Question

我已经为twitter实现了一个Steaming API。我完美地得到了溪流。但是，我的计划永远不会结束。我尝试了很多组合，但无法弄清楚原因。我在java中起诉Apache AsyncHttpClient。我的目标是启动流例如10秒，获取流，并优雅地关闭流并退出应用程序（我希望当我的Main方法自然结束时会发生这种情况）。这是下面的代码：



public static void main(String[] args) throws Exception
{
    TwitterStreamingHttpClient client = new TwitterStreamingHttpClient();
    Executor ex = Executors.newSingleThreadExecutor();
    ex.execute(client);

    Thread.sleep(5000);
    client.ceaseStream();

    LOG.debug("Keeps running");     
}

而这：

public static void main(String[] args) throws Exception
{
    TwitterStreamingHttpClient client = new TwitterStreamingHttpClient();
    Executor ex = Executors.newSingleThreadExecutor();
    ex.execute(client);

    Thread.sleep(5000);
    client.ceaseStream();

    LOG.debug("Keeps running");     
}

我尝试添加一个返回，尽管它可能会有所帮助。但没有运气。有人可以帮我这个吗？

编辑1：当我使用调试模式时，我可以看到“initiateSTream Thread”线程。主线程消失时仍在运行！

编辑2（解决方案）：在main方法中，我替换了：


public class TwitterStreamingHttpClient extends DefaultHttpAsyncClient implements Runnable
{
    private final static Logger LOG = LoggerFactory.getLogger(TwitterStreamingHttpClient.class);
    /**
     * @throws IOReactorException
     */
    public TwitterStreamingHttpClient() throws IOReactorException
    {
        super();
        // TODO: parametrize it, load from config file, spring config file?
        this.getCredentialsProvider().setCredentials(new AuthScope("stream.twitter.com", 80),
                new UsernamePasswordCredentials("username", "password"));
        this.start();
    }
    public void initiateStream() throws UnsupportedEncodingException, InterruptedException, ExecutionException
    {

        String requestContent = new String();

        requestContent = "track=NothingFeelsBetterThan";
        Future future = this.execute(HttpAsyncMethods.createPost(
                "https://stream.twitter.com/1.1/statuses/filter.json", requestContent,
                ContentType.APPLICATION_FORM_URLENCODED), new TwitConsumer(), null);
        Boolean result = future.get();
        if(result==null)
        {
            LOG.error("Requested to close stream!");
            return;
        }
    }
    public void ceaseStream()
    {
        try
        {
            this.shutdown();
            LOG.info("Shutting down the stream");
        }
        catch (InterruptedException e)
        {
            LOG.debug("InterruptedException {}", e);
        }
    }

/*
 * (non-Javadoc)
 * 
 * @see java.lang.Runnable#run()
 */
public void run()
{
    Thread.currentThread().setName("initiateSTream Thread");
    try
    {
        initiateStream();
        Thread.currentThread().interrupt();
    }
    catch (UnsupportedEncodingException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    catch (InterruptedException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    catch (ExecutionException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

使用：

/*
 * (non-Javadoc)
 * 
 * @see java.lang.Runnable#run()
 */
public void run()
{
    Thread.currentThread().setName("initiateSTream Thread");
    try
    {
        initiateStream();
        Thread.currentThread().interrupt();
    }
    catch (UnsupportedEncodingException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    catch (InterruptedException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    catch (ExecutionException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

现在我的节目在指定的流媒体时间后结束。但为什么？这两种方法有什么区别？！
