嗨我正在使用JNativeHook添加一个全局快捷方式到应用程序，在屏幕的右上角显示通知类型jframe。目前我的代码在Eclipse中运行时程序工作得很好。但是，导出到可运行jar文件后，应用程序崩溃。经过几次谷歌搜索后，我发现我需要在首选项中将Jar Launcher添加到安全窗格的辅助功能部分。安全和隐私与JNativeHook Mac OS X的问题
但是现在我有一个新问题。我的程序运行但不接受我的全局快捷方式（按下时没有任何反应）。有什么我做错了吗？
这是我用来添加JNativeHook和keybinds的代码。
主文件：
GlobalScreen.getInstance().addNativeKeyListener(new KeyManager());
的KeyManager：
private String periodName = new String();
@Override
public void nativeKeyPressed(NativeKeyEvent arg0) {
// TODO Auto-generated method stub
if (arg0.getKeyCode() == NativeKeyEvent.VK_5 && NativeInputEvent.getModifiersText(arg0.getModifiers()).equals(
"Ctrl")) {
