ResolvableTypeProvider (Spring Framework 4.3.30.RELEASE API)

所有已知实现类:
PayloadApplicationEvent
```
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.
