驗證失敗彈簧AMQP超時

Question

我的消費約一週工作正常，那麼消費者線程死亡，記錄了以下錯誤：

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

目標代碼如下：

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

所以，連接的問題的確並非必須與認證有關。

還有ShutdownSignalException由Connection timed out原因。

因此，您應該嘗試增加連接超時，默認爲60000。

但是，由於我們無法連接，所以代理上的資源可能存在一些問題。

我們不能將這種錯誤（ShutdownSignalException）視爲非致命的，因爲您的問題恰好發生在start()上。

EDIT

在致命故障的情況下，容器發射ListenerContainerConsumerFailedEvent：http://docs.spring.io/spring-amqp/reference/html/_reference.html#consumer-events。您可以處理它並故意重新啓動容器。
