使会话春季安全性无效

我的Web应用程序使用Spring Security在登录时对用户进行身份验证.我还具有并发控制，以避免用户在不同的计算机上登录两次.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Web应用程序，尝试再次登录，他得到以下消息超出此主体的最大会话数为1".我想使浏览器关闭时的会话无效.我该怎么办?

My web application uses spring security to authenticate user on login. I also have concurrency control to avoid user to login twice on different machine. This is working fine but my problem is that: If user is login on a machine, then close the browser. And he reopen the web app , try to login again he gets the following msg 'Maximum sessions of 1 for this principal exceeded' . I want to invalidate the session on browser closed. How can I do this?
