Java Spring : Why does moving XML file inside the package gives me an error

Question

我是 Java Spring 新手。

我创建了一个名为 com.MyFirstSpringPackage 的包，其中有几个 Java 文件，还有一个 XML 文件(包外部)，它们调用类构造函数(连接 bean)，一切都很顺利。

现在我决定使用 eclipse 通过拖放操作将此 XML 文件推送到包内，然后程序开始抛出错误:

这是堆栈跟踪:

这个错误的原因是什么？为什么我不能将它移到包内，包只是一个文件夹？

您可以尝试使用包名称来引用 xml 文件，例如:

String xmlFile = "com/MyFirstSpringPackage/FirstSprings.xml";
