How to manually log out a user with spring security?

Question

Probably the answer is simple: How can I manually logout the currently logged in user in spring security? Is it sufficient to call:

SecurityContextHolder.get         


        

Answer 1

Simply do like this (the ones commented by "concern you") :

    Authentication auth = SecurityContextHolder.getContext().getAuthentication(); // concern you

    User currUser = userService.getUserById(auth.getName()); // some of DAO or Service...

    SecurityContextLogoutHandler ctxLogOut = new SecurityContextLogoutHandler(); // concern you

    if( currUser == null ){
        ctxLogOut.logout(request, response, auth); // concern you
    }
