桌面共享的实现

#### 1.首先创建一个窗口类并对窗口的属性进行设置 ####

import org.omg.CORBA.PUBLIC_MEMBER;
    
    import javax.swing.*;
    
    public class DemoFrame extends JFrame {
        DemoPanel demoPanel=new DemoPanel();
        public DemoFrame(){
            super.setTitle("java窗口");
            super.setSize(800,600);
            super.setLocationRelativeTo(null);
            super.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            super.add(demoPanel);
            super.setVisible(true);
        }
    }

#### 2.编辑画布内容 ####

public class DemoPanel extends JPanel {
        BufferedImage image=null;
    
        public DemoPanel(){
            try {
                File file=new File("aa.png");
    
                image= ImageIO.read(file);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
        public void startServer(){
            try {
                ServerSocket serverSocket=new ServerSocket(9999);
                while(true){
                    Socket socket=serverSocket.accept();
                    InputStream inputStream=socket.getInputStream();
                    image=ImageIO.read(inputStream);
                    repaint();
                }
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
        public void paint(Graphics g){
            g.drawImage(image,0,0,image.getWidth(),image.getHeight(),null);
        }
    }

#### 3.编写服务端运行代码 ####

public class MainTest {
        public static void main(String[] args) {
            DemoFrame demoFrame=new DemoFrame();
            demoFrame.demoPanel.startServer();
        }
    }

#### 4.编写客户端代码 ####

public class MainClent {
        public static void main(String[] args) throws AWTException, IOException, InterruptedException {
            //截图
            //获取屏幕大小
            while (true){
                Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();
                //转成矩形
                Rectangle screenRenctangle=new Rectangle(screenSize);
                //机器人类
                Robot robot=new Robot();
                //截屏
                BufferedImage image=robot.createScreenCapture(screenRenctangle);
                //发送服务端
                ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
                ImageIO.write(image,"png",byteArrayOutputStream);
                //BufferedImage转成字节数组
                byte [] bytes=byteArrayOutputStream.toByteArray();
                Socket socket=new Socket("192.168.6.49",9999);
                OutputStream outputStream=socket.getOutputStream();
                //写字节数组
                outputStream.write(bytes);
                Thread.sleep(10);
            }
        }
    }

按照如下图片对客户端进行编辑生成jar文件

路劲选择之前的客户端代码

右下角先apply，再ok

将生成的jar文件发送给别人

运行服务端，接受文件的人对文件进行双击即可共享桌面。
