All Implemented Interfaces:

FieldResolver

public class CachedDTOAwareFieldResolver

DTOAwareFieldResolver variant that caches DTO-path resolution outcomes.

Successful resolutions are memoized by CacheKey, and a per-key lock is used to avoid duplicate reflective resolution work when multiple threads request the same path concurrently.
