How to listen for login/logout events using Spring Security in a Spring Boot application?

Question

I am trying to log messages after a successful/failed login/logout in Spring Security.

Also, I'm using Spring Boot, so there is little configuration code.

The form that I am using is auto-generated.

WebSecurityConfig.java

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
            .authorizeRequests()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().fullyAuthenticated()
                .and()
            .formLogin();

    }

    @Configuration
    protected static class AuthenticationConfiguration extends GlobalAuthenticationConfigurerAdapter {

        @Override
        public void init(AuthenticationManagerBuilder auth) throws Exception {
            auth
                .ldapAuthentication()
                .userSearchFilter("(uid={0})")
                .contextSource()
                .url("ldap://...:389/ou=...,dc=...,dc=...")
                .managerDn("cn=...,dc=...,dc=...")
                .managerPassword("...");
        }
    }
}

logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
</configuration>

My code for login success is as follows:

LoginSuccessService.java

import java.util.Date;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationListener;
import org.springframework.security.authentication.event.*;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

@Component
public class LoginSuccessService implements ApplicationListener<InteractiveAuthenticationSuccessEvent>{

    private static final Logger logger = LoggerFactory.getLogger(LoginSuccessService.class);

    @Override
    public void onApplicationEvent(InteractiveAuthenticationSuccessEvent event) {
        logger.debug("You have been logged in successfully.");
        Date loginDate = new Date();
        logger.debug("Login Time: " + loginDate.toString());
    }
}

It won't work. I get nothing in the log.

What additional code do I need to write, if any? Do I need to initialize this listener anywhere?

I also used this link as reference, but I figured I didn't need to write a publisher, as I am not writing my own class for the event.

I have also tried with AuthenticationSuccessEvent instead of InteractiveAuthenticationSuccessEvent , but same thing.

If it helps, a failed login produces the following output(expected output should include "Failed to log in" and the current date, this is a log with debug=TRUE in application.properties ):

Answer 1

The error turned out to be configuration-related.

For capturing login events, I used the objects

InteractiveAuthenticationSuccessEvent or AuthenticationSuccessEvent (logout doesn't have an implemented listener yet, you might have luck with HttpSessionEvent ).

Also, it's important to see whether or not the logger is configured to log your package; the application is not configured by default to log application messages. That is why I was not getting any output.

So, two things:

• If your package name is com.mycompany , you should add a line in your application.properties or application.yml file(usually found in <PROJ_DIR>/src/main/resources/ ; if not, create your own) for logging:

application.properties :

logging.level.com.mycompany=DEBUG/INFO/WARN/ERROR 
    #debug is lowest, error is highest

or:

application.yml :

logging:
    level:
        com:
            mycompany: DEBUG/INFO/WARN/ERROR

• If you are trying to log an outside package, log it with the debug() method or it might not show up(I used info() and I got nothing).
