 Description  « Hide

I repeatedly find myself annotating my JPA entities with the very same set of annotations:

class Person {


If both @Entity and @EntityListener were allowed to be used as meta-annotations I could collapse them into:

@interface @AuditedEntity {


Resulting in:

class Person {


This is in line with the meta-annotation handling CDI exposes to introduce annotation with richer semantics in annotation code. The following changes would be required.

  • Add ElementType.ANNOTATION_TYPE to the relevant annotations
  • Specify that persistence providers have to evaluate the annotations from the meta-level as well using the first one found, so that locally defined annotations would be considered first.
