Question

我一直在运行游戏服务器而且我收到此错误。我还不熟悉java，所以请帮帮我。我有几个活动经理来处理玩家事件，比如木刻或采矿，也许事件没有正确停止，我不确定。你能解释一下awt事件队列是什么吗？

当我们让游戏服务器运行超过一天时会发生这种情况。可能每12小时左右就会发生一次。

Answer 1

我猜你正在更新事件调度线程之外的组件状态，这可能会导致问题。

也许Concurrency in Swing会有所帮助。

Answer 2

关于事件队列：当您拥有使用图形用户界面（GUI）的应用程序时，还有一个与此GUI关联的线程。该线程运行一个循环，等待鼠标点击等事件。如果需要更改某些内容（例如，使用更多数据更新列表），该线程也应该更新GUI上的控件。

GUI线程操作来自所谓的事件队列的更改。需要更新GUI的其他线程需要将其更新转发到GUI线程，这是将它们添加到事件队列的过程，因为只有GUI线程才能实际应用它们。
