java tcp接受数据
Java code

import java.io.*;

import java.net.*;

public class tcpjieshou
{
    static ServerSocket ss;
    Socket socket;
    OutputStream os;
    public tcpjieshou(){
        try{
             ss=new ServerSocket(13333);
             System.out.println( "waiting   for   client   to   connect   on... "); 
        }catch(Exception e){System.out.println("端口问题");}
    }

     void tcpjieshoutest() throws SocketException, IOException
    {
    os=new BufferedOutputStream(new FileOutputStream("C:\\Users\\Administrator\\Desktop\\tcpjieshou00.rmvb"));
    System.out.println("start....");
    InputStream  socketis = null;
      byte []buff=new byte[60000];
    try{
    while(true)
    {
      socket=ss.accept();
      System.out.println(socket);
      socketis=new BufferedInputStream(socket.getInputStream());
      socketis.read(buff);
       os.write(buff);
       os.flush  
       System.out.println("jieshou");
      }
        }catch(Exception e){
            System.out.println("while:"+e);        }
   
        }
    
        public static void main(String[] args) throws SocketException, IOException {
            new tcpjieshou().tcpjieshoutest();
        }
        
    }
    


我运行这个程序结果只显示一次jieshou,说明只循环了一次,这是怎么搞的?
