如何使用在Windows上运行的Java服务检测用户活动？

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.InputEvent;

public class UserActivityDetector {
    public static void main(String[] args) {
        try {
            Robot robot = new Robot();
            robot.delay(5000); // 延迟5秒
            while (true) {
                robot.keyPress(KeyEvent.VK_WINDOWS); // 模拟按下Windows键
                robot.keyRelease(KeyEvent.VK_WINDOWS); // 模拟松开Windows键
                Thread.sleep(10000); // 等待10秒
            }
        } catch (AWTException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.InputEvent;

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

public class UserActivityDetector implements NativeKeyListener {
    public static void main(String[] args) {
        try {
            GlobalScreen.registerNativeHook();
            GlobalScreen.addNativeKeyListener(new UserActivityDetector());
        } catch (NativeHookException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void nativeKeyPressed(NativeKeyEvent e) {
        System.out.println("Key Pressed: " + NativeKeyEvent.getKeyText(e.getKeyCode()));
    }

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

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