方式1：

@Component
@RocketMQMessageListener(topic = "",consumerGroup="group1")
public class MessageListener1 implements RocketMQListener<String>, RocketMQPushConsumerLifecycleListener {
    @Override
    public void onMessage(String str) {
    }
 
    @Override
    public void prepareStart(DefaultMQPushConsumer consumer) {
        try{
            consumer.subscribe("topic-a","*");
            consumer.subscribe("topic-b","*");
            consumer.registerMessageListener((List<MessageExt> messages, ConsumeConcurrentlyContext context) -> {
                    if (CollectionUtils.isNotEmpty(messages)) {
                        for (MessageExt message : messages) {
                            System.out.println(Thread.currentThread().getName()+"消费完成:"+message.getTopic()+ new String(message.getBody()));
                        }
                    }
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
                });
            }catch (MQClientException e){
            e.printStackTrace();
        }
    }
}
