Moving Spring Security To Java Config, where does authentication-success-handler-ref go?

Question

Our app has a custom success handler for successful logins. It basically redirects them to the page they were on when their session expired.

We're moving to a Java config rather than a spring xml config. The rest of the config went very smoothly, but we can't find where to put the authentication-success-handler-ref attribute of the security:form-login tag.

<security:http auto-config='true'>
  ...
  <security:intercept-url pattern="/**" access="IS_AUTHENTICATED_FULLY"/>
  <security:form-login login-page="/login" default-target-url="/sites"
                     authentication-failure-url="/login"
                     authentication-success-handler-ref="authenticationSuccessHandler"/>
 ...

Here's our config, so far.

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
       .authorizeRequests()
          .anyRequest().authenticated()
          .and()
        .formLogin()
          .loginPage("/login")
          .failureUrl("/login")
          .and()
        .logout()
          .permitAll()
          .and()
  }

Also, we can't find where to put default-target-url, but that is definitely less important.

Caveat, we're actually using Groovy, but the code is basically the same as a Java config.

Answer 1

All settings can be done inside the global configure method. Add the following:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
          .anyRequest().authenticated()
          .and()
        .formLogin()
          .loginPage("/login")
          .defaultSuccessUrl("/sites")
          .failureUrl("/login")
          .successHandler(yourSuccessHandlerBean) // autowired or defined below
          .and()
        .logout()
          .permitAll()
          .and()
  }

You have to create bean extending SimpleUrlAuthenticationSuccessHandler or SavedRequestAwareAuthenticationSuccessHandler. For example:

@Bean
public SavedRequestAwareAuthenticationSuccessHandler successHandler() {
    SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
    successHandler.setTargetUrlParameter("/secure/");
    return successHandler;
}

Then you have to setup it on bean extending AbstractAuthenticationProcessingFilter:

UsernamePasswordAuthenticationFilter authenticationFilter = new UsernamePasswordAuthenticationFilter();
authenticationFilter.setAuthenticationSuccessHandler(successHandler());
