Springboot2.X整合RocketMQ(快速开始)

写在前面:

      本文将对rocktmq-spring-boot的设计实现做一个简单的介绍，读者可以通过本文了解将RocketMQ Client端集成为spring-boot-starter框架的开发细节，然后通过一个简单的示例来一步一步的讲解如何使用这个spring-boot-starter工具包来配置，发送和消费RocketMQ消息。下面直接上代码。

实现步骤：

1.项目结构：

2.pom.xml

        <!-- https://mvnrepository.com/artifact/org.apache.rocketmq/rocketmq-client -->
        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-client</artifactId>
            <version>4.6.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.rocketmq/rocketmq-common -->
        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-common</artifactId>
            <version>4.6.0</version>
        </dependency>

 

3.配置文件application.properties.

# 消费者的组名
apache.rocketmq.consumer.PushConsumer=orderConsumer
# 生产者的组名
apache.rocketmq.producer.producerGroup=Producer
# NameServer地址
apache.rocketmq.namesrvAddr=127.0.0.1:9876

4.Controller层

package com.core.controller;

import com.core.bean.JsonData;
import com.core.jms.MsgProducer;
import org.apache.rocketmq.client.exception.MQBrokerException;
import org.apache.rocketmq.client.exception.MQClientException;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;
import org.apache.rocketmq.remoting.common.RemotingHelper;
import org.apache.rocketmq.remoting.exception.RemotingException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
