先启动命名服务器

启动后可以测试是否启动成功

SpringBoot整合RocketMQ

导坐标

        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-spring-boot-starter</artifactId>
            <version>2.2.3</version>
        </dependency>

改配置

rocketmq:
  name-server: localhost:9876
  producer:
    group: group_rocketmq

实现消息生产与消费

普通的生产消息

异步的生产消息

@Service
public class MessageServiceRocketmqImpl implements MessageService {

    @Autowired
    private RocketMQTemplate rocketMQTemplate;
    @Override
    public void sendMessage(String id) {
        System.out.println("待发送短信的订单已纳入处理队列 （roeket topic）,id:" + id);
//        rocketMQTemplate.convertAndSend("order_id",id);  // 同步消息
        SendCallback callback = new SendCallback() {
            @Override
            public void onSuccess(SendResult sendResult) {
                System.out.println("消息发送成功");
            }

            @Override
            public void onException(Throwable throwable) {
                System.out.println("消息发送失败");
            }
        };
        rocketMQTemplate.asyncSend("order_id",id,callback);  //  异步消息
    }


    @Override
    public String doMessage() {
        return null;
    }
}

消费消息就是用监听

@Component
@RocketMQMessageListener(topic = "order_id",consumerGroup = "group_rocketmq")
public class MessageListener implements RocketMQListener<String> {
    @Override
    public void onMessage(String id) {
        System.out.println("已完成短信发送业务(rocketmq)：id:" + id);

    }
}
