Java基础之使用多线程处理多客户端请求

 Myserver2.java:

package socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class Myserver2 {
	public static void main(String[] args) throws IOException{
		
		try {
			 ServerSocket serverSocket = new ServerSocket(8888);
			 while(true){
				 Socket socket = serverSocket.accept();
				 ServerThread serverThread = new ServerThread(socket);
				 serverThread.start();
			 }


		} catch (Exception e) {
			// TODO: handle exception
		}
	}
}

　　ServerThread.java:

package socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.ObjectInputStream;
import java.io.OutputStream;
import java.net.Socket;

public class ServerThread extends Thread{
	
	Socket socket ;
	public ServerThread(Socket socket){
		this.socket = socket;
	}
	
	
	@Override
	public void run() {
		try {
			InputStream in = socket.getInputStream();
			BufferedReader reader = new BufferedReader(new InputStreamReader(in));
	        String info = null;
	        while((info = reader.readLine())!=null){
	        	System.out.println("I am server! 接收到的客户端消息："+info);
	        }
	        socket.shutdownInput();
	        OutputStream out = socket.getOutputStream();
	        out.write("已收到！！！...".getBytes());
	        socket.shutdownOutput();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

　　Myclient1.java:

package com.example.demo;

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;

public class Myclient {
    public static void main(String[] args) {
        try {
            Socket socket = new Socket("localhost",8888);
            System.out.println("客户端1启动");
            OutputStream out = socket.getOutputStream();
            out.write("hello socket!".getBytes());
            socket.shutdownOutput();
            InputStream input = socket.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(input));
            String info = null;
            while((info = reader.readLine())!=null){
                System.out.println("I am client1! 接收到的服务端端消息："+info);
            }
            socket.shutdownInput();
        } catch (Exception e) {
            // TODO: handle exception
        }
    }
}

　　多创建几个client。运行看结果：
