如何在后台线程中启动服务器，并知道服务器在启动时没有抛出异常？ [英] How can I start a server in a background thread and know that the server did not throw exception on startup?

问题描述

我有一个封装服务器套接字的类，即服务器功能。

类的接口是：

I have a class which encapsulates a Server Socket i.e. a server functionality.
The interface of the class is:

class Server{  
  public void start();  
  public void stop();  
}

开始如下：

public void start(){  
   ExecutorService tp = Executors.newSingleThreadExecutor();  
   while(!stop){  
    try {  
        Socket clientConnection = serverSocket.accept();  
        tp.execute(new ClientProcessor(clientConnection));                
    } catch (IOException e) {  
            stop = true;
    }  
   }    

我不知道如何开始这个我的意思是我需要从后台线程启动服务器，所以我想到了以下内容：

I have trouble figuring out how I would start this without blocing my main.
I mean I need to start the server from a background thread so I thought of the following:

ExecutorService tp2 = Executors.newSingleThreadExecutor();  
 tp.submit(new Runnable(){  
     public void run(){  
    Server s = new Server();
        s.start();  
     }  
 });  
}

但我想要的是知道服务器启动，例外。我该如何做？

I.e。我如何从我的主线程知道后台服务器开始正常，所以我可以继续其余的操作？

But what I want is to know that the server started and did not throw an exception. How can I do that?
I.e. how can I know from my main thread that the background server started fine and so I can continue with the rest actions?

推荐答案

启动服务器。
等一下。
尝试在本地堆栈上连接到它。如果连接成功，您将获得胜利 - 只需关闭临时连接。

Start the server. Wait a bit. Try to connect to it on the local stack. If the connect succeeds, you have a winner - just close the temp connection.
