2）配置文件

# application.properties
rocketmq.name-server=192.168.25.135:9876;192.168.25.138:9876
rocketmq.producer.group=my-group

3）启动类

@SpringBootApplication
public class MQProducerApplication {
    public static void main(String[] args) {
        SpringApplication.run(MQSpringBootApplication.class);
    }
}

4）测试类

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {MQSpringBootApplication.class})
public class ProducerTest {
​
    @Autowired
    private RocketMQTemplate rocketMQTemplate;
​
    @Test
    public void test1(){
        rocketMQTemplate.convertAndSend("springboot-mq","hello springboot rocketmq");
    }
}

消息消费者

1）添加依赖

同消息生产者

2）配置文件

3）启动类

@SpringBootApplication
public class MQConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(MQSpringBootApplication.class);

}

4）消息监听器

@Slf4j
@Component
@RocketMQMessageListener(topic = "springboot-mq",consumerGroup = "springboot-mq-consumer-1")
public class Consumer implements RocketMQListener<String> {
