Java中的多线程回显服务器怎么利用Socket实现

Java中的多线程回显服务器怎么利用Socket实现？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

具体如下：

需要两个类，一个是EchoServer，代表服务器。另外一个是EchoServerClient，代表客户端。代码如下：

package interview;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.ServerSocket;import java.net.Socket;public class EchoServer {  public static void main(String []args) throws IOException{    ServerSocket server = new ServerSocket(6789);    while(true){      Socket client = server.accept();      ClientHandler handler = new ClientHandler(client);      new Thread(handler).start();    }  }  public static class ClientHandler implements Runnable{    private Socket client;    @Override    public void run() {      InputStreamReader isr = null;      try {        isr = new InputStreamReader(client.getInputStream());        BufferedReader br = new BufferedReader(isr);        PrintWriter pw = new PrintWriter(client.getOutputStream());        String msg = br.readLine();        System.out.println("收到" + client.getInetAddress() + "发送的" + msg);        pw.println("收到了你发的" + msg);        pw.flush();      } catch (IOException e) {        e.printStackTrace();      }    }    public ClientHandler(Socket client){      this.client = client;    }  }}
