关于注解qualifier
注解qualifier

文件目录producer同 consumer

启动类

package com.xuecheng.test.rabbitmq;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @Classname TestRabbitmqApplication
 * @Description TODO
 * @Date 2020/2/21 18:53
 * @Created by mmz
 */
@SpringBootApplication
public class TestRabbitmqApplication {
    public static void main(String[] args) {
        SpringApplication.run(TestRabbitmqApplication.class);
    }
}

配置类

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;

/**
 * @Classname RabbitmqConfig
 * @Description TODO
 * @Date 2020/2/21 18:52
 * @Created by mmz
 */
@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(){
        return ExchangeBuilder.topicExchange(EXCHANGE_TOPICS_INFORM).durable(true).build();
    }
    //声明队列
    @Bean(QUEUE_INFORM_EMAIL)
    public Queue QUEUE_INFORM_EMAIL(){
        return new Queue(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
    //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();
    }
}

生产者

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;

/**
 * @Classname Producer05_topics_springboot
 * @Description TODO
 * @Date 2020/2/21 19:11
 * @Created by mmz
 */
@SpringBootTest
@RunWith(SpringRunner.class)
public class Producer05_topics_springboot {

    @Autowired
    RabbitTemplate rabbitTemplate;

    @Test
    public void testSendEmail(){
        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);
    }
}

消费者

package com.xuecheng.test.rabbitmq.mq;

import com.rabbitmq.client.Channel;
import com.xuecheng.test.rabbitmq.config.RabbitmqConfig;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import sun.plugin2.message.Message;

/**

• @Classname ReceiveHandler
• @Description TODO
• @Date 2020/2/21 19:41
• @Created by mmz
  */
  @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 :” + message);
  }
  }

有一个注解@RabbitListener，监听这个队列
