public class InvocableHandlerMethod extends HandlerMethod
HandlerMethodArgumentResolver
s.
Argument resolution often requires a WebDataBinder
for data binding or for type
conversion. Use the setDataBinderFactory(WebDataBinderFactory)
property to supply
a binder factory to pass to argument resolvers.
Use setHandlerMethodArgumentResolvers(org.springframework.web.method.support.HandlerMethodArgumentResolverComposite)
to customize the list of argument resolvers.

Argument values are commonly resolved through HandlerMethodArgumentResolver
s.
The providedArgs
parameter however may supply argument values to be used directly,
i.e. without argument resolution. Examples of provided argument values include a
WebDataBinder
, a SessionStatus
, or a thrown exception instance.
Provided argument values are checked before argument resolvers.
