返回信息流大家好，我java不好（说实话，软硬件都不太好），但近期做关于毕设方面的东西，我从客户端可以接受到图片流，但却不能显示出来（播放），只显示最后一张，听别人说是缓存问题，但还不知如何解决，恳请大家帮忙！代码如下：
客户端：package paper;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;

class J_Panel extends JPanel {
/**

private static final long serialVersionUID = 1L;
BufferedImage CaptureScreen0;
String ServerIp;
int ServerPort;
String m;//来自主叫方的消息
public J_Panel()
{
}
protected void paintComponent(Graphics g){
int i=0;
try{
Socket s=new Socket("118.229.227.97",5000);//localhost
ObjectInputStream dataIn=new ObjectInputStream(s.getInputStream());
s.setSoTimeout(5000);
while(true){
Thread.sleep(100); //图像采集时间间隔
BufferedImage CaptureScreen=ImageIO.read(dataIn);
else
{
System.out.println("has new picture input!");
File f=new File("CaptureScreen_From_Cliet.png");
ImageIO.write(CaptureScreen, "png",f);//保存图片
g.drawImage(CaptureScreen,0, 0,1366,768,this);//显示图像
}
}
}
catch(Exception e){
System.err.println("发生异常："+e);
e.printStackTrace();
}
}
}
public class J_Client extends JFrame{
/**

private static final long serialVersionUID = 1L;
public J_Client(){
super("桌面扑捉显示");
Container c=getContentPane();
c.add(new J_Panel(),BorderLayout.CENTER);
pack();//自适应框架大小
}
public static void main (String args[]){
try
{
J_Client app=new J_Client();
app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
app.setSize(new Dimension());
app.setVisible(true);
}
catch(Exception e){
System.err.println("发生异常："+e);
e.printStackTrace();
}
}
