I have my project set up like this:

And I have my code set up as:
我的代码设置为：

How can I fix this?

What you put directly under src/main/javais in the default package, at the root of the classpath. It's the same for resources put under src/main/resources: they end up at the root of the classpath.
您直接放置src/main/java在默认包中，位于类路径的根目录下。放在 下的资源也是如此src/main/resources：它们最终位于类路径的根目录。
So the path of the resource is app-context.xml, not main/resources/app-context.xml.
所以资源的路径是app-context.xml，不是main/resources/app-context.xml。

Try this:
尝试这个：
ApplicationContext context = new ClassPathXmlApplicationContext("app-context.xml");

The file location/path has to relative to your classpath locations. If resources directory is in your classpath you just need "app-context.xml" as file location.
文件位置/路径必须相对于您的类路径位置。如果资源目录在您的类路径中，您只需要“app-context.xml”作为文件位置。

We can also try this solution
我们也可以试试这个解决方案
ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:app-context.xml");
in this the spring automatically finds the class in the class path itself
在这种情况下，spring 会自动在类路径本身中找到该类
