RabbitHandler建立消费者和春季的致命异常重试队列倾听的RabbitMQ(RabbitHa

我使用Spring AMQP RabbitHandler，并写了下面的代码： -

@RabbitListener(queues = "#{testQueue.name}")
public class Tut4Receiver {

  @RabbitHandler
  public void receiveMessage(String message){
       System.out.println("Message received "+message);
  }
}

也队列的定义如下： -

@Bean
public Queue testQueue() {
    return new AnonymousQueue();
}

我使用单独的代码初始化连接工厂。

我的问题是，如果RabbitMQ的是下跌了一段时间，它不断重试创建一个消费者，但只有当它临危一个ConnectionRefused错误。但是，假如用户没有在RabbitMQ的存在，有其新的用户将产生的缝隙，然后将其从RabbitMQ的收到一个致命错误，它永远不会重试由于该结果是自动删除队列将兔MQ创建没有任何消费者。

甚至任何方式重试致命的异常，如用户不存在？

验证失败被认为是默认致命的，而不是重试。

您可以通过监听器容器（上设置属性覆盖此行为possibleAuthenticationFailureFatal ）。该物业是不是可以作为一个引导属性，所以你必须替换启动的容器厂...

    @Bean(name = "rabbitListenerContainerFactory")
    public SimpleRabbitListenerContainerFactory simpleRabbitListenerContainerFactory(
            SimpleRabbitListenerContainerFactoryConfigurer configurer, ConnectionFactory connectionFactory) {

        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        factory.setContainerConfigurer(smlc -> smlc.setPossibleAuthenticationFailureFatal(false));
        return factory;
    }
