A specialized implementation of FileLocationStrategy which tries to construct a file path from the locator's base path and file name.

This strategies ignores the URL stored in the passed in FileLocator. It generates a path by concatenating the base path (if present) and the file name. If the resulting path points to a valid file, the corresponding URL is returned.
