Question

I want to prepare some data after user login system. After some google, I implemented a ApplicationListener to listen AuthenticationSuccessEvent:

import org.springframework.context.ApplicationListener;
import org.springframework.security.authentication.event.AuthenticationSuccessEvent;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Component;

    @Component
    public class MyApplicationListener implements
            ApplicationListener<AuthenticationSuccessEvent> {

        @Override
        public void onApplicationEvent(AuthenticationSuccessEvent event) {
            UserDetails userDetails = (UserDetails) event.getAuthentication()
                    .getPrincipal();
            System.out.println("Successed login:" + userDetails.getUsername());

        }

    }

I updated to Spring 3.0 RELEASE, and Spring Security 3.0.0.RC2. But I can never get called for AuthenticationSuccessEvent:( (I tried other event, such as AuthenticationFailureBadCredentialsEvent, it worked).

I use my own authentication-manager and do nothing about the event:

Do I need to podcast the event by myself?

Thank you.

You don’t specify the details of your configuration. You state that you use your own authentication-manager – does this mean you are configuring the ProviderManager explicitly using Spring Bean configuration?

If so, you need to configure the AuthenticationEventPublisher on the ProviderManager, as the default implementation is a null implementation, which doesn’t publish events.

The bean declaration for the default implementation is like this:

<bean id="defaultAuthEventPublisher" class="org.springframework.security.authentication.DefaultAuthenticationEventPublisher"/>

You’ll then need to map this bean to the appropriate property on the ProviderManager:

If you aren’t declaring your own ProviderManager, unfortunately there is not a way to enable this functionality using the security namespace style of configuration. Hope that answers your question!
