How to use twitter4j along with storm

Question

I use the twitter4j query interface to filter tweets http://twitter4j.org/javadoc/twitter4j/Query.html. But the twitter spout in https://github.com/nathanmarz/storm-starter/blob/master/src/jvm/storm/starter/spout/TwitterSampleSpout.java:43 uses queue.offer(status). I don't have a reference to Status, how do I integrate these API(s) to process live tweets.

Answer 1

This is what we have been using successfully to filter tweets:

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));
}
