类 RequestParamMapMethodArgumentResolver

java.lang.Object

cn.taketoday.web.bind.resolver.RequestParamMapMethodArgumentResolver

所有已实现的接口:

ParameterResolvingStrategy

public class RequestParamMapMethodArgumentResolver
extends Object
implements ParameterResolvingStrategy

Resolves Map method arguments annotated with an @RequestParam where the annotation does not specify a request parameter name.

The created Map contains all request parameter name/value pairs, or all multipart files for a given parameter name if specifically declared with MultipartFile as the value type. If the method parameter type is MultiValueMap instead, the created map contains all request parameters and all their values for cases where request parameters have multiple values (or multiple multipart files of the same name).
