随手撸一个Spring 整合RabbitMQ的简单案例

搭建Spring Boot环境

我们选择基于Spring-Rabbit去操作RabbitMQ

使用spring-boot-starter-amqp会自动添加spring-rabbit依赖，如下：

<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>

配置

1. 配置application.yml
   配置连接rabbitmq的参数

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

2. 定义RabbitConfig类，配置Exchange、Queue、及绑定交换机。
   本例配置Topic交换机

package com.zthero.test.rabbitmq.config;

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

/**
 * @Auther: 洺润Star
 * @Date: 2019/12/25 20:31
 * @Description:
 */
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();
    }

}

生产端

使用RarbbitTemplate发送消息

package com.zthero.test.rabbitmq;

import com.zthero.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;

/**
 * @Auther: 洺润Star
 * @Date: 2019/12/25 20:54
 * @Description:
 */
@SpringBootTest
@RunWith(SpringRunner.class)
public class Producer05_topics_springboot {
    @Autowired
    RabbitTemplate rabbitTemplate;
    @Test
    public void testSendByTopics(){
        for (int i=0;i<5;i++){
            String message = "sms email inform to user"+i;
            rabbitTemplate.convertAndSend(RabbitmqConfig.EXCHANGE_TOPICS_INFORM,"inform.sms.email",message);
            System.out.println("Send Message is:'" + message + "'");
        }
    }
}

消费端

创建一个消费端工程，添加倚赖

<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>

使用@RabbitListener注解监听队列

package com.zthero.test.rabbitmq;

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

/**
 * @Auther: 洺润Star
 * @Date: 2019/12/25 20:56
 * @Description:
 */
@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);
    }
}

测试

1. 启动生产端
2. 启动消费端，启动类启动过程中会自动加载消费类，打印日志如下
   
   也可以使用页面管理工具进行常看
