    • Method Detail

      • protected Resource convertClassLoaderURL(java.net.URL url)

        Convert the given URL as returned from the ClassLoader into a Resource object.

        The default implementation simply creates a UrlResource instance.

      • protected java.lang.String determineRootDir(java.lang.String location)

        Determine the root directory for the given location.

        Used for determining the starting point for file matching, resolving the root directory location to a java.io.File and passing it into retrieveMatchingFiles, with the remainder of the location as pattern.

        Will return "/WEB-INF/" for the pattern "/WEB-INF/*.xml", for example.

        Parameters:
        location - the location to check
