    public @ResponseBody ResponseEntity<?> logout(HttpSession session){

        String userName=(String)session.getAttribute("name");
        System.out.println("name: " + userName);
        session.invalidate();

    }
Solution

  • I do not have currently any Spring projects near me, but as I remember, it could be possible to do it like this:

    SecurityContextHolder.getContext().getAuthentication().getPrincipal();

    As I said, I'm not sure if it's working. It's been a while since I last used Spring, but let me know if it is.
