redis.publish（）是什么方法在以下模块中执行

redis.publish（“WordCountTopology”，惊叹词dword.toString（）+“|”+Long.toString（count））


public void execute(Tuple tuple)
    {
      String word = tuple.getString(0);

      StringBuilder exclamatedWord = new StringBuilder();
      exclamatedWord.append(word).append("!!!");

      _collector.emit(tuple, new Values(exclamatedWord.toString()));

      long count = 30;
      redis.publish("WordCountTopology", exclamatedWord.toString() + "|" + Long.toString(count));
    }


它将字符串（EquiremateDWORD+“| 30”）发布到一个名为
WordCountTopology
的Redis频道-该频道的订户将在
Redis.publish执行后获得消息
