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

@Component
public class AuthenticationSuccessListener implements ApplicationListener<AuthenticationSuccessEvent> {

    @Override
    public void onApplicationEvent(AuthenticationSuccessEvent event) {
        Authentication authentication = event.getAuthentication();
        Object principal = authentication.getPrincipal();

        if (principal instanceof UserDetails) {
            UserDetails userDetails = (UserDetails) principal;
            // 获取用户详细信息，如用户名、密码、角色等
            String username = userDetails.getUsername();
            // 其他操作...
        }
    }
