本文介绍如何在Spring Boot项目中集成RabbitMQ，包括添加依赖、配置应用、定义交换机与队列，以及使用RabbitTemplate进行消息发送。通过示例代码展示了主题交换机的使用，并演示了如何在消费者端接收消息。

添加依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </dependency>

添加配置文件
application.yml

server:
  port: 44000
spring:
  application:
    name: test-rabbitmq-producer
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    virtualHost: /

RabbitmqCofig.java

package com.xuecheng.test.rabbitmq.config;

import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**

 */
@Configuration
public class RabbitmqConfig {
    public static final String QUEUE_INFORM_EMAIL = "queue_inform_email";
    public static final String QUEUE_INFORM_SMS = "queue_inform_sms";
    public static final String EXCHANGE_TOPICS_INFORM="exchange_topics_inform";
    public static final String ROUTINGKEY_EMAIL="inform.#.email.#";
    public static final String ROUTINGKEY_SMS="inform.#.sms.#";

    //声明交换机
    @Bean(EXCHANGE_TOPICS_INFORM)
    public Exchange EXCHANGE_TOPICS_INFORM(){
        //durable(true) 持久化，mq重启之后交换机还在
        return ExchangeBuilder.topicExchange(EXCHANGE_TOPICS_INFORM).durable(true).build();
    }

    //声明QUEUE_INFORM_EMAIL队列
    @Bean(QUEUE_INFORM_EMAIL)
    public Queue QUEUE_INFORM_EMAIL(){
        return new Queue(QUEUE_INFORM_EMAIL);
    }
    //声明QUEUE_INFORM_SMS队列
    @Bean(QUEUE_INFORM_SMS)
    public Queue QUEUE_INFORM_SMS(){
        return new Queue(QUEUE_INFORM_SMS);
    }

    //ROUTINGKEY_EMAIL队列绑定交换机，指定routingKey
    @Bean
    public Binding BINDING_QUEUE_INFORM_EMAIL(@Qualifier(QUEUE_INFORM_EMAIL) Queue queue,
                                              @Qualifier(EXCHANGE_TOPICS_INFORM) Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with(ROUTINGKEY_EMAIL).noargs();
    }
    //ROUTINGKEY_SMS队列绑定交换机，指定routingKey
    @Bean
    public Binding BINDING_ROUTINGKEY_SMS(@Qualifier(QUEUE_INFORM_SMS) Queue queue,
                                          @Qualifier(EXCHANGE_TOPICS_INFORM) Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with(ROUTINGKEY_SMS).noargs();
    }


}

测试代码

package com.xuecheng.test.rabbitmq;

import com.xuecheng.test.rabbitmq.config.RabbitmqConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * @author Renes
 * @create 2018-11-25 22:37
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class Producer05_topic_springboot {

    @Autowired
    RabbitTemplate rabbitTemplate;

    //使用rabbitTemplate发送消息
    @Test
    public void testRabbitTemplate(){

        String message = "send email message to user";
        /**
         * 参数配置
         * 1、交换机名称
         * 2、rountingKey
         *
         */
        rabbitTemplate.convertAndSend(RabbitmqConfig.EXCHANGE_TOPICS_INFORM,"inform.email",message);
    }


}

测试结果
在这里插入图片描述

消费者代码：
添加注解@RabbitListener

package com.xuecheng.test.rabbitmq.mq;

import com.xuecheng.test.rabbitmq.config.RabbitmqConfig;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

import java.nio.channels.Channel;

/**
 * @author Renes
 * @create 2018-11-26 0:00
 */
@Component
public class ReceiveHandler {

    @RabbitListener(queues = {RabbitmqConfig.QUEUE_INFORM_EMAIL})
    public void send_email(String msg, Message message, Channel channel){
        System.out.println("receive message is "+msg);
    }
}
