How I can get session object from ApplicationListener method

Question

I want to add object to HttpSession after successful user authentication. Please don\'t suggest solution with SavedRequestAwareAuthentica

As far as I am aware, ApplicationListener instances are just beans within your ApplicationContext. Therefore you should be able to inject other beans or resources into them.

So to get a reference to the current HttpSession instance:

public class AuthenticationSuccessListener implements ApplicationListener<InteractiveAuthenticationSuccessEvent> {

@Autowired
private HttpSession httpSession;

        @Override
        public void onApplicationEvent(InteractiveAuthenticationSuccessEvent e) {
               //adding object to HttpSession
        }
}

Spring will inject the HttpSession using its scoped proxy mechanism ensuring that you get the HTTPSession relevant to the current thread of execution.

You'll also need to ensure that you register a RequestContextListener in your web.xml so that Spring can inject the current HTTPSession.

<listener>  
   <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>  
</listener>
