Java防锁屏小程序 IT

为防止系统桌面自动锁屏，只需打成jar包，写个批处理程序start.bat，双击执行保持dos窗口执行即可，无其他影响。

程序设计为每30秒动一次鼠标，可根据需要调整。

附代码：

package main;

import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.MouseInfo;
import java.awt.Point;
import java.awt.PointerInfo;
import java.awt.Robot;
import java.awt.Toolkit;

public class Main {
    public static void main(String[] args) {
        Robot robot = null;
        try {
            robot = new Robot();
        } catch (AWTException e1) {
            e1.printStackTrace();
        }
        Point pos = MouseInfo.getPointerInfo().getLocation();

        int last_x = pos.x;
        int last_y = pos.y;

        int mov = 1;

        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

        System.out.println("Screen size: " + screenSize.getWidth() + "*" + screenSize.getHeight());
        while (true) {
            System.out.println(pos.x + " " + pos.y);
            PointerInfo pos_info = MouseInfo.getPointerInfo();
            if (pos_info == null) {
                System.out.println("Get location fail!");
                try {
                    Thread.sleep(30000L);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

            } else {
                pos = pos_info.getLocation();

                if ((pos.x == last_x) && (pos.y == last_y)) {
                    System.out.println("moving!");

                    if (pos.y <= 0) {
                        mov = 1;
                    }
                    if (pos.y > 0) {
                        mov = -1;
                    }
                    robot.mouseMove(pos.x, pos.y + mov);

                    robot.mouseMove(pos.x, pos.y);
                }
                pos_info = MouseInfo.getPointerInfo();
                if (pos_info == null) {
                    System.out.println("Get location fail!");
                    try {
                        Thread.sleep(30000L);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

                } else {
                    pos = pos_info.getLocation();

                    last_x = pos.x;
                    last_y = pos.y;
                    try {
                        Thread.sleep(30000L);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }
    }
}

将这个Main类打成jar包，此处jar包名为MouseMove.jar；与jar包同目录位置写个.bat类型文件，文件内容如下：

@echo off
java -jar MouseMove.jar

双击执行即可。
