1、组播实现UDP远程桌面组播实现UDP远程桌面 服务端：packagemultiCast;importjava.awt.Dimension;importjava.awt.Graphics2D;importjava.awt.Rectangle;importjava.awt.RenderingHints;importjava.awt.Robot;importjava.awt.Toolkit;importjava.awt.image.BufferedImage;importjava.io.ByteArrayOutputStream;importjava.net.DatagramPacket;impor

2、tjava.net.InetAddress;importjava.net.MulticastSocket;importjavax.imageio.ImageIO;publicclassMultiCastServerextendsThread{   privatestaticintportTem=9999;// 端口号   privatestaticStringmutiAddr="230.0.0.1";// 组播IP地址   privateInetAddressinetAddress;// 组播消息的目标地址，及发送人的地址   privateMulticastSocketmulticastSo

3、cket;// 组播发送端套接字   privateRobotrobot;//robot用于获得本地图片   publicMultiCastServer(){       try{          inetAddress=InetAddress.getByName(mutiAddr);// 从组播地址中获得具体的发送者的地址          multicastSocket=newMulticastSocket();       }catch(Exceptione){          e.printStackTrace();          //TODO:handleexception 

4、      }   }   publicvoidrun(){       Dimensionsize=Toolkit.getDefaultToolkit().getScreenSize();// 获得屏幕大小       Rectanglerec=newRectangle(0,0,(int)size.getWidth(),(int)size              .getHeight());// 画一个窗体       try{          while(true){              // 抓取一张屏幕图片              robot=newRobot();    

5、          BufferedImageimage=robot.createScreenCapture(rec);// 把屏幕图片放入BufferedImage中              BufferedImagelittleimage=resize(image,600,500);              ByteArrayOutputStreambout=newByteArrayOutputStream();// 定义一个比特数组输出流，用来发送上面获得的图片        ImageIO.write(littleimage,"jpeg",bout);// 调用ImageIO把  

6、                                        // 图片以JPEG的形式写入到bout输出流中                       byte[]b=bout.toByteArray();// 获得bout里的数据字节，放入b中                             /*out.writeInt(b.length);// 用DataOutputStreamout发送图片大小              out.write(b);// 把图片字节写入out中              out.flush();// 刷新     */    

7、                     DatagramPacketdp=newDatagramPacket(b,b.length,inetAddress,portTem);//设置发送包的长度和端口              multicastSocket.send(dp);                                            Thread.sleep(100
