## 接口 ResolvableTypeProvider

-     public interface ResolvableTypeProvider

  Any object can implement this interface to provide its actual `ResolvableType`.

  Such information is very useful when figuring out if the instance matches a generic signature as Java does not convey the signature at runtime.

  Users of this interface should be careful in complex hierarchy scenarios, especially when the generic type signature of the class changes in sub-classes. It is always possible to return `null` to fallback on a default behavior.
