java - How to log out automatically with Spring Security

Question

I have a spring web application and I did user authentication using Spring security.

Everything works well. Log in and Log out works perfect!

Now, I want to implement in order to log out automatically. For example, if user has a window opened for about 30 minutes and do nothing (Sessions expired for instance) system should log out automatically. How can I implement this?

It might be implemented by client side (I send requests every 1 minutes and check if session is ended). But can't I do this automatically from Spring?

I have this config:

<http auto-config="true" use-expressions="true">


        <intercept-url pattern="/admin**" />
        <access-denied-handler error-page="/403" />

        <form-login login-page="/login" 
            default-target-url="/admin"
            authentication-failure-url="/login?error" 
            username-parameter="NAME"
            password-parameter="PASSWORD"  />

        <logout invalidate-session="true" 
             logout-success-url="/login?logout"/>

    </http>

and in web.xml

<session-config>
  <session-timeout>1</session-timeout>
</session-config>

after 1 minute, I see that session was destroyed. kill the session after 1 minute. but page was not redirected to /login?logout

How about to use security configuration.?? I hope below config: will work.

applicationContext.xml

 --namespace-> xmlns:security="http://www.springframework.org/schema/security"

        <security:logout invalidate-session="true"
                        success-handler-ref="Logout"
                        logout-url="/logout.html" />
        </security:http>

web.xml

 <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>

And them, you need to write your own because success-handler-ref="Logout" is custom handler for logout:
Logout @Component

public class Logout extends SimpleUrlLogoutSuccessHandler {

    @Override
    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws IOException, ServletException {

        if (authentication != null) {
            // do something 
        }

        setDefaultTargetUrl("/login");
        super.onLogoutSuccess(request, response, authentication);       
    }
}
