public interface ResourceLoader
org.springframework.context.ApplicationContext
is required to provide this functionality plus extended
ResourcePatternResolver support.
DefaultResourceLoader is a standalone implementation that is
usable outside an ApplicationContext and is also used by ResourceEditor.
Bean properties of type Resource and Resource[] can be populated
from Strings when running in an ApplicationContext, using the particular
context's resource loading strategy.

Resource getResource(String location)
Resource handle for the specified resource location.
The handle should always be a reusable resource descriptor,
allowing for multiple InputStreamSource.getInputStream() calls.
Note that a Resource handle does not imply an existing resource;
you need to invoke Resource.exists() to check for existence.

ClassLoader used by this ResourceLoader.
Clients which need to access the ClassLoader directly can do so
in a uniform manner with the ResourceLoader, rather than relying
on the thread context ClassLoader.
