Spring boot 创建名为'；jmsConnectionFactory'；-NullPointerException-Spring引导Kotlin

我正在编写一个报告服务来接收来自Azure服务总线主题订阅的消息。 我遵循了这个初始指南，只是在我的服务文件中配置了

@JmsListener

，不指定

JmsConnectionFactory

，这样它就会返回默认值，但是这会返回如下所示的错误日志，

JmsConnectionFactory

Bean返回

NullPointerException

随后，我查看了如何配置

jmsConnectionFactory

，以获得指导，因为最初的实现无法运行，但由于仍在返回下面的错误日志，因此没有遇到上述文章中提到的任何建议

然后我在这里对StackOverflow进行了挖掘，发现了这个问题-，然后指向了这个问题-，这导致我在我的

@SpringBootApplication

中排除了

ServiceBusJMSAutoConfiguration:：class

。这确实有效，但我觉得有点奇怪，我需要排除这个类，并且感觉好像还有一些事情我可能做错了

我基本上是在寻找关于我所做的是正常实践还是有更好的方法进行设置的任何见解，因为我并不特别喜欢这个-

@SpringBootApplication（exclude=[ServiceBusJMSAutoConfiguration:：class]）

。在我看来，这似乎是解决一个潜在问题的一种手段。如果您对此有任何帮助/意见，我们将不胜感激
