Question

我的Web应用程序使用spring security在登录时对用户进行身份验证。我还有并发控制，以避免用户在不同的机器上登录两次。这工作正常但我的问题是：如果用户在计算机上登录，则关闭浏览器。然后他重新打开网络应用程序，尝试再次登录，他获得以下消息：“超出此主数的最大会话数为1”。我想在浏览器关闭时使会话无效。我怎么能这样做？

为 "/" （首页）请求和 logout 请求添加以下代码。

@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");
    }
}
