Spring AMQP和两个RabbitMQ服务器之间的换位(Spring AMQP and conmutation between two RabbitMQ servers)

 我有一个项目，我使用Spring AMQP。 我有两个SimpleMessageListenerContainer，一个是服务器（amq-gen）自行声明的队列，另一个是具有给定名称的队列。 我使用SimpleRoutingConnectionFactory和两个CachingConnectionFactory。 对于错误检测，我有一个ConnectionListener，ListenerContainerConsumerFailedEvent和一个ConditionalExceptionLogger。  
 一旦在AMQP连接中检测到错误，想法是在两个Rabbit服务器之间切换，但是当AMQP连接中存在错误时，ConditionalExceptionLogger中会抛出几个错误，类型为ListenerContainerConsumerFailedEvent类型的几个事件，并使自动切换的事实复杂化在服务器之间  
 在多次重试的情况下，自动切换的最佳方法是什么？  
 谢谢 

I have a project in which I use Spring AMQP. I have two SimpleMessageListenerContainer, one with a self-declared queue by the server (amq-gen), and one with a queue with a given name. I use a SimpleRoutingConnectionFactory with two CachingConnectionFactory. For error detection I have a ConnectionListener, ListenerContainerConsumerFailedEvent, and a ConditionalExceptionLogger. 
The idea is to switch between two Rabbit servers once an error is detected in the AMQP connection, but when there is an error in the AMQP connection several errors are thrown in the ConditionalExceptionLogger, several events of type ListenerContainerConsumerFailedEvent, and complicates the fact of switching automatically Between servers. 
What could be the best way to do that switching automatically given a number of retries? 
Thank you

 我用以下指令解决了它：  
app.directive('mediaelem', function($timeout) {
  return {
    restrict: 'A',
    link: function(scope, element) {
       $timeout(function(){
         var eventAudio  = document.querySelector('.audiocontainer').getAttribute('data-audio');
         $(element).attr('src', eventAudio).mediaelementplayer();
       }, 500);
    }
  };
});
 
 我省略了我用于音频标签的指令，并使用上面的指令，如下所示：  
<div ng-repeat="audio in event.audios">
    <div class="audiocontainer" data-audio="data/events/{{event.id_evento}}/recursos/audio/{{audio}}">
      <audio controls src="" mediaelem>
    </div>
</div>
 
 它没有任何问题。 

I solved it with the following directive: 
app.directive('mediaelem', function($timeout) {
  return {
    restrict: 'A',
    link: function(scope, element) {
       $timeout(function(){
         var eventAudio  = document.querySelector('.audiocontainer').getAttribute('data-audio');
         $(element).attr('src', eventAudio).mediaelementplayer();
       }, 500);
    }
  };
});
 
I omited the directive I was using for the audio tag and used the directive above like this: 
<div ng-repeat="audio in event.audios">
    <div class="audiocontainer" data-audio="data/events/{{event.id_evento}}/recursos/audio/{{audio}}">
      <audio controls src="" mediaelem>
    </div>
</div>
 
It works without any problems.
