3.生产者（异步发送示例）

//异步发送消息代码示例
rocketMqUtil.sendAsyncMsg(RocketConstant.TEST_TOPIC1, RocketConstant.TEST_TAG1, UUID.randomUUID().toString(), "测试消息一");

4.消费者

简单的负载均衡消费的示例（指定topic和tag，相同的组即为负载均衡消费）

也可以指定不同的topic和不同的tag进行消息区分

注意线上和本地连接同一个MQ也会导致负载均衡，导致线上消息丢失

    @RocketMQMessageListener(consumerGroup = "1",
            topic = RocketConstant.TEST_TOPIC1,
            selectorExpression = RocketConstant.TEST_TAG1)
    @Service
    public class RocketConsumerTag1 implements RocketMQListener<String> {
        @Override
        public void onMessage(String message) {
            String orderNo = message;
            log.info("tag1，接收：{}", orderNo);

        }
    }

    @RocketMQMessageListener(consumerGroup ="1",
            topic = RocketConstant.TEST_TOPIC1,
            selectorExpression = RocketConstant.TEST_TAG1)
    @Service
    public class RocketConsumerTag2 implements RocketMQListener<String> {
        @Override
        public void onMessage(String message) {
            String orderNo = message;
            log.info("tag2，接收：{}", orderNo);

        }
    }
