《Java 核心技术 卷1》 笔记 第11章 异常、日志、断言和调试（10）Robot 模拟键盘鼠标事件

 11.6.3 AWT 的 Robot 类

Robot 类

版本：JDK 1.3+

用途：键盘、鼠标事件发送给 AWT ，自动对用户界面检测

获取屏幕设备：

GraphicsEnvironment enviroment = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice screen = environment.getDefaultScreenDevice();

Robot 对象创建:

Robot robot = new Robot(screen);

模拟键盘按下、释放：

robot.keyPress(KeyEvent.VK_TAB);

robot.keyRelease(KeyEvent.VK_TAB);

模拟鼠标移动、按下、释放：

robot.mouseMove(x, y);
robot.mousePress(InputEvent.BUTTON1_MASK);
robot.mouseRelease(InputEvent.BUTTON1_MASK);

操作间延迟：

Robot.delay(1000);

它有几个关注点：

作者给的程序本人没有跑通，开了几个EventQueue 勉强跑出来Robot 点击位置是相对位置，大概是相对于当前鼠标位置，所以只能各个系统自己调（这只能测键盘吧，测鼠标也太坑了。。。）Buttonframe 是前面好多章节的代码，大概是第 8 章（作者用旧代码此处没有表述），为了方便读者也贴在代码中了
