Java Swing 和事件错误？

Question

我一直在运行游戏服务器并收到此错误。我对java还不是很熟悉，所以请帮帮我。 我有几个事件管理器来处理玩家事件，比如伐木或采矿，也许事件没有正确停止，我不确定。 你能解释一下什么是awt事件队列吗？

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

Answer 1

我猜你正在更新事件调度线程之外的组件状态，这可能会随机导致问题。

也许Concurrency in Swing 会有所帮助。

Answer 2

关于事件队列：当您有一个使用图形用户界面 (GUI) 的应用程序时，还有一个 与此 GUI 相关联的线程。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），该线程也是应该更新 GUI 上的控件的唯一线程。

GUI 线程从所谓的事件队列 操作更改。需要更新 GUI 的其他线程需要将其更新转发到 GUI 线程，通过该过程将它们添加到事件队列中，因为只有 GUI 线程才能实际应用它们。
