Spring security: adding “On successful login event listener”

You need to define a Spring Bean which implements ApplicationListener.

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();

        // ....
    }
}

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