消费者

public class SpringQueueListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        //打印消息
        System.out.println(new String(message.getBody()));
    }
}



public class FanoutListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        //打印消息
        System.out.println(new String(message.getBody()));
    }
}


public class TopicListenerWell implements MessageListener {
    @Override
    public void onMessage(Message message) {
        //打印消息
        System.out.println(new String(message.getBody()));
    }
}

// 消费者启动
public class Test {

    public static void main(String[] args) {
        //初始化IOC容器
        ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath:spring-rabbitmq-consumer.xml");

    }
}

Spring boot 整合RabbitMQ

引入依赖

配置类application.yml

# 配置RabbitMQ的基本信息  ip 端口 username  password..
spring:
  rabbitmq:
    host:  # ip
    port: 5672
    username: admin
    password: handhand
    virtual-host: /api

定义交换机，队列以及绑定关系的配置类

@Configuration
public class RabbitMqConfig {

    //定义交换机的名字
    public static final String  EXCHANGE_NAME = "boot_topic_exchange";
    //定义队列的名字
    public static final String QUEUE_NAME = "boot_queue";

    //1、声明交换机
    @Bean("bootExchange")
    public Exchange bootExchange(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }

    //2、声明队列
    @Bean("bootQueue")
    public Queue bootQueue(){
        return QueueBuilder.durable(QUEUE_NAME).build();
    }

    //3、队列与交换机进行绑定
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue, @Qualifier("bootExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }

}

注入RabbitTemplate，调用方法，完成消息发送

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

     //注入 RabbitTemplate
    @Autowired
     private RabbitTemplate  rabbitTemplate;

     @Test
     public void send(){
         rabbitTemplate.convertAndSend("boot_topic_exchange","boot.haha","boot mq...");
     }
}

消费者监听

@Component
public class RabbitMQListener {

      //定义方法进行信息的监听   RabbitListener中的参数用于表示监听的是哪一个队列
      @RabbitListener(queues = "boot_queue")
      public void ListenerQueue(Message message){
          System.out.println("message:"+message.getBody());
      }
}
