#test我需要使用 twitter4j在所有带有特定主题标签（比如说）的新推文上更新我的 java 应用程序。由于避免对 twitter REST API 进行连续轮询，我将使用 Twitter Stream API。

运行此代码，我期望：

  1. 运行代码
  2. 打开浏览器，转到 Twitter 并发布包含以下内容的推文#test
  3. 仅在我的应用程序上查看带有特定哈希码的推文的打印

但是..我在我的应用程序中看不到任何东西..（见编辑）

有人可以给我一些建议吗？

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
  .setOAuthConsumerKey(CONSUMER_KEY)
  .setOAuthConsumerSecret(CONSUMER_SECRET)
  .setOAuthAccessToken(ACCESS_TOKEN)
  .setOAuthAccessTokenSecret(ACCESS_TOKEN_SECRET);

TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();

StatusListener listener = new StatusListener() {
    @Override
    public void onStatus(Status status) {
        System.out.println("@" + status.getUser().getScreenName() + " - " + status.getUser().getId() + " - " + status.getText());
    }
    @Override
    public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {
        System.out.println("Post Deletado:" + statusDeletionNotice.getStatusId());
    }
    @Override
    public void onTrackLimitationNotice(int numberOfLimitedStatuses) {
        System.err.println("Limitação:" + numberOfLimitedStatuses);
    }
    @Override
    public void onScrubGeo(long userId, long upToStatusId) {
        System.out.println("Got scrub_geo event userId:" + userId + " upToStatusId:" + upToStatusId);
    }
    @Override
    public void onStallWarning(StallWarning warning) {
        System.out.println("Got stall warning:" + warning);
    }
    @Override
    public void onException(Exception ex) {
        ex.printStackTrace();
    }
};

List<String> queries = new ArrayList<String>();
queries.add("#test");

twitterStream.addListener(listener);
twitterStream.firehose(20);

String[] trackQueries = (String[]) queries.toArray(new String[queries.size()]);

FilterQuery filterQuery = new FilterQuery();
twitterStream.filter(filterQuery.track(trackQueries));

编辑：

在修复了一些错误后，我正在阅读 sys.out 中的一些内容，但是.. 在一些错误之后似乎是随机的东西：

然后是一些像这样的随机推文：

只有通过经销商选择的公司才能访问 twitter firehose。因此，除非您是这些公司之一，否则您希望使用sample()而不是firehose. 不过，您应该会看到一些日志。您确定您的记录器设置正确吗？

编辑： 阅读文档的这一部分并添加一个有效的 twitter4j.properties 文件。请注意，您必须在 twitter 上注册才能获得访问令牌。一旦你有了一个令牌并填写了配置文件，你就可以将它包含在你的类路径中。
