java.io.FileNotFoundException: class path resource cannot be opened because it does not exist

问题

I am trying to set the configuration location for my Project but I keep getting the following error:

java.io.FileNotFoundException: class path resource [main/resources/app-context.xml] cannot be opened because it does not exist

I have my project set up like this:

And I have my code set up as:

ApplicationContext context = new ClassPathXmlApplicationContext(configLocation: "main/resources/app-context.xml");

How can I fix this?

回答1:

What you put directly under src/main/java is 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.

So the path of the resource is app-context.xml, not main/resources/app-context.xml.

回答2:

We can also try this solution

ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:app-context.xml");

in this the spring automatically finds the class in the class path itself

回答3:

Try this:

ApplicationContext context = new ClassPathXmlApplicationContext("app-context.xml");

回答4:

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.
