搭建SpringBoot环境

添加spring-rabbit依赖

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

application.yml 配置文件

server:
  port: 12000
spring:
  application:
    name: rabiitmq-producer
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    virtualHost: /

创建config类

@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";
    
    // 声明交换机
    @Bean(EXCHANGE_TOPICS_INFORM)
    public Exchange EXCHANGE_TOPICS_INFORM() {
        //DURABLE(true) 持久化，消息队列重启后交换机仍然存在
        return ExchangeBuilder.topicExchange(EXCHANGE_TOPICS_INFORM)
                .durable(true).build();
    }
    
    // 声明队列
    @Bean(QUEUE_INFORM_SMS)
    public Queue QUEUE_INFORM_SMS(){
        Queue queue = new Queue(QUEUE_INFORM_SMS);
        return queue;
    }
    @Bean(QUEUE_INFORM_EMAIL)
    public Queue QUEUE_INFORM_EMAIL(){
        Queue queue = new Queue(QUEUE_INFORM_EMAIL);
        return queue;
    }
    
    // 队列绑定交换机
        @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("inform.#.sms.#").noargs();
    }
    @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("inform.#.email.#").noargs();
    }
}

生产者

使用RabbitTemplate发送消息

@SpringBootTest
@RunWith(SpringRunner.class)
public class Producer05_Topics_Springboot {
    @Autowired
    RabbitTemplate rabbitTemplate;
    @Test
    public void testSendByTopics(){
        String message = "这是一条消息";
        rabbitTemplate.convertAndSend(RabbitmqConfig.EXCHANGE_TOPICS_INFORM,"inform.sms.email",message);
    }
}

消费者

@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("receive: "+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("receive: "+msg);
    }

}
