在eclipce项目下有个 images/images/2.gif 文件 , 先启动Service端, 跟着启动Client端发送图片,等十几秒后图片就会显示出来, 但是问题是,图片显示出来不是很完整, 有点小问题 ,希望大侠们看下咯
Service端

public class Server {
private int port = 1220;
private DatagramSocket socket;
public static File newfile = null;
public Server() throws SocketException{
socket = new DatagramSocket(port);
socket.setSoTimeout(10000);
}
public void reciveData() throws FileNotFoundException{
newfile = new File("liangliang.gif");
byte[] buf = new byte[8192];
FileOutputStream fos = new FileOutputStream(newfile);
while(true){
DatagramPacket packet = new DatagramPacket(buf, 8192);
try{
socket.receive(packet);
fos.write(packet.getData(), 0, packet.getLength());
}catch(Exception e){
try {
System.out.println("传输结束");
socket.close();
fos.flush();
fos.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
break;
}
}
}
public static void main(String[] args) throws FileNotFoundException, SocketException {
new Server().reciveData();
JFrame jf = new JFrame();
JPanel jp = new JPanel();
Image fd = new ImageIcon(newfile.getAbsolutePath()).getImage();
JLabel jl = new JLabel(new ImageIcon(newfile.getAbsolutePath()));
jf.add(jl);

jf.setVisible(true);
}
}
