这是一个简单的基于客户端/服务器的ping/pong程序.不幸的是,IT不起作用并显示以下错误消息:

java.net.SocketTimeoutException: Read timed out
    at java.net.SocketInputStream.socketRead0(Native Method)
    at java.net.SocketInputStream.read(Unknown Source)
    at java.net.SocketInputStream.read(Unknown Source)
    at sun.nio.cs.StreamDecoder.readBytes(Unknown Source)
    at sun.nio.cs.StreamDecoder.implRead(Unknown Source)
    at sun.nio.cs.StreamDecoder.read(Unknown Source)
    at java.io.InputStreamReader.read(Unknown Source)

它停在CLIENT TASK 30行,实际上客户端没有读取服务器发送的内容.这里的代码:

服务器

package serverClient;

import java.net.*;
import java.io.*;
import java.util.concurrent.*;

public class Server {

    public static void main(String[]args){


        ExecutorService esp= Executors.newFixedThreadPool(50);
        try(ServerSocket ss= new ServerSocket(1027)){
            while(true){
                try{

                    Socket s=ss.accept();
                    Callable<Void> task=new ServerTask(s);
                    esp.submit(task);

                }
                catch(BindException be){}
                catch(ConnectException ce){}
                catch(NoRouteToHostException nrthe){}
                catch(IOException ioe){ioe.printStackTrace();}
            }
        }
        catch(Exception e){e.printStackTrace();}

    }
}

服务器任务
