网络Socket编程（简易qq实现之C/S通信1）

1. 目标：实现两个用户之间的通信，利用的是简单的Socket知识以及简略界面

2. 界面：分为客户端与服务器端（如下图）

3. 基本功能：客户端先向服务器端发送一个消息，这样就可以让客户端与服务器端实现持续通信

4. 代码实现：

（1）服务器端代码

54         try {
55             //服务器监听端口
56             System.out.println("服务器在监听.....");
57             ServerSocket ss = new ServerSocket(9992);
58             Socket s = ss.accept();
59             //服务器接收流
60             InputStreamReader isr = new InputStreamReader(s.getInputStream());
61             BufferedReader br = new BufferedReader(isr);
62             //服务器输出
63             pw = new PrintWriter(s.getOutputStream(), true);
64             while (true) {
65                 //持续接收从客户端信息并显示
66                 String info = br.readLine();
67                 jta.append("客户端对服务器端说:"+info+"\r\n");
68             }
69         } catch (Exception e) {
70             // TODO: handle exception
71         }
72     }
73     @Override
74     public void actionPerformed(ActionEvent e) {
75         //在Jtextfield内获取文字，并发送给客户端
76         if(e.getSource()==jb){
77             String msg = jtf.getText();
78             jta.append("服务器对客户端说："+msg+"\r\n");
79             pw.println(msg);
80             jtf.setText("");
81         }
