Question

我有一个使用RabbitMQ的Spring Boot应用程序。我可以将消息成功发送到队列。我也可以检索消息。但是，当我检索它们时，该消息不会从队列中删除。这样一来，我收到的信息就会一遍又一遍地不断收到相同的邮件列表。

问题

收到邮件后可以删除邮件吗？

代码

接收器 @Component

public class RabbitMQReceiver {

    @Autowired
    private PhotoStatusProcessorService photoStatusProcessorService;

    @RabbitListener(queues = "${rabbitmq.queuename}")
    public void receive(UUID in) {
        System.out.println("Received RabbitMQ msg = " + in);
        photoStatusProcessorService.processPhotoForId(in);
    }
}

配置

@Configuration
public class RabbitMQConfig {

    @Value("${rabbitmq.queuename}")
    String queueName;

//  @Value("${rabbitmq.exchangename}")
//  String exchange;
//
//  @Value("${rabbitmq.routingkeyname}")
//  String routingkey;

    @Bean
    Queue queue() {
        return new Queue(queueName, false);
    }

//  @Bean
//  DirectExchange exchange() {
//      return new DirectExchange(exchange);
//  }
//
//  @Bean
//  Binding binding(Queue queue, DirectExchange exchange) {
//      return BindingBuilder.bind(queue).to(exchange).with(routingkey);
//  }

    @Profile("receiver")
    @Bean
    public RabbitMQReceiver receiver() {
        return new RabbitMQReceiver();
    }
}

application.properties

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=rabbitmq
spring.rabbitmq.password=****
rabbitmq.exchangename=photo-proccessor.exchange
rabbitmq.queuename=photo-proccessor
rabbitmq.routingkeyname=photo-proccessor.routingkey

YML文件

  rabbitmq:
    container_name: rabbitmq
    image: rabbitmq:3.7-management-alpine
    ports:
      - 15672:15672
