javax.persistence.Cacheable - JPA annotation

Annotation Cacheable

Target:
Classes
Specifies whether an entity should be cached if caching is enabled when the value of the persistence.xml caching element is ENABLE_SELECTIVE or DISABLE_SELECTIVE. The value of the Cacheable annotation is inherited by subclasses; it can be overridden by specifying Cacheable on a subclass.

Cacheable(false) means that the entity and its state must not be cached by the provider.
