how to correctly logout user in spring security

Question

Edit - 1

<security:logout
    invalidate-session="true"
    logout-success-url="/logout"
    logout-url="/logoutfail"/>

 </security:http>

Edit - 1 end http://pastie.org/8588538 are the lines 1 to 6 a correct way to logout users? because when I do, the user seems to be logged out momentarily on the page but then can visit other pages again with the same login. it seems line 31 and 38 is making a new session cookie. but how?

@RequestMapping(value = "/logout" )
    public String logout(ModelMap model, HttpServletRequest request){
        request.getSession(true).invalidate();
        System.out.println("logout user page shown--------------------");
        return "/login/logout";       
   }

This is how you do it:

SecurityContextHolder.getContext().setAuthentication(null);

Spring Security also comes with login/logout functionality already implemented, here is how you can configure a custom logout URL. You don't have to create any controllers/request mappings then.
