RocketMQ消费数据一直为0

        private DefaultMQPushConsumer consumer;
    public Consumer(MessageListenerConcurrently listener, String consumerGroup) throws MQClientException{
        consumer = new DefaultMQPushConsumer(consumerGroup);
        consumer.setNamesrvAddr(RaceConfig.NameServerAddress);
        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);
        consumer.registerMessageListener(listener);
        consumer.subscribe(RaceConfig.MqTaobaoTradeTopic, "*");
        consumer.subscribe(RaceConfig.MqTmallTradeTopic, "*");
        consumer.subscribe(RaceConfig.MqPayTopic, "*");
    }
      
     这里是我正常的consumer设置,可是一直提示RocketMQ消费数据为0,求大神指教.  nameServerAddress要在这里设置吗?还是根本不用设置
