2.配置文件（application.yml）

3.配置类，配置Exchange、Queue、及绑定交换机。

package com.rabbitmq.demo.conf;

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

/**
 * @Author JiangBeiPing
 * @Date 2020/1/13 12:02
 * @Version 1.0
 **/
@Configuration
public class RabbitmqConfig {

    public static final String QUEUE_INFORM_EMAIL = "queue_inform_A";//创建的队列的名称
    public static final String QUEUE_INFORM_SMS = "queue_inform_B";//创建的队列的名称
    public static final String EXCHANGE_TOPICS_INFORM="exchange_topics";//创建的交换机的名称

    /**
     *  交换机配置
     *   ExchangeBuilder提供了fanout、direct、topic、header交换机类型的配置
     * @return 交换机
     */
    @Bean(EXCHANGE_TOPICS_INFORM)
    public Exchange EXCHANGE_TOPICS_INFORM(){
        //durable(true)持久化，消息队列重启后交换机仍然存在
        return ExchangeBuilder.topicExchange(EXCHANGE_TOPICS_INFORM).durable(true).build();
    }

    //声明队列
    @Bean(QUEUE_INFORM_SMS)
    public Queue QUEUE_INFORM_SMS() {
        Queue queue = new Queue(QUEUE_INFORM_SMS);
        return queue;
    }

    //声明队列
    @Bean(QUEUE_INFORM_EMAIL)
    public Queue QUEUE_INFORM_EMAIL() {
        Queue queue = new Queue(QUEUE_INFORM_EMAIL);
        return queue;
    }

    /**
     *  channel.queueBind(INFORM_QUEUE_SMS,"inform_exchange_topic","inform.#.sms.#")
     * 绑定队列到交换机
     * @param queue 队列
     * @param exchange 交换机
     * @return
     */
    @Bean
    public Binding BINDING_QUEUE_INFORM_SMS(@Qualifier(QUEUE_INFORM_SMS) Queue queue, @Qualifier(EXCHANGE_TOPICS_INFORM) Exchange exchange) {
        return BindingBuilder.bind(queue).to(exchange).with("inform.#.sms.#").noargs();
    }

    @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("inform.#.email.#").noargs();
    }




}

4.生产者

package com.rabbitmq.demo.mq;


import com.rabbitmq.demo.conf.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 JiangBeiPing
 * @Date 2020/1/13 12:18
 * @Version 1.0
 **/
@SpringBootTest
@RunWith(SpringRunner.class)
public class Producer_topics {

    @Autowired
    RabbitTemplate rabbitTemplate;

    @Test
    public void testSend(){
        for (int i = 0; i < 5; i++) {
            String message = "生产者发送消息："+i;
            rabbitTemplate.convertAndSend(RabbitmqConfig.EXCHANGE_TOPICS_INFORM,"inform.sms.email",message);
            System.out.println("生产者发送消息:'" + message + "'");
        }

    }

}

5.监听配置

package com.jbp.controller;

import com.jbp.conf.RabbitmqConfig;
import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * @Author JiangBeiPing
 * @Date 2020/1/13 12:24
 * @Version 1.0
 **/
@Component
public class ReceiveHandler {

    //监听email队列
    @RabbitListener(queues = {RabbitmqConfig.QUEUE_INFORM_EMAIL})
    public void receive_email(String msg, Message message, Channel channel){
        System.out.println(msg);
    }

    //监听sms队列
    @RabbitListener(queues = {RabbitmqConfig.QUEUE_INFORM_SMS})
    public void receive_sms(String msg,Message message,Channel channel){
        System.out.println(msg);
    }

}

6.测试

编写过程中多次测试名字后缀可能会有变化
