Spring boot RabbitHandler在Spring中为侦听RabbitMQ的队列创建使用者并重试致命异常

我正在使用Spring AMQP RabbitHandler，并编写了以下代码：

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

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

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停机一段时间，它会继续尝试创建使用者，但只有在它收到

ConnectionRejected

错误时才会这样做。但是，假设用户在RabbitMQ中不存在，并且存在创建新用户的间隙，那么它从RabbitMQ接收到一个致命错误，并且它从不重试，因此结果是在RabbitMQ上创建自动删除队列，而不使用任何使用者

即使在用户不存在等致命异常情况下，是否有重试的方法？

默认情况下，身份验证失败被视为致命的，不会重试

您可以通过在侦听器容器上设置属性（

possibleAuthenticationFailureFailure

）来覆盖此行为。该属性不能作为启动属性使用，因此您必须重写启动的容器工厂

@Bean（name=“rabbitListenerContainerFactory”）
公共SimpleRableBitListenerContainerFactory SimpleRableBitListenerContainerFactory(
SimpleRableBitListenerContainerFactoryConfigurer配置器，连接工厂连接工厂）{
SimpleRableBitListenerContainerFactory=新SimpleRableBitListenerContainerFactory（）；
configurer.configure（工厂、连接工厂）；
factory.SetContainerConfiguration（smlc->smlc.SetPossibleAuthenticationFailureFailure（false））；
返回工厂；
}

有没有在spring rabbit 1.6版上执行此操作的想法？1.6版不再受支持；它的上一次发布是在两年前。1.7.x应该在使用1.6.x的应用程序中工作，没有任何问题（尽管当前版本是2.1.10）。最新的1.7.x版本是1.7.14。
