无法打开类路径资源，因为它不存在

Question

我正在通过阅读一本书来学习REST服务，这是第一个使用bean的练习。我创建了一个bean配置文件（applicationContext.xml）并将其放在/ spring文件夹中，但是当我运行应用程序时它说它无法找到它（如下图所示）：

有人知道我做错了什么吗？

Answer 1

您可以将spring文件夹移动到src / main / resources文件夹中以便拥有 src / main / resources / spring / applicationContext.xml？

Answer 2

由于您的spring是源文件夹，因此您可以直接引用它。源目录中的资源将直接添加到类路径中。

将您的配置 web.xml 更改为：

<param-value>
   classpath:applicationContext.xml
</param-value>
