RocketMQ实战记录

背景

客户需要用企业微信通知客户。

先上代码
下面是异步生产者的代码，第一次发送时会报错，如下所示

2023-12-22 16:46:57.577  INFO 20832 --- [enderExecutor_1] c.c.m.plan.service.WeixinBasicsProducer  : 异步发送 - 发送失败

    /**

    public void async(List<OperationRoleDTO> listMap) {
        WeixinLog weixinLog = new WeixinLog();
        weixinLog.setType("sentRktMq");
        weixinLog.setParameter(JsonUtils.toJsonArray(listMap).toString());
        weixinLogService.save(weixinLog);
        String text = "基本信息案例-异步发送" + System.currentTimeMillis();
        log.info(text);

        for (int a = 0; a < listMap.size(); a++) {
            OperationRoleDTO operationRoleDTO = listMap.get(a);
            rocketMQTemplate.asyncSend("asyncSend", listMap.get(a), new SendCallback() {

                // SendCallback接收异步返回结果的回调
                // 成功发送
                @Override
                public void onSuccess(SendResult sendResult) {

                    log.info("异步发送 - 发送成功");
                }

                // 发送失败

                    //异步发送者失败后，会再次发送一次
                    weixinBasicsProducerFail.sent(operationRoleDTO);
                }
            });
        }
        log.info("异步发送-已发送...");
    }
}

异步发送者失败后，会再次发送一次,调用一下代码

package com.chinaztt.mes.plan.service;

import com.chinaztt.mes.technology.dto.OperationRoleDTO;
import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.client.producer.SendCallback;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;


/**
 *
 * 当发送失败消息时，再次发送---异步消息
 *
 */
@Service
@Slf4j
public class WeixinBasicsProducerFail {
    @Resource
    RocketMQTemplate rocketMQTemplate;

    public void sent(OperationRoleDTO operationRoleDTO){

        rocketMQTemplate.asyncSend("asyncSendFail", operationRoleDTO, new SendCallback() {

            // SendCallback接收异步返回结果的回调
            // 成功发送
            @Override
            public void onSuccess(SendResult sendResult) {
                log.info("异步发送 - 发送成功");
            }

            // 发送失败
            @Override
            public void onException(Throwable throwable) {
                log.info("异步发送 - 发送失败");
                throwable.printStackTrace();

            }
        });
    }

}

下面开始消费者代码

package com.chinaztt.mes.plan.service;


import com.chinaztt.mes.common.util.JsonUtils;
import com.chinaztt.mes.plan.entity.WeixinLog;
import com.chinaztt.mes.technology.dto.OperationRoleDTO;
import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;
import java.util.concurrent.TimeUnit;

/**
 * 异步消息
 */
@Component
@RocketMQMessageListener(selectorExpression = "", topic = "asyncSend", consumerGroup = "asyncSend")
@Slf4j
public class WeixinAsyncConsumer implements RocketMQListener<OperationRoleDTO> {
    @Resource
    WeixinLogService weixinLogService;
    @Resource
    WeixinBasicsProducerFail weixinBasicsProducerFail;

    @Override
    public void onMessage(OperationRoleDTO map) {
        Integer integer = 0;
        //上线后解开
        //integer = SendWxCpMsgUtil.sendToWxCp(map.getUsername(), map.getMessage());
        if (integer != 1) {
            try {
                TimeUnit.SECONDS.sleep(5);

            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
            weixinBasicsProducerFail.sent(map);
        }
        WeixinLog weixinLog = new WeixinLog();
        weixinLog.setType("sentWeixin");
        weixinLog.setParameter(JsonUtils.toJsonObject(map).toString());
        weixinLog.setResult(String.valueOf(integer));
        weixinLogService.save(weixinLog);

        log.info("异步消息-接受到消息: {}{}", map.getUsername(), map.getMessage());
    }

}

下面是异步消费者的代码

package com.chinaztt.mes.plan.service;


import com.chinaztt.mes.common.util.JsonUtils;
import com.chinaztt.mes.plan.entity.WeixinLog;
import com.chinaztt.mes.technology.dto.OperationRoleDTO;
import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * 异步消息
 */
@Component
@RocketMQMessageListener(selectorExpression = "", topic = "asyncSendFail", consumerGroup = "asyncSendFail")
@Slf4j
public class WeixinAsyncConsumerFail implements RocketMQListener<OperationRoleDTO> {
    @Resource
    WeixinLogService weixinLogService;
    @Override
    public void onMessage(OperationRoleDTO map) {
        Integer integer = 0;
        //上线后解开
        //integer = SendWxCpMsgUtil.sendToWxCp(map.getUsername(), map.getMessage());

        WeixinLog weixinLog = new WeixinLog();
        weixinLog.setType("sentWeixin");
        weixinLog.setParameter(JsonUtils.toJsonObject(map).toString());
        weixinLog.setResult(String.valueOf(integer));
        weixinLogService.save(weixinLog);

        log.info("异步消息-接受到消息: {}{}", map.getUsername(), map.getMessage());
    }

}

下面是生产者的重试机制

package com.chinaztt.mes.plan.service;

import org.apache.rocketmq.client.exception.MQClientException;
import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;

/**
 * Producer，发送消息
 */
public class Producer {
    public static void main(String[] args) throws MQClientException, InterruptedException {
        DefaultMQProducer producer = new DefaultMQProducer("group_name");
        producer.setNamesrvAddr("192.168.2.222:9876;192.168.2.223:9876");
        producer.setRetryTimesWhenSendFailed(3);
        producer.start();

        for (int i = 0; i < 100; i++) {
            try {
                Message msg = new Message("TopicTest", 				// topic
                        "TagA", 									// tag
                        ("HelloWorld - RocketMQ" + i).getBytes()	// body
                );
                SendResult sendResult = producer.send(msg, 1000);
                System.out.println(sendResult);
            } catch (Exception e) {
                e.printStackTrace();
                Thread.sleep(1000);
            }
        }

        producer.shutdown();
    }
}

下面是消费者的重试代码

package com.chinaztt.mes.plan.service;

    import javax.annotation.PostConstruct;
    import java.util.List;

/**

@Slf4j
@Service
public class MessageConsumer implements MessageListenerConcurrently {

    private String namesrvAddr;*/

    private final DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("DefaultConsumer");


    @PostConstruct
    public void start() {
        try {
            consumer.setNamesrvAddr("10.1.200.45:9876");

            //从消息队列头部开始消费
            consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

            //设置集群消费模式
            consumer.setMessageModel(MessageModel.CLUSTERING);

            //订阅主题
            consumer.subscribe("asyncSendwew", "*");

            //注册消息监听器
            consumer.registerMessageListener(this);

            //启动消费端
            consumer.start();

            log.info("Message Consumer Start...");
            System.err.println("Message Consumer Start...");
        } catch (MQClientException e) {
            log.error("Message Consumer Start Error!!",e);
        }

    }

    @Override
    public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs, ConsumeConcurrentlyContext context) {
        if (CollectionUtils.isEmpty(msgs)) {
            return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
        }

        MessageExt message = msgs.get(0);
        try {
            //逐条消费
            String messageBody = new String(message.getBody(), RemotingHelper.DEFAULT_CHARSET);
            System.err.println("Message Consumer: Handle New Message: messageId: " + message.getMsgId() + ",topic: " +

            log.error("Consume Message Error!!", e);
            //抛出异常时，返回ConsumeConcurrentlyStatus.RECONSUME_LATER，尝试重试。当重试指定次数后返回ConsumeConcurrentlyStatus.CONSUME_SUCCESS
            int reconsumeTimes = message.getReconsumeTimes();
