public class MappingMediaTypeFileExtensionResolver
extends Object
implements MediaTypeFileExtensionResolver

An implementation of MediaTypeFileExtensionResolver that maintains lookups between file extensions and MediaTypes in both directions.

Initially created with a map of file extensions and media types. Subsequently subclasses can use addMapping(java.lang.String, cn.taketoday.http.MediaType) to add more mappings.
