【问题描述】：
我制作了一个程序，在我单击时模拟 Robot 类的单击。所以我有 2 次点击，但我点击了一次。我的问题是 MouseListener 还检测到来自机器人的点击，并且机器人总是触发 MouseListener 并且它不会停止点击。有人知道如何解决这个问题吗？ 我使用 JNativeHook 库，所以我可以收听全局 KeyStrokes。使用 java.awt.MouseListener 我只能在窗口处于焦点时检测鼠标输入。 这是我的代码：

我已经有一段时间没有使用这个了。
getSource()方法可以帮助您区分您的点击和 java.awt.Robot 的点击吗？如果没有，您将需要一种解决方法。就像使用左键单击自己并使机器人始终右键单击一样。 （希望我理解正确的问题）。 -
您正在询问如何修复您的实施中的“错误”。我建议将“机器人”鼠标按下包装在对方法
invokeLater的调用中。话虽如此，我很想知道您的应用程序做了什么，导致您使用“机器人”来实现它，并且需要在桌面上的任何位置而不是在您的应用程序的JFrame中监听鼠标点击。 -
我是为 Minecraft 做的。您在 Minecraft 中的点击次数越多，您获得的击退就越少。应用程序会重复我的点击次数。
-
所以基本上你是想在Minecraft中作弊。我有一个建议。使用Key Bindings 绑定未使用的键，例如 F12，这样当您按下 F12 时，它会模拟多次鼠标点击。顺便说一句，你不需要jnativehook 来实施我的建议。
-
为什么我不需要 JNativeHook？是的，我试图在 Minecraft 中作弊，不，我不想像你说的那样做，因为我仍然想点击。
