public class RequestParamMapMethodArgumentResolver
extends HandlerMethodArgumentResolverSupport
implements SyncHandlerMethodArgumentResolver

Resolver for Map method arguments annotated with @RequestParam where the annotation does not specify a request parameter name. See RequestParamMethodArgumentResolver for resolving Map method arguments with a request parameter name.
