How to enable session and set session timeout in Spring Security

by

If you are using JavaConfig and do not want to use XML you can create a HttpSessionListener and use getSession().setMaxInactiveInterval(), then in the Initializer add the listener in onStartup():

public class SessionListener implements HttpSessionListener {

    @Override
    public void sessionCreated(HttpSessionEvent event) {
        System.out.println("session created");
        event.getSession().setMaxInactiveInterval(15);
    }

    @Override
    public void sessionDestroyed(HttpSessionEvent event) {
       System.out.println("session destroyed");
    }
}

Then in the Initializer:

@Override
public void onStartup(ServletContext servletContext) throws ServletException {
    super.onStartup(servletContext);
    servletContext.addListener(new SessionListener());
}
