appEvent) { if (appEvent instanceof AuthenticationSuccessEvent) { AuthenticationSuccessEvent event = (AuthenticationSuccessEvent) appEvent; UserDetails userDetails = (UserDetails) event.getAuthentication().getPrincipal(); // .... } }

然后，在您的applicationContext.xml文件中，只需定义该bean，它将自动开始接收事件:)

Then, in your applicationContext.xml file, just define that bean and it will automatically start receiving events :)
