Socket 编程
在Socket编程 - 单个客户端中，服务端只支持单个客户端的连接请求。如果有多个客户端连接呢？需要有一个线程一直监听客户端请求，收到请求后分发给其它的线程处理。这和jetty的处理方式类似。只需要改动服务端的代码就可以了。
服务端：
public class MyMultiClientsServer {private static final int SERVER_PORT = 4451;ServerSocket server;Socket socket;public MyMultiClientsServer() {try {server = new ServerSocket(SERVER_PORT);while (true) {socket = server.accept();new DispatchRequestThread(socket).start();}} catch (IOException e) {e.printStackTrace();} finally {// Release the resources opened}}class DispatchRequestThread extends Thread {BufferedReader in;PrintWriter out;Socket socket;public DispatchRequestThread(Socket socket) {this.socket = socket;}@Overridepublic void run() {try {in = new BufferedReader(new InputStreamReader(socket.getInputStream()));out = new PrintWriter(socket.getOutputStream(), true);while (true) {String str = in.readLine();System.out.println(socket.getPort() + ": " + str);out.println("Received: " + str);if (str.equals("end"))break;}} catch (IOException e) {e.printStackTrace();} finally {// Release the resources opened}}}public static void main(String[] args) {new MyMultiClientsServer();}}
开启服务端后，开启多个服务端进行测试, 结果如下：
3014: hello
3015: signature
3014：end
