解决方案

如果您可以让浏览器（可靠地）通知服务器，窗口，那么服务器可以根据ejay_francisco提供的原始答案调用 session.invalidate（）。

难以让通知可靠地发生。有很多方法可以检测窗户关闭;例如（以及类似的）：

• 尝试检测浏览器关闭事件


• javascript来检查浏览器窗口关闭时间


• 检测浏览器关闭标签页/关闭浏览器

然后，您可以编写（javascript）关闭事件处理程序向服务器发送特定请求。

但是，不要以为任何方案都能够处理用户浏览器死亡，用户机器关闭以及类似情况的情况。所以，如果你需要在100％的时间内清除会话，那么你可能不是很幸运。我认为不能这样做。

解决方案

If you could get the browser to (reliably) notify the server that the user had closed the window, then the server could call session.invalidate() as per the original Answer provided by ejay_francisco.

The difficulty is getting the notification to happen reliably. There are various ways to detect the window close; e.g. as covered by these Questions (and similar):

• Trying to detect browser close event
• javascript to check when the browser window is close
• javascript detect browser close tab/close browser

You could then write the (javascript) close event handler to send a specific request to the server.

However, I don't think any scheme is going to be able to deal with cases where the user's browser dies, the user's machine is shut down, and similar scenarios. So if you need the session to be cleared 100% of the time, then you are probably out of luck. I don't think it can be done.
