public class ClassPathResource extends AbstractFileResolvingResource
Resource implementation for class path resources.
Uses either a given ClassLoader or a given Class for loading resources.
Supports resolution as java.io.File if the class path
resource resides in the file system, but not for resources in a JAR.
Always supports resolution as URL.
