修改application.properties

## application.properties
rocketmq.name-server=127.0.0.1:9876

注意:

请将上述示例配置中的127.0.0.1:9876替换成真实RocketMQ的NameServer地址与端口

编写代码

@SpringBootApplication
public class ConsumerApplication{
    
    public static void main(String[] args){
        SpringApplication.run(ConsumerApplication.class, args);
    }
    
    @Slf4j
    @Service
    @RocketMQMessageListener(topic = "test-topic-1", consumerGroup = "my-consumer_test-topic-1")
    public class MyConsumer1 implements RocketMQListener<String>{
        public void onMessage(String message) {
            log.info("received message: {}", message);
        }
    }
    
    @Slf4j
    @Service
    @RocketMQMessageListener(topic = "test-topic-2", consumerGroup = "my-consumer_test-topic-2")
    public class MyConsumer2 implements RocketMQListener<OrderPaidEvent>{
        public void onMessage(OrderPaidEvent orderPaidEvent) {
            log.info("received orderPaidEvent: {}", orderPaidEvent);
        }
    }
}
