Java中的多个客户端到服务器通信程序 [英] Multiple client to server communication program in Java

问题描述

我写了一个服务器 - 客户端通信程序，它运行良好。

I wrote a server-client communication program and it worked well.

import java.io.*;
import java.net.*;

class Client {
    public static void main(String argv[]) throws Exception {
        String sentence;
        String modifiedSentence;
      while(true){
        BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));

        Socket clientSocket = new Socket("myname.domain.com", 2343);

        DataOutputStream out = new DataOutputStream(clientSocket.getOutputStream());
        BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

        System.out.println("Ready");
        sentence = in.readLine();
        out.writeBytes(sentence + '\n');
        modifiedSentence = in.readLine();
        System.out.println(modifiedSentence);
       }
      clientSocket.close();
    }
}

服务器模块

Server module

import java.net.*;

public class Server {
    public static void main(String args[]) throws Exception {
        String clientSentence;
        String cap_Sentence;
        ServerSocket my_Socket = new ServerSocket(2343);

        while(true) {
            Socket connectionSocket = my_Socket.accept();
            BufferedReader in = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
            DataOutputStream out = new DataOutputStream(connectionSocket.getOutputStream());
            clientSentence = in.readLine();
            cap_Sentence = "Raceived:" +  clientSentence + '\n';
            out.writeBytes(cap_Sentence);
        }
    }
}

以上是代码单个客户端 - 服务器通信，现在我希望多个客户端与该服务器进行交互。我搜索了它，发现它可以通过使用一个线程为每个单个客户端与服务器通信来完成，但由于我是初学者，我不知道具体如何实现。所以有人请告诉我该怎么做或给我一些想法。

The above is the code for a single client - server communication, now I want multiple client to interact with that server. I googled for it and found that it can be done with the use of a thread for each single client to talk to the server, but since I am a beginner I don't know exactly how to implement. So somebody please tell me how to do or give me some idea about it.

推荐答案

MainServer类

MainServer class

public class Server {

    public static void main(String[] args) throws IOException {

        ServerSocket serverSocket = null;

        boolean listeningSocket = true;
        try {
            serverSocket = new ServerSocket(2343);
        } catch (IOException e) {
            System.err.println("Could not listen on port: 2343");
        }

        while(listeningSocket){
            Socket clientSocket = serverSocket.accept();
            MiniServer mini = new MiniServer(clientSocket);
            mini.start();
        }
        serverSocket.close();       
    }

}

助手类

public class MiniServer extends Thread{

    private Socket socket = null;

    public MiniServer(Socket socket) {

        super("MiniServer");
        this.socket = socket;

    }

    public void run(){
            //Read input and process here
    }
            //implement your methods here

}
