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：
