  InitBinderDataBinderFactory | Adds initialization to a WebDataBinder via `@InitBinder` methods.
  MapMethodProcessor | Resolves `Map` method arguments and handles `Map` return values.
  ModelAttributeMethodProcessor | Resolves method arguments annotated with `@ModelAttribute` and handles return values from methods annotated with `@ModelAttribute`.
