SpringBoot 2.x | SpringBoot 整合 RocketMQ

1、maven 依赖

	
			org.springframework.boot
			spring-boot-starter-web
		
		
			org.apache.rocketmq
			rocketmq-spring-boot-starter
			2.0.3
		
		
			org.projectlombok
			lombok
		

2、application.yml 配置文件

rocketmq:
  name-server: 106.13.1.171:9876;
  producer:
    group: MyProducer
server:
  port: 8080

3、实体类

@Data
public class OrderEntity  implements Serializable {
    private String orderId;
    private String orderName;

    public OrderEntity(String orderId, String orderName) {
        this.orderId = orderId;
        this.orderName = orderName;
    }

    @Override
    public String toString() {
        return "OrderEntity{" +
                "orderId='" + orderId + '\'' +
                ", orderName='" + orderName + '\'' +
                '}';
    }
}

4、生产者

@RestController
public class ProducerController {
    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    @RequestMapping("/sendMsg")
    public String sendMsg() {
        OrderEntity orderEntity = new OrderEntity("123456", "Hly");
        rocketMQTemplate.convertAndSend("MyTopic", orderEntity);
        return "success";
    }

    public static void main(String[] args) {
        SpringApplication.run(ProducerController.class);
    }
}

5、消费者

@Service
@RocketMQMessageListener(topic = "MyTopic", consumerGroup = "MyConsumerGroup")
public class OrdeConsumer implements RocketMQListener {
    @Override
    public void onMessage(OrderEntity o) {
        System.out.println("o:" + o.toString());
    }
}

6、访问

http://localhost:8080/sendMsg
