场景

桌面管理软件会在10分钟内无操作时，自动锁屏，但由于某些特殊情况，需要防止锁屏。此时可以写一个工具，定时按下SCROLL LOCK键，此方式适用于台式机。

实现方式

代码非常简单，直接上代码

Java

import java.awt.*;
import java.awt.event.KeyEvent;public class NotLockRunner implements Runnable {private final Robot robot;private final int duration;public NotLockRunner(int duration) throws AWTException {this(new Robot(), duration);}public NotLockRunner(final Robot robot, int duration) {this.robot = robot;this.duration = duration;System.out.printf("[防锁屏线程] 初始化完成，时间间隔为 %d 秒%n", duration);}@Overridepublic void run() {while (true) {try {if (robot == null) break;Thread.sleep(duration * 1000L);robot.keyPress(KeyEvent.VK_SCROLL_LOCK);Thread.sleep(1000);robot.keyPress(KeyEvent.VK_SCROLL_LOCK);System.out.println("[防锁屏线程] 机器人按下 VK_SCROLL_LOCK 键以防止锁屏...");} catch (Exception e) {System.err.println("[防锁屏线程] 模拟按键出错："+e.getMessage());}}}public static void main(String[] args) throws AWTException {new Thread(new NotLockRunner(9*60)).start();}
}

Node.js

Node 本身没有相关的功能，可以用 robot.js、robot-cmd 、rubick-native等第三方库
