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.
The created Map contains all request parameter name-value pairs. If the method parameter type is MultiValueMap instead, the created map contains all request parameters and all there values for cases where request parameters have multiple values.
