这样就可以实现图像通过ObjectInputStream和ObjectOutputStream的串行化传播了

了解了以上基础之后首先我们要完成控制端的UI界面设置，图片接收，和键盘鼠标动作监听：

首先是设置接收图片：

public static void reveivePic() throws ClassNotFoundException, IOException{
 Message g = (Message)OIS.readObject();
 FileOutputStream FOS = new FileOutputStream("D:\\OUT\\"+g.getFileName());
 FOS.write(g.getFileContent(),0,(int)g.getFileLength());
 FOS.flush();

 FileInputStream FIS= new FileInputStream("D:\\OUT\\"+g.getFileName());
 BufferedImage BI = ImageIO.read(FIS);
 IIC=new ImageIcon(BI);

 Image img = IIC.getImage();
 Toolkit tk = Toolkit.getDefaultToolkit() ;
  Dimension d =tk.getScreenSize();

  int w = d.width;
  int h =d.height;
  BufferedImage bi = resize(img,800,600);


  imag_lab.setIcon(new ImageIcon(bi));
  imag_lab.repaint();//销掉以前画的背景
 }

 private static BufferedImage resize(Image img, int newW, int newH) {
  int w = img.getWidth(null);
  int h = img.getHeight(null);
  BufferedImage dimg = new BufferedImage(newW, newH,BufferedImage.TYPE_INT_BGR);
  Graphics2D g = dimg.createGraphics();
  g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
   RenderingHints.VALUE_INTERPOLATION_BILINEAR);
  g.drawImage(img, 0, 0, newW, newH, 0, 0, w, h, null);
  g.dispose();
  return dimg;
 }

这样接收了来自ObjectInputStream的Message类之后就可以把图片重新设置到面板pane的大小然后展示出来

下一步就是设置面板属性和监听器：

public static void showUI(){
 //控制台标题
  JFrame jf = new JFrame("控制台");setListener(jf);
  //控制台大小
  jf.setSize(500, 400);
  //imag_lab用于存放画面
  imag_lab = new JLabel();
  jf.add(imag_lab);
  //设置控制台可见
  jf.setVisible(true);
  //控制台置顶
  jf.setAlwaysOnTop(true);
  jf.setResizable(true);
  jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


 }

监听器:

 public static void setListener( JFrame frame){
  //panel设置监听器
  frame.addKeyListener(new KeyAdapter(){
   public void keyPressed(KeyEvent e) {
    sendEventObject(e);
   }

   @Override
   public void keyReleased(KeyEvent e) {
    sendEventObject(e);
   }

   @Override
   public void keyTyped(KeyEvent e) {

   }
 });
  frame.addMouseWheelListener(new MouseWheelListener(){
   public void mouseWheelMoved(MouseWheelEvent e) {
    sendEventObject(e); 
   }
  });
  frame.addMouseMotionListener(new MouseMotionListener(){

   public void mouseDragged(MouseEvent e) {

    sendEventObject(e);
   }

   public void mouseMoved(MouseEvent e) {


    sendEventObject(e);

   }
  });
  frame.addMouseListener(new MouseListener(){
  public void mouseClicked(MouseEvent e) {
    sendEventObject(e);

   }
  public void mouseEntered(MouseEvent e) {

    sendEventObject(e);
   }
  public void mouseExited(MouseEvent e) {

    sendEventObject(e);
   }
  public void mousePressed(MouseEvent e) {

    sendEventObject(e);
   }
 public void mouseReleased(MouseEvent e) {

    sendEventObject(e);
   }

  });
 }

 private static void sendEventObject(InputEvent event){
  try{ System.out.println("send");
  OOS.writeObject(event);
  OOS.flush();

  }catch(Exception ef){
   ef.printStackTrace();
  }
