java.lang.IllegalArgumentException : ResourceLoader must not be null in Spring

Question

我想运行https://github.com/spring-projects/spring-security-kerberos在我的机器上(通过 Intellij idea)。我尝试构建和运行的模块是 sec-server-spnego-form-auth，但我不断收到 java.lang.IllegalArgumentException: ResourceLoader 不得为 null 作为以及java.lang.IllegalStateException:ApplicationEventMulticaster未初始化 - 在通过上下文多播事件之前调用“刷新”，我猜这是因为第一个错误而出现的。

你知道这里可能出了什么问题吗？

好吧，我只是通过只使用我需要的模块并将其复制到一个新项目来解决它。另外，我必须使用 application.properties 而不是 .yml 文件，它的效果非常好。

不是最好的解决方案，但它有效。
