Strategy interface for loading resources (e.. class path or file system resources). An ApplicationContext is required to provide this functionality, plus extended ResourcePatternResolver support.
Bean properties of type Resource and Resource array can be populated from Strings when running in an ApplicationContext, using the particular context's resource loading strategy.
Expose the 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.
Return a Resource handle for the specified resource. The handle should always be a reusable resource descriptor, allowing for multiple Resource#getInputStream() calls.
Note that a Resource handle does not imply an existing resource; you need to invoke Resource#exists to check for existence.
