如何使用twitter4j和storm

Question

我使用twitter4j查询接口过滤tweet http://twitter4j.org/javadoc/twitter4j/Query.html。但是https://github.com/nathanmarz/storm-starter/blob/master/src/jvm/storm/starter/spout/TwitterSampleSpout.java:43中的twitter喷口使用了queue.offer(status)。我没有参考状态，我如何集成这些API(s)来处理实时tweet。

这是我们成功使用的tweet过滤方法:

public void open(Map conf, TopologyContext context, SpoutOutputCollector collector) {
    queue = new LinkedBlockingQueue<Status>(1000);
    _collector = collector;
    StatusListener listener = new StatusListener() {
        public void onStatus(Status status) {
            queue.offer(status);
        }
        public void onDeletionNotice(StatusDeletionNotice sdn) {
        }
        public void onTrackLimitationNotice(int i) {
        }
        public void onScrubGeo(long l, long l1) {
        }
        public void onException(Exception e) {
        }
    };
    TwitterStreamFactory fact = new TwitterStreamFactory(new ConfigurationBuilder().setUser(_username).setPassword(_pwd).build());
    _twitterStream = fact.getInstance();
    _twitterStream.addListener(listener);
    _twitterStream.filter(new FilterQuery().track(TERMS_TO_TRACK).setIncludeEntities(true));
}
