即时通信

我们使用了Socket编程（套接字编程）

服务器

创建ServerSocket

等待客户端的连接

Socket s =ss.qccpet();

客户端

Soket s = new Socket();

原理图：

服务端：
Server

public class Server {    // 记录所有的客户端    private List<ThreadClient> list = new ArrayList<ThreadClient>();    // 启动服务器    public void start() throws Exception {        // 创建一个服务器        final ServerSocket serverSocket = new ServerSocket(8809);        System.out.println(serverSocket.getLocalPort());System.out.println(serverSocket.getInetAddress().getHostAddress());        // 开线程去反馈给用户的信息        new Thread(new Runnable() {            @Override            public void run() {                // 开启循环接受客服端反馈的信息                while (true) {                    try {                        // 得到客户端反馈的信息                        Socket socket =serverSocket.accept();                        // 取出客户的信息                        ThreadClient client = new ThreadClient(socket);                        System.out.println("ip:"+client.ip+",port:"+client.port);                                                /**自定义通信协议                         * 服务器通知用户刷新列表，                         * 用户上线 refresh:                         * 关键字 name:上线的ip地址                         * port:上线的端口                         * refresh@name@port                         */                        // 告诉别人我上线了                        // 通知之前上线的人                        /**                         *  迭代所有客户端：发送消息给每一个客户端                         *  c:之前上线的用户（别人）                         */                        for (ThreadClient c : list) {                            String msg = "refresh@" +client.ip+ "@" +client.port;                            c.sendMessge(msg);                        }                        // 上线后得到上线的人                        // 自己上线之后，也要知道之前上线的人                        for (ThreadClient c : list) {                            String msg = "refresh@" +c.ip+ "@" +c.port;                            client.sendMessge(msg);                        }                                                list.add(client);                    } catch (Exception e) {                        // TODO: handle exception                    }                }            }        }).start();    }    public static void main(String[] args) {        Server server = new Server();        try {            server.start();        } catch (Exception e) {            // TODO Auto-generated catchblock            e.printStackTrace();            System.out.println("启动失败");        }            }}

ThreadClient：
