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

</project>
第三步：构建application.properties文件
spring.application.name=rabbitmq-hello
spring.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 {
@Bean
public 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 {
@Autowired
private 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;

*/
@SpringBootTest
@RunWith(SpringRunner.class)
public class MQTest {
/**
* @Description: 测试发送和接收队列
*/
@Autowired
private SenderA queueSender;
@Autowired
private AmqpTemplate amqpTemplate;
@Test
public 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();
}
}
}
@Test
public 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");
}
