Java套接字仅适用于一个客户端，在服务器接受后被阻止

Question

I have a problem with my client/server program, which is blocked after one client is connected. My one client can communicate with my server, but when I try to connect another, the second can't connect. I never see my 'ok' on my console:

public class Server{
  private Map<Integer,ThreadClient > mapThreads;
  private ServerSocket serveur ;

  public static void main(String args[])
  {
    try{
      Serveur serv = new Server();
      serv.setServer( new ServerSocket(4786,2));

      while (true)
      {
        serv.getMapThreads().put(new ThreadClient(serv.getServer().accept(),serv);
        System.out.println("ok");
      }
    }
    catch (Exception e) { }
  }

class ThreadClient implements Runnable
{
  private Thread t;
  private Socket socket;
  private ObjectOutputStream oos ;
  private ObjectInputStream ois;
  private Serveur server;

  public ThreadClient(Socket s, Server serv ) throws ClassNotFoundException
  {
    server = serv;
    socket=s;
    try{
      oos = new ObjectOutputStream(socket.getOutputStream());
      ois = new ObjectInputStream(socket.getInputStream());
    }
    catch (IOException e){ }

    t = new Thread(this);
    t.start();
  }

  public void run()
  {
    try
    {
      while(true){
        // send and recev message
      }
    }
  }
  catch (Exception e){ }
}

Move the construction of the object streams out of the constructor and into the run() method. The process implies I/O with the peer so it shouldn't be carried out in the accept() thread.
