找不到JNativeHook类

Question

我需要一个KeyListener，它也可以在聚焦GUI组件之外工作，所以在进行研究之后，我遇到了JNativeHook库。但是，当我下载了ZIB文件（从这里开始）并将JNativeHook-2.1.0.Jar添加到我的Eclipse项目（属性->Java构建路径->Libraries->Add External Jar)，运行TestProgramm时就会出现错误消息。

我的程序：

package key;

import org.jnativehook.GlobalScreen;
import org.jnativehook.NativeHookException;
import org.jnativehook.keyboard.NativeKeyEvent;
import org.jnativehook.keyboard.NativeKeyListener;

public class GlobalKeyListenerExample implements NativeKeyListener {
    public void nativeKeyPressed(NativeKeyEvent e) {
        System.out.println("Key Pressed: " + NativeKeyEvent.getKeyText(e.getKeyCode()));

        if (e.getKeyCode() == NativeKeyEvent.VC_ESCAPE) {
            try {
                GlobalScreen.unregisterNativeHook();
            } catch (NativeHookException e1) {
                
                e1.printStackTrace();
            }
        }
    }

    public void nativeKeyReleased(NativeKeyEvent e) {
        System.out.println("Key Released: " + NativeKeyEvent.getKeyText(e.getKeyCode()));
    }

    public void nativeKeyTyped(NativeKeyEvent e) {
        System.out.println("Key Typed: " + e.getKeyText(e.getKeyCode()));
    }

    public static void main(String[] args) {
        try {
            GlobalScreen.registerNativeHook();
        }
        catch (NativeHookException ex) {
            System.err.println("There was a problem registering the native hook.");
            System.err.println(ex.getMessage());

            System.exit(1);
        }

        GlobalScreen.addNativeKeyListener(new GlobalKeyListenerExample());
    }
}

我也经历过同样的问题。

对我来说，解决方案是将JNativeHook.jar放在类路径中，而不是ModulePath中。
