All Implemented Interfaces:

FieldResolver

Direct Known Subclasses:

CachedDTOAwareFieldResolver

public class DTOAwareFieldResolver
extends Object
implements FieldResolver

FieldResolver implementation that treats a DTO type as the public query contract and maps DTO selector paths to entity selector paths.

Resolution proceeds in three steps:

• Resolve the incoming path against the DTO class structure.
• Translate the DTO path to an entity path using MapsTo, then verify that the resulting entity path exists.
• Return the mapped entity path together with the terminal DTO field so callers can apply validation separately.
