Java使用Robot操作键盘和鼠标

Java提供操作键盘和鼠标的API，在java.awt.*包中，官方API参见此处,下面是个简单的例子：

    package com.yeetrack.robot;        import javax.imageio.ImageIO;      import java.awt.*;      import java.awt.event.InputEvent;      import java.awt.event.KeyEvent;      import java.awt.image.BufferedImage;      import java.io.File;      import java.io.IOException;        /**      * Created with IntelliJ IDEA.      * User: victor      * Date: 13-9-26      * Time: 上午10:03      */      public class RobotTest      {          public static void main(String[] args) throws AWTException,         InterruptedException, IOException          {                Robot robot = new Robot();              //设置Robot产生一个动作后的休眠时间,否则执行过快              robot.setAutoDelay(1000);               //获取屏幕分辨率              Dimension d = Toolkit.getDefaultToolkit().getScreenSize();              System.out.println(d);              Rectangle screenRect = new Rectangle(d);              //截图              BufferedImage bufferedImage =       robot.createScreenCapture(screenRect);              //保存截图              File file = new File("screenRect.png");              ImageIO.write(bufferedImage, "png", file);                //移动鼠标              robot.mouseMove(500, 500);                //点击鼠标              //鼠标左键              System.out.println("单击");              robot.mousePress(InputEvent.BUTTON1_MASK);              robot.mouseRelease(InputEvent.BUTTON1_MASK);                //鼠标右键              System.out.println("右击");              robot.mousePress(InputEvent.BUTTON3_MASK);              robot.mouseRelease(InputEvent.BUTTON3_MASK);                //按下ESC，退出右键状态              System.out.println("按下ESC");              robot.keyPress(KeyEvent.VK_ESCAPE);              robot.keyRelease(KeyEvent.VK_ESCAPE);              //滚动鼠标滚轴              System.out.println("滚轴");              robot.mouseWheel(5);                //按下Alt+TAB键              robot.keyPress(KeyEvent.VK_ALT);              for(int i=1;i<=2;i++)              {                  robot.keyPress(KeyEvent.VK_TAB);                  robot.keyRelease(KeyEvent.VK_TAB);              }              robot.keyRelease(KeyEvent.VK_ALT);            }      }
