使會話春季安全性無效

Question

我的Web應用程序使用Spring Security在登錄時對用戶進行身份驗證。 我還具有並發控制，以避免用戶在不同的計算機上登錄兩次。 這工作正常，但我的問題是：如果用戶在計算機上登錄，則關閉瀏覽器。 然后他重新打開Web應用程序，嘗試再次登錄，他得到以下消息“超出此主體的最大會話數為1”。 我想使瀏覽器關閉的會話無效。 我怎樣才能做到這一點？

為"/" （第一頁）請求和logout請求添加以下代碼。

@Controller
public class LoginController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView loadApp(HttpServletRequest request) {
        HttpSession session= request.getSession(false);
        SecurityContextHolder.clearContext();
        if(session != null) {
            session.invalidate();
        }

        return new ModelAndView("/car/login");
    }
}
