我想在Java小程序中使用Robot类来使Web浏览器移动并单击鼠标 [英] I want to use Robot class in java applet for web browser to move and click mouse

问题描述

我创建了这个applet，它将鼠标移至屏幕上的1000 pos.它可以作为应用程序使用，但不能在applet中使用.我已经创建了签名小程序，但仍然不会移动鼠标.我该怎么做才能使我的Robot类在浏览器中正常工作?我的代码如下:

I have created this applet, It moves mouse to 1000 pos on screen. It works as application but it does not work in applet. I have created signed applet but still it wont move mouse. What should I do to make my Robot class work from browser? My code is as below:

import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Robot;
import java.awt.AWTException;

public class s extends Applet {
        public void paint(Graphics g) {
            g.drawString("Test1", 10, 10);
        }

        public void init() {
                try {
                        Robot robot = new Robot();
                        robot.mouseMove(1000,50);
                        System.out.println("code executes");
                } catch (Exception ex) {
                        System.out.println("code failed");
                };
        }
}

推荐答案

单独签名不会给您的Applet任何权限.您需要向Applet授予createRobot权限.

Signing alone won't give your Applet any permissions. You need to grant the createRobot permission to your Applet.
