springboot整合Rabbitmq

学习笔记：

springboot整合Rabbitmq,（整合rabbitmq中的topics模式）

生产者的配置信息：
-----------------------------------------------------------------------------------------
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();
    }

    //声明队列 QUEUE_INFORM_EMAIL

    @Bean(QUEUE_INFORM_EMAIL)
    public Queue QUEUE_INFORM_EMAIL(){
        return new Queue(QUEUE_INFORM_EMAIL);
    }

    //声明队列 QUEUE_INFORM_EMAIL

    @Bean(QUEUE_INFORM_SMS)
    public Queue QUEUE_INFORM_SMS(){
        return new Queue(QUEUE_INFORM_SMS);
    }

    //绑定交换机和队列,指定routingKey

    //绑定QUEUE_INFORM_EMAIL

    @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();
    }


    //绑定QUEUE_INFORM_SMS

    @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(ROUTINGKEY_SMS).noargs();
    }
}

生产者发送消息

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;

@SpringBootTest
@RunWith(SpringRunner.class)
public class Topics {

    @Autowired
    RabbitTemplate rabbitTemplate;

    //使用rabbitmqTemplate发送消息
    @Test
    public void testSendEmail(){

        String message="发送消息给消费者------";

        /**
         *  1.交换机名称
         *  2.routingKey
         *  3.消息内容
         */
        rabbitTemplate.convertAndSend(RabbitmqConfig.EXCHANGE_TOPICS_INFORM,"inform.email",message);
    }
}
-----------------------------------------------------------------------------------------

消费者的配置文件:(与生产者的一样)

消费者监听信息：

import com.rabbitmq.client.Channel;
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;

@Component
public class ReceiveHandler {

    @RabbitListener(queues = {RabbitmqConfig.QUEUE_INFORM_EMAIL})
    public void send_email(String msg, Message message, Channel channel){

        System.out.println("接受到的消息是： "+msg);
    }
}
-----------------------------------------------------------------------------------------

生产者与消费者的 application.yml

server:
  port: 50001 
spring:
  application:
    name: test-rabbitmq-producer
    rabbitmq:
      host: 127.0.0.1
      username: guest  #RabbitMq的默认用户名
      password: guest  #RabbitMq的默认密码
      virtualHost: /   #RabbitMq的虚拟主机
