rocketMq springboot2 发送有序消息

有序消息：所有信息往mq中，在broker.conf配置文件中指定产生队列数量。

如果是普通队列时，所有消息，会分发到默认队列的各个队列中。是无序的。

有序则是，所有消息发送，都指定一个队列进行发送，而消费的消息也是一个接着一个消费。

主要应用场景：比如商品库存扣减，银行余额处理，订单处理结果等

消息生产者：

主要是使用发送的方法是这个syncSendOrderly，指定accountId 发送

import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Component;

import com.alibaba.fastjson.JSON;
import com.ccjr.api.utils.MqUtils;
import com.ccjr.base.BaseMqRequest;
import com.ccjr.commons.constants.RocketMqConstants;

import lombok.extern.slf4j.Slf4j;

/**
 * @desc：业务系统订单计算
 * @author 陈惟鲜
 * @date 2021年7月27日 下午2:01:02
 */
@Slf4j
@Component
public class OrderHandleSender {
    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    /**发送订单回报更新*/
    public void sendMessage(BaseMqRequest baseMqRequest) {
        // 发送前调用
        String jsonMsg = JSON.toJSONString(baseMqRequest);
        
        String destination = RocketMqConstants.TOPIC_A + ":" + RocketMqConstants.TAG_BIZ_ORDER_A;
        String accountId = baseMqRequest.getAccountId();
        SendResult sendResult = rocketMQTemplate.syncSendOrderly(destination, MessageBuilder.withPayload(jsonMsg).build(), accountId);
        log.info("sendMessage to topic {} sendResult={}", destination, sendResult);
    }
}

 

消息消费者：

指定消费模式：

consumeMode = ConsumeMode.ORDERLY

import java.util.Date;

import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;

        consumerGroup = RocketMqConstants.G_TAG_BIZ_ORDER_A,
        selectorExpression = RocketMqConstants.TAG_BIZ_ORDER_A,
        consumeMode = ConsumeMode.ORDERLY)
public class OrderHandleListener implements RocketMQListener<String> {
    
    @Override
    public void onMessage(String messageContext) {
        Date startTime = new Date();
        BaseMqRequest baseRequest = null;
        Exception ex = null;
        EntrustOrderResultDTO entrustOrderResultDTO = null; // 合并回报汇总
        try {
            String msg = "订单更新账单监听"+RocketMqConstants.TAG_BIZ_ORDER_HANDLE_RESULT+" 订单更新执行：\n"+messageContext;
            log.info(msg);
        }catch(Exception e) {
            log.error("接收处理异常", e);
            ex = e;

            // 入库mongodb
