实战背景：用一篇文章能实战说明，SpringBoot+RabbitMQ的集成，因为涉及到安装和代码编写的知识点，从如下七步法，构建工程，具体关系如下：

工程需求：发送和接收消息

业务分析：安装MQ,然后集成SpringBoot

准备工作：

第一步：需要下载安装erlong环境。地址是：http://www.erlang.org/downloads

里面有windows和linux，测试环境是windows所以下载的是OTP 20.2 Windows 64-bit Binary File

第二步：下载安装rabbitMQ

同理下载windows版本的。下载地址：http://www.rabbitmq.com/download.html，选择window installer

安装完成后，进入C:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.6\sbin目录，执行如下命令

rabbitmq-service.bat stop  

rabbitmq-service.bat install  

rabbitmq-service.bat start 

第三步：rabbitmq自带管理后台，安装后需要配置开启

进入rabbitmq安装目录中的sbin目录执行

rabbitmq-plugins enable rabbitmq_management

重启rabbitmq服务生效

打开http://localhost:15672/即可看到管理后台

用户名密码均为guest

实战开始了！！！

第一步；构建工程

第二步：构建pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.4.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.example</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><name>Rabbitmq_QueueDemo</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

第三步：构建application.properties文件

spring.application.name=rabbitmq-hellospring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

第四步：配置队列

package com.example.demo.config;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** @author changyaobin* @data 2/25/2019 7:31 PM*/
@Configuration
public class RabbitmqConfig {@Beanpublic Queue queue() {return new Queue("Queue1");}
}

第五步：创建接收者

package com.example.demo.mq;import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;/*** @author 常耀斌* @data 2019/02/03 11:07*/
@Component
@RabbitListener(queues = "Queue1")//监听QueueHello的消息队列
public class ReceiverA {@RabbitHandler//@RabbitHandler来实现具体消费public void QueueReceiver(String Queue1) {System.out.println("Receiver A: " + Queue1);}}

第六步：创建发送者

package com.example.demo.mq;import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;import java.util.Date;/*** @author changyaobin* @data 2019/02/03 11:06* rabbitTemplate是springboot 提供的默认实现*/
@Component
public class SenderA {@Autowiredprivate AmqpTemplate rabbitTemplate;public void send(String context) {System.out.println("Sender : " + context);//使用AmqpTemplate将消息发送到消息队列QueueHello中去this.rabbitTemplate.convertAndSend("Queue1", context);}}

第七步：单元测试

package com.example.demo.controller;import com.example.demo.mq.SenderA;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageBuilder;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.retry.backoff.Sleeper;
import org.springframework.test.context.junit4.SpringRunner;import java.util.Date;/*** Copyright (C), 2019-2019, XXX有限公司* FileName: QueueSendTest* Author:   常耀斌* Date:     2019/4/22 22:22** @Description: $description$* History:* <author>          <time>          <version>          <desc>* 作者姓名           修改时间           版本号              描述*/
@SpringBootTest
@RunWith(SpringRunner.class)public class MQTest {/*** @Description: 测试发送和接收队列*/@Autowiredprivate SenderA queueSender;@Autowiredprivate AmqpTemplate amqpTemplate;@Testpublic void QueueSend() {int i = 2;for (int j = 0; j < i; j++) {String msg = "Queue1 msg" + j + new Date();try {queueSender.send(msg);} catch (Exception e) {e.printStackTrace();}}}@Testpublic void send() {Message message = MessageBuilder.withBody("body content".getBytes()).setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN).setMessageId("1").setHeader("header", "header").build();amqpTemplate.send("Queue1", message);amqpTemplate.convertAndSend("Queue1", "body content");}}

第四步：结果展示
