Spring security:添加“成功登录事件监听器" [英] Spring security: adding "On successful login event listener"
问题描述
我是 Spring Security 的新手.如何添加将在用户成功登录时调用的事件侦听器?此外,我需要在此侦听器中获得某种唯一的会话 ID,该 ID 应该可以进一步使用.我需要此 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
你需要定义一个 Spring Bean 来实现 ApplicationListener.
You need to define a Spring Bean which implements 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,它就会自动开始接收事件 :)
Then, in your applicationContext.xml file, just define that bean and it will automatically start receiving events :)
