Java服务器multithreading

如何在Java中实现multithreading服务器？ 服务器侦听端口（例如5000）并在单独的线程中提供连接并继续侦听更多客户端的位置。

这是一个典型的例子：

ServerSocket ss = new ServerSocket(port); ExecutorService executor = Executors.newCachedThreadPool(); while(true) { Socket s = ss.accept(); Runnable r = new TaskImplementsRunnable(s); executor.submit(r) } 

 public class TaskImplementsRunnable implements Runnable { private Socket socket; public TaskImplementsRunnable(Socket socket) { this.socket = socket; } @Override public void run() { try { PrintWriter writer = new PrintWriter(socket.getOutputStream(), true); BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream())); String command; while((command = reader.readLine()) != null) { if(command.equalsIgnoreCase("command 1")) { writer.println("This is command 1!"); } else if(command.equalsIgnoreCase("command 2")) { writer.println("This is command 2!"); } else if(command.equalsIgnoreCase("exit")) { break; } else { writer.println("This is unknown command!"); } } } catch(IOException e) { e.printStackTrace(); } try { writer.close(); reader.close(); } catch(IOException e){} } }
