Java Springs：为什么在包内移动XML文件会给我一个错误

Question

我是Java Springs的新手。

我创建了一个名为com.MyFirstSpringPackage的程序包，其中有几个Java文件，还有一个XML文件（在程序包外部），它们正在调用类构造函数（为bean接线），并且一切正常。

现在我决定使用eclipse拖放将XML文件推送到包中，然后程序开始抛出错误：

这是堆栈跟踪：

此错误的原因是什么？ 为什么我不能将其移动到只是一个文件夹的包装内？

Answer 1

您可以尝试使用包名称来引用xml文件，例如：

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

Answer 2

我遇到了同样的问题，解决方法是使用正斜杠/来提及spring xml文件路径，如下所示：

Resource r = new ClassPathResource("com/ioc/container/resources/springioc.xml");

工作正常。
