第一个例子创建了一个java工程,用来测试Socket的连接功能,通过浏览器可访问,地址为:127.0.0.1:端口号

 MyServerSocket.java,

package com.jikexueyuan.testmysetversocket.main;


public class MyServerSocket {

    public static void main(String[] args) {
        new ServerListener().start();
        
    }

}

 

ServerListener.java

 1 package com.jikexueyuan.testmysetversocket.main;
 2 
 3 import java.io.IOException;
 4 import java.net.ServerSocket;
 5 import java.net.Socket;
 6 
 7 import javax.swing.JOptionPane;
 8 
 9 public class ServerListener extends Thread {
10 
11     @Override
12     public void run() {
13         //1-65535
14         try {
15             ServerSocket serverSocket = new ServerSocket(12345);
16             while (true) {
17                 //block
18                 Socket socket = serverSocket.accept();
19                 //建立连接
20                 JOptionPane.showMessageDialog(null, "有客户端链接到了本机的12345端口");
21                 //将socket传递给新的线程
22                 ChatSocket cs = new ChatSocket(socket);
23                 cs.start();
24                 ChatManager.getChatManager().add(cs);
25             }
26             
27         } catch (IOException e) {
28             e.printStackTrace();
29         }
30     }
31 }

20         try {

40                 System.out.println(line);
41                 ChatManager.getChatManager().publish(this, line);
