最新RocketMq与SpringBoot整合

最新版的RocketMq与SpringBoot2.X进行整合可以利用rocketmq-spring-boot-starter来简化配置，本文采用了最新版的jar包来整合，并且略微做了封装，以便于其他模块引用，适合于多生产者多消费者的情况。

项目依赖

主要用到了rocketmq的包和lombok的包，具体的依赖如下所示：

        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-spring-boot-starter</artifactId>
            <version>2.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.12</version>
        </dependency>

配置项

rocketmq.name-server=127.0.0.1:9876
rocketmq.producer.enable=true

rocketmq.producer.group=test-group-e
rocketmq.producer.topic=test-topic-e

rocketmq.producer.group2=test-group-f
rocketmq.producer.topic2=test-topic-f



rocketmq.consume.group=consumer-group-3
rocketmq.consume.topic=test-topic-e

rocketmq.consume.group2=consumer-group-4
rocketmq.consume.topic2=test-topic-f

最重要的是rocketmq.name-server和rocketmq.producer.group这两个属性一定要配置，否则项目无法启动，在封装成中间件的时候rocketmq.producer.group可以随意指定一个，亲测即便指定了也不会在启动的时候就生成这个生产者的group.rocketmq.producer.enable这个是我自己加的，为了让rocketmq能按需加载，因为封装成中间件的话其他模块引入，有的可能用不到，所以bean需要按条件加载。 剩下的group和topic我分别都指定了两个，为了模拟多消费者和多生产者的情况。没有用tag来区分，因为Tag使用不当会引来不必要的麻烦，不同的功能严格按照topic和group来区分。

封装的消息类

package com.rocket.mq.demo.controller;

import lombok.Data;

import java.io.Serializable;

/**
 * @author : zhangwei
 * @description : 消息
 * @date: 2020-08-20 11:03
 */

@Data
public class RocketMqMessage<T> implements Serializable {
    /**
     * 消息内容
     */
    private T content;


    /**
     * 消息的key
     */
    private String msgKey;

    /**
     * topic
     */
    private String producerTopic;
    /**
     * group
     */
    private String producerGroup;
    /**
     * tag
     */
    private String producerTag;
}

发送消息的公共方法

package com.rocket.mq.demo.controller;

import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.apache.rocketmq.client.producer.SendResult;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Component;

import java.util.UUID;

/**

@Component
@Slf4j

public class MqSendService {

    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    /**

     **/
    private <T> SendResult send(T msg, String topic, String group, String tag) {
        if (StringUtils.isBlank(topic) || StringUtils.isBlank(group)) {
            new Throwable("发送方topic或者group不能为空");
        }
        String uuid = UUID.randomUUID().toString().replaceAll("-", "");
        RocketMqMessage message = new RocketMqMessage();
        message.setProducerTopic(topic);
        message.setProducerGroup(group);
        message.setProducerTag(tag);
        message.setContent(msg);
        message.setMsgKey(uuid);
        // 发送消息
        Message messageFinal = MessageBuilder.withPayload(message).setHeader("KEYS", uuid).build();
        String destination = topic;
        if (StringUtils.isNotBlank(tag)) {
            destination = topic + ":" + tag;
        }
        SendResult result = rocketMQTemplate.syncSend(destination, messageFinal);
        log.info("成功发送消息,消息内容为:{},返回值为:{}", message, result);
        return result;
    }

    /**
     * 发送不带tag的消息

     * @param msg
     * @param topic
     * @param group
     * @author: zhangwei
     * @date: 2020/8/21 10:54
     * @return: org.apache.rocketmq.client.producer.SendResult
     **/
    public <T> SendResult send(T msg, String topic, String group) {
        return this.send(msg, topic, group, null);
    }


}
