import org.springframework.stereotype.Component;

/**

@Component
public class RocketMQProducer {

    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    @Value("${rocketmq.producer.topic.xzh}")
    private String topic;

    @Value("${rocketmq.producer.tag.xzh}")
    private String tag;

    public void send(String msg) {
        if (StringUtils.isBlank(msg)) {
            return;
        }
        rocketMQTemplate.syncSend(topic + ":" + tag, msg);
    }

@Slf4j
@Component
@RocketMQMessageListener(consumerGroup = "${rocketmq.consumer.group}", topic = "${rocketmq.consumer.topic.xzh}", selectorExpression = "${rocketmq.consumer.tag.xzh}")
public class RocketMQConsumerListener implements RocketMQListener<String> {
