java通过控制鼠标实现屏幕广播

在java实现屏幕共享的小程序中提到截取屏幕时是没鼠标，为了看到教师端界面上的鼠标，可以在截取屏幕的时候，把鼠标绘制到每一张截图上去，但是由于截图的时候是一张张截取的，所以看到的鼠标难免会有点卡，之前写了java鼠标操控小程序，可以通过这种方式来看到鼠标的演示。

实现的方式也挺简单的，前面两篇文章分别实现了鼠标控制和不带鼠标的屏幕分享功能，把这两个结合一下就ok了，下面简单分析下。

服务端，将SendScreenImg和SendMouseMessage看作两个工具类，分别监听不同的端口，他们两个都实现了Thread类，我们用线程池ExecutorService类控制他们。

使用了两个端口，因为暂时还不知道该如何吧鼠标信息和图片的信息一起发送，或许可以把图片转换成字节数组的形式，把鼠标的坐标放在数组前面，不过这样的话鼠标可能也会不连贯，因为传送鼠标坐标的速度会比传图片的要快一些，嗯，有空再试试。

客户端类比上面就是了。

下面是代码：

服务端：

主程序：

/* * 屏幕广播类，调用了两个工具类：发送截屏信息的类和发送鼠标的信息类，利用了线程池。 */public class BroderCast {public  static void main(String[] args){new BroderCast();System.out.PRintln("开始");}public BroderCast(){ExecutorService exector = Executors.newFixedThreadPool(2);exector.execute(new SendScreenImg());exector.execute(new SendMouseMessage());}}

发送鼠标信息：

/* * 工具类：获取鼠标的信息并且发送给学生端 */public class SendMouseMessage extends Thread{private int OperaTE_PORT = 8001;private ServerSocket server;private Socket socket;private String operateStr;public static void main(String[] args){new SendMouseMessage().start();}public SendMouseMessage(){try {server = new ServerSocket(OPERATE_PORT);//JOptionPane.showMessageDialog(null, "已经开始监听");} catch (IOException e1) {e1.printStackTrace();}}//多线程  在无线的循环中监听客户端的public void run(){while(true){Point point = MouseInfo.getPointerInfo().getLocation();  //operateStr ="Movemouse,"+point.x+","+point.y;try {socket = server.accept();socket.setSoTimeout(1000000);DataOutputStream output =new DataOutputStream(socket.getOutputStream());output.write(operateStr.getBytes());output.flush();   //刷行输出流，并且使所有缓冲的输出字节写出output.close();   //关闭输出流且释放资源System.out.println("INFO：  "+operateStr);} catch (IOException e) {System.out.println("已经停止连接");break;   //断开连接的时候就停止无线循环}}}}
