PC防锁屏定时工具

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);
    }

    @Override
    public 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

Rust

三方库:enigo、redv
