ResourceLoader implementation that resolves paths as ServletContext
resources, for use outside a WebApplicationContext (for example,
in an HttpServletBean or GenericFilterBean subclass).
Within a WebApplicationContext, resource paths are automatically
resolved as ServletContext resources by the context implementation.
