spring-cloud-alibaba整合rocketMQ

---

生产者与消费者 加依赖

根据自己的MQ版本来指定版本号

<dependency>
  <groupId>org.apache.rocketmq</groupId>
   <artifactId>rocketmq-spring-boot-starter</artifactId>
   <version>2.0.3</version>
</dependency>

生产者

2.加配置

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

---

3.编写生产者

private final RocketMQTemplate rocketMQTemplate;


//convertAndSend(topic,发送的数据);
rocketMQTemplate.convertAndSend("add_bouns", UserAddBonusMsgDTO.builder().userId(share.getUserId()).bonus(50).build());
     

消费者

4.加配置

rocketmq:
  name-server: localhost:9876

5.编写消费者

import com.itmuch.usercenter.dao.user.BonusEventLogMapper;
import com.itmuch.usercenter.dao.user.UserMapper;
import com.itmuch.usercenter.domain.entity.dto.massaging.UserAddBonusMsgDTO;
import com.itmuch.usercenter.domain.entity.user.BonusEventLog;
import com.itmuch.usercenter.domain.entity.user.User;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Date;

@Slf4j
@RocketMQMessageListener(consumerGroup = "consumer-group",topic = "add_bouns")
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
@Service
public class AddBonusListener implements RocketMQListener<UserAddBonusMsgDTO> {

    private final UserMapper userMapper;
    private final BonusEventLogMapper  bonusEventLogMapper;
    @Override
    public void onMessage(UserAddBonusMsgDTO userAddBonusMsgDTO) {
		//业务逻辑
        User user = userMapper.selectByPrimaryKey(userAddBonusMsgDTO.getUserId());
        user.setBonus(user.getBonus()+userAddBonusMsgDTO.getBonus());
        userMapper.updateByPrimaryKey(user);
        bonusEventLogMapper.insert(BonusEventLog.builder().userId(user.getId()).event("UPDATE").createTime(new Date()).description("加积分").value(userAddBonusMsgDTO.getBonus()).build());

    }
}

注意

生产者的group写在配置文件
消费者的group写在注解里
