上一节的当前的服务器只有像客户端发送数据的功能，并没有从客户端读取数据的功能，我们这一节将进行改进：

新建一个ChatManager类：

package com.test.test;import java.util.Vector;public class ChatManager {//完成类的单例：private ChatManager(){}private static final ChatManager cm=new ChatManager();public static ChatManager getChatManager(){return cm;}//完成ChatSocket线程的管理：Vector<ChatSocket> vector=new  Vector<ChatSocket>();//为当前的集合添加一个新的ChatSocket对象：public void add(ChatSocket cs){vector.add(cs);}//某一个线程可以调用下面的函数像其他客户端发送信息public void publish(ChatSocket cs,String out){for (int i = 0; i < vector.size(); i++) {ChatSocket csChatSocket=vector.get(i);//判断用于当前发送的线程就不用再接收此条信息了if(!cs.equals(csChatSocket)){csChatSocket.out(out);}}}}

修改其他类1：

package com.test.test;public class MyServerSocket {public static void main(String[] args) {new ServerListener().start();}}

2：

package com.test.test;import java.io.IOException;import java.net.ServerSocket;import java.net.Socket;import javax.swing.JOptionPane;public class ServerListener extends Thread {public void run() {try {ServerSocket serverSocket=new ServerSocket(12345);while(true){Socket socket=serverSocket.accept();JOptionPane.showMessageDialog(null,"有客户端连接到了12345端口！");ChatSocket cs=new ChatSocket(socket);cs.start();ChatManager.getChatManager().add(cs);}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

package com.test.test;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.UnsupportedEncodingException;import java.net.Socket;public class ChatSocket extends Thread {Socket socket;public ChatSocket(Socket s){this.socket=s;}public void out(String out){try {socket.getOutputStream().write(out.getBytes("UTF-8"));} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}public void run() {try {BufferedReader br=new BufferedReader(new InputStreamReader(socket.getInputStream(),"UTF-8"));String line=null;while((line=br.readLine())!=null){ChatManager.getChatManager().publish(this, line);}br.close();} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

类结构如下：

此时我们进行测试，打开三个终端，然后连接，然后输入内容，这样每一个客户端都能收到别人发送的信息：
