Question

我们的应用程序能够连接到RabbitMQ服务器，消息在消息监听器中收到，一切正常。但是当RabbitMQ重新启动时，我们在日志中得到以下异常，并且在侦听器中没有收到消息。一旦我们重新启动应用程序容器，一切都开始工作。我们无法在Prodcution环境中重新启动我们的应用程序，并且我们希望应用程序能够在RabbitMQ服务器启动后恢复与RabbitMQ的连接。有人可以帮忙。

这个异常对我来说似乎很奇怪，因为如果RabbitMQ拒绝连接，那么当我们重新启动应用程序时，连接是如何建立的。这个问题让我很难过。

1.3.6太旧了，不支持版本。如果您考虑升级到最新版本https://projects.spring.io/spring-amqp/，至少1.7.7，那就太棒了。另请阅读：https://docs.spring.io/spring-amqp/docs/2.0.3.RELEASE/reference/html/_reference.html#auto-recovery。
