验证失败弹簧AMQP超时

Question

我的消费约一周工作正常，那么消费者线程死亡，记录了以下错误：

It seems the Authentication failure is caused by BufferedInputStream.read timeout, and I want to know if there is a way to treat the Authentication failure as a non-fatal and do not kill the consumer thread. and I think the timeout issue is just caused by network issue not the Authentication failure, since this consumer already worked for one week.

Answer 1

目标代码如下：

} catch (ShutdownSignalException e) { 
... 
    throw new PossibleAuthenticationFailureException(e); 
} 

所以，连接的问题的确并非必须与认证有关。

还有ShutdownSignalException由Connection timed out原因。

因此，您应该尝试增加连接超时，默认为60000。

但是，由于我们无法连接，所以代理上的资源可能存在一些问题。

我们不能将这种错误（ShutdownSignalException）视为非致命的，因为您的问题恰好发生在start()上。

EDIT

在致命故障的情况下，容器发射ListenerContainerConsumerFailedEvent：http://docs.spring.io/spring-amqp/reference/html/_reference.html#consumer-events。您可以处理它并故意重新启动容器。
