Socket 编程 - 多个客户端

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;
		}
		
		@Override
		public 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
