java - 如何在 Java 中多线程打开网络连接？

Question

我正在开发一个多线程 Java 项目，我的一个线程正在联系一个网页。目前我这样做如下：

URLConnection urlConn = webPageToContact.openConnection();
InputStreamReader inStream = new InputStreamReader(urlConn.getInputStream());
BufferedReader buff  = new BufferedReader(inStream);

我的问题是，有没有办法以线程方式执行此操作，以便在该线程等待服务器响应时，我项目中的其他线程可以做事。我正在考虑某种“等待”方法。谢谢！

Answer 1

您还可以使用单线程池执行器：

ExecutorService service = Executors.newSingleThreadExecutor();
   service.submit(new Runnable() {
   @Override public void run() {
      URLConnection urlConn = webPageToContact.openConnection();
      InputStreamReader inStream = new InputStreamReader(urlConn.getInputStream());
      BufferedReader buff  = new BufferedReader(inStream);
      // put data in queue or some other data structure
   }    
});

service.shutdown();

尝试这个：

Thread webReader = new Thread(){
    public void run(){
        URLConnection urlConn = webPageToContact.openConnection();
        InputStreamReader inStream = new InputStreamReader(urlConn.getInputStream());
        BufferedReader buff  = new BufferedReader(inStream);
    }
});
webReader.setDaemon(true);
webReader.start();
