SpringSecurity AuthenticationSuccessEvent ve AbstractAuthenticationFailureEvent Sınıfları

Giriş

Şu satırı dahil ederiz. Bu event'ler SpringSecurity tarafından otomatik yayınlanır.

import org.springframework.security.authentication.event.AbstractAuthenticationFailureEvent;
import org.springframework.security.authentication.event.AuthenticationSuccessEvent;

Açıklaması şöyle. 

Spring Security provides both Authentication Events and Authorization Events, although the latter is not typically used and is not published by default if you need to use them then you would need to inform to the Spring Security to publish them by creating an event publisher. However, the Authentication Success Event is published whenever a user is successfully authenticated and added to the Security Context.
