SpringBoot整合RabbitMQ超级详细教程

首先最重要的是思路：SpringBoot整合RabbitMQ可分为生产者工程与消费者工程分为以下几步

生产者工程
1）添加RabbitMQ的起步依赖
2）在application.yml中配置RabbitMQ的信息
3）创建一个rabbitMQ配置类
4）创建生产者

消费者工程
1）添加RabbitMQ的起步依赖
2）在application.yml中配置RabbitMQ的信息
3）创建一个rabbitMQ配置类
4）消费者工程

生产者工程开始

1）添加RabbitMQ的起步依赖

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

2）在application.yml中配置RabbitMQ的信息

server:
  port: 8081
spring:
  application:
    name: test-rabbitmq-producer
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    virtualHost: /

3）创建一个rabbitMQ配置类，配置Exchange、Queue、及绑定交换机。
本例配置Topic交换机。

package com.example.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;

/**
 * @ClassName RabbitmqConfig
 * @Description TODO
 * @Author 胡泽
 * @Date 2019/12/17 12:35
 * @Version 1.0
 */
@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();
    }

}

4）创建生产者

使用RarbbitTemplate发送消息

package com.example;

import com.example.config.RabbitmqConfig;
import org.junit.jupiter.api.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;

@SpringBootTest
@RunWith(SpringRunner.class)
class ProdcerTopicsSpringbootApplicationTests {
    @Autowired
    RabbitTemplate rabbitTemplate;

    @Test
    public void Producer_topics_springbootTest() {

        //使用rabbitTemplate发送消息
        String message = "send email message to user";
        /**
         * 参数：
         * 1、交换机名称
         * 2、routingKey
         * 3、消息内容
         */
        rabbitTemplate.convertAndSend(RabbitmqConfig.EXCHANGE_TOPICS_INFORM, "inform.email", message);

    }


}

生产者工程结束

消费者工程开始

1.）起步依赖

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

2.）配置application.yml

server:
  port: 8082
spring:
  application:
    name: test-rabbitmq-consumer
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    virtualHost: /

3.）创建一个rabbitMQ配置类

package com.example.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;

/**
 * @ClassName RabbitmqConfig
 * @Description TODO
 * @Author 胡泽
 * @Date 2019/12/17 12:35
 * @Version 1.0
 */
@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();
    }

}

4）监听队列，接收消息

package com.example.controller;

import com.example.config.RabbitmqConfig;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.impl.AMQImpl;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;

import org.springframework.boot.autoconfigure.amqp.RabbitProperties;
import org.springframework.stereotype.Component;

/**
 * @ClassName ReceiveHandler
 * @Description TODO
 * @Author 胡泽
 * @Date 2019/12/17 13:02
 * @Version 1.0
 */
@Component
public class ReceiveHandler {
    //监听email队列
    @RabbitListener(queues = {RabbitmqConfig.QUEUE_INFORM_EMAIL})
    public void receive_email(Object msg, Message message, Channel channel){
        System.out.println("QUEUE_INFORM_EMAIL msg"+msg);
    }
   //监听sms队列
    @RabbitListener(queues = {RabbitmqConfig.QUEUE_INFORM_SMS})
    public void receive_sms(Object msg, Message message, Channel channel){
        System.out.println("QUEUE_INFORM_SMS msg"+msg);
    }
}
