Annotation Interface NaturalIdCache

@Target(TYPE)@Retention(RUNTIME)public @interfaceNaturalIdCache
Specifies that mappings from the natural id values of the annotated entity to the corresponding entity id values should be cached in the shared second-level cache. This allows Hibernate to sometimes avoid round trip to the database when a cached entity is retrieved by its natural id.

This annotation is usually used in combination withCache, since a round trip may only be avoided if the entity itself is also available in the cache.
