1.1 搭建SpringBoot環(huán)境

我們選擇基于Spring-Rabbit去操作RabbitMQ

https://github.com/spring-projects/spring-amqp
使用spring-boot-starter-amqp會自動添加spring-rabbit依賴茵休，

1.2配置

1驱闷、配置application.yml
配置連接rabbitmq的參數(shù)

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

2鲤妥、定義RabbitConfig類怕敬，配置Exchange蔚鸥、Queue斗埂、及綁定交換機塞琼。
本例配置Topic交換機坎炼。

@Configuration
public class RabbitConfig {
    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.#";

    //聲明交換機
    @Bean(EXCHANGE_TOPICS_INFORM)
    public Exchange EXCHANGE_TOPICS_INFORM(){
        //durable(true) 持久化愧膀，mq重啟之后交換機還在
        return ExchangeBuilder.topicExchange(EXCHANGE_TOPICS_INFORM).durable(true).build();
    }

    //聲明QUEUE_INFORM_EMAIL隊列
    @Bean(QUEUE_INFORM_EMAIL)
    public Queue QUEUE_INFORM_EMAIL(){
        return new Queue(QUEUE_INFORM_EMAIL);
    }
    //聲明QUEUE_INFORM_SMS隊列
    @Bean(QUEUE_INFORM_SMS)
    public Queue QUEUE_INFORM_SMS(){
        return new Queue(QUEUE_INFORM_SMS);
    }
     // 每個消費者監(jiān)聽自己的隊列，并且設(shè)置routingkey谣光。
    //生產(chǎn)者將消息發(fā)給交換機檩淋，由交換機根據(jù)routingkey來轉(zhuǎn)發(fā)消息到指定的隊列
    //ROUTINGKEY_EMAIL隊列綁定交換機，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隊列綁定交換機萄金，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();
    }


}

1.3 生產(chǎn)端

@SpringBootTest
@RunWith(SpringRunner.class)
public class Producer04_topics_Boot {
    @Autowired
    RabbitTemplate rabbitTemplate;

    //使用rabbitTemplate發(fā)送消息
    @Test
    public void testSendEmail(){

        String message = "send email message to user";
        /**
         * 參數(shù)：
         * 1蟀悦、交換機名稱
         * 2、routingKey
         * 3氧敢、消息內(nèi)容
         */
        rabbitTemplate.convertAndSend(RabbitConfig.EXCHANGE_TOPICS_INFORM,"inform.email",message);

    }

1.4消費端

目錄結(jié)構(gòu)與生產(chǎn)者一樣

使用@RabbitListener注解監(jiān)聽隊列日戈。

@Component
public class ReceiveHandler {

    @RabbitListener(queues = {RabbitConfig.QUEUE_INFORM_EMAIL})
    public void emil(String msg, Message message , Channel channel){
        System.out.println(msg);
    }
}
