多个客户端到服务器通信程序在java中！ [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，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);
        }
    }
}

上述代码单个客户端 - 服务器通信，现在我想要多个客户端与该服务器交互。我googled为它发现它可以做到使用线程为每个单个客户端与服务器通话，但由于我是一个初学者，我不知道如何实现。

The above is the code for 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 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();       
    }

}

帮助器类

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

}
