1.自己测试

import java.awt.AWTException;
import java.awt.Robot;

/**
 * 简单模拟鼠标移动
 *
 */
public class Client {
	public static void main(String[] args) throws AWTException, InterruptedException {
		Robot robot = new Robot();
		int i = 0;
		
		while(i<30)
		{
			robot.mouseMove(100+(i*100), 200+(i*100));
			robot.mouseWheel(20);
			i++;
			Thread.sleep(100l);
		}
	}
}

2.各种功能测试类

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;

    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("screenRect1.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);

        }
    }
