application.yml文件

spring:
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    publisher-confirms: true
    virtual-host: /

  application:
    name: rabbitMQ

 RabbitMQConfiguration.java

package com.example.demo;

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitMQConfiguration {

    private static final String QUEUE_SIMPLE_NAME = "hello";

    // 队列
    @Bean
    public Queue queue(){
        return new Queue(QUEUE_SIMPLE_NAME);
    }

}

创建消息的消费者 Consumer,java

package com.example.demo;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * @author: DevanYan
 * @create: 2019-05-28 11:46
 */

//消息的消费者
@Component
@RabbitListener(queues = "hello")
public class Consumer {

    @RabbitHandler
    public void use(String message) {
        System.out.println("消费了一条消息 : " + message);
    }

}

创建消息的生产者 Creater.java

package com.example.demo;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * @author: DevanYan
 * @create: 2019-05-28 11:47
 */

// 消息的生产者
@Component
public class Creater {

    @Autowired
    private AmqpTemplate amqpTemplate;

    public void  create(){
        String message = "Hello RabbitMQ !";
        amqpTemplate.convertAndSend("hello", message);
        System.out.println("创建了一条消息 : " + message);
    }

}

编写测试类

package com.example.demo;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {
    @Autowired
    Creater creater;

    @Test
    public void creatertest(){
        creater.create();
    }

}
