- org.springframework.web.method.annotation.RequestParamMapMethodArgumentResolver

所有已实现的接口:
HandlerMethodArgumentResolver
```
public class RequestParamMapMethodArgumentResolver
extends Object
implements HandlerMethodArgumentResolver
```
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).

    Whether the given method parameter is supported by this resolver.
    指定者:
    supportsParameter 在接口中 HandlerMethodArgumentResolver
    参数:
    parameter - the method parameter to check
    返回:
    true if this resolver supports the supplied parameter; false otherwise

```
    从接口复制的说明: HandlerMethodArgumentResolver
    Resolves a method parameter into an argument value from a given request. A ModelAndViewContainer provides access to the model for the request. A WebDataBinderFactory provides a way to create a WebDataBinder instance when needed for data binding and type conversion purposes.
    指定者:
    resolveArgument 在接口中 HandlerMethodArgumentResolver
    参数:
    parameter - the method parameter to resolve. This parameter must have previously been passed to HandlerMethodArgumentResolver.supportsParameter(org.springframework.core.MethodParameter) which must have returned true.
    mavContainer - the ModelAndViewContainer for the current request
    webRequest - the current request
    binderFactory - a factory for creating WebDataBinder instances
    返回:
    the resolved argument value, or null if not resolvable
    抛出:
    Exception - in case of errors with the preparation of argument values
