我试图寻找我的问题的解决方案，但找不到它堆栈溢出。

问题当用户尝试声明队列或交换时，在RabbitMQ服务器出现问题的极端情况下，客户端会保持等待，而不会出现任何超时，这会导致调用rabbitmq的线程始终处于等待状态（等待永不结束）。

下面是堆栈跟踪

任何帮助都将不胜感激。队列的声明目前在我的bean的postconstruct中调用我们处理消息的组件，因此不允许任何新的bean创建。

更新这个问题在我们的产品服务器上再次出现。当尝试直接通过amqp-client-3.4.2连接时，它似乎可以工作。但是从spring-rabbit-1.6.7.RELEASE，spring-amqp-1.6.7.RELEASE它不能工作。

通过amqp客户端-3.4.2

ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("<<HOST NAME>>");
        factory.setUsername("<<USERNAME>>");
        factory.setPassword("<<PASSWORD>>");
        factory.setVirtualHost("<<VIRTUAL HOST>>");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.queueDeclare(QUEUE_NAME, true, false, false, null);

Code flow with rabbit-amqp client
不工作的Spring方式

CachingConnectionFactory factory = new CachingConnectionFactory();
        factory.setHost("<<HOST NAME>>");
        factory.setUsername("<<USERNAME>>");
        factory.setPassword("<<PASSWORD>>");
        factory.setVirtualHost("<<VIRTUAL HOST>>");

        RabbitAdmin admin = new RabbitAdmin(factory);
        Queue queue = new Queue(QUEUE_NAME);
        admin.declareQueue(queue);

这个问题很少发生，我们仍在试图找出此行为背后的原因。我们尝试设置连接超时，但在我们的测试程序中不起作用。
在进一步调试时，看起来像是一个异常没有让通知发送回我们的代码。对于客户端未找到这类问题，我们正确地获得了异常。
我们在CentOS Linux 7（内核）上使用RabbitMQ 3.6.10和Erlang 19.3.4
