Default Conversions and Converters
EclipseLink defines the following converter annotations (in addition to JPA-defined ones):
EclipseLink persistence provider searches the converter annotations in the following order:
- @Convert
- @Enumerated
- @Lob
- @Temporal
- Serialized (automatic)
You can define converters at the class, field and property level. You can specify EclipseLink converters on the following classes:
- @Entity (see Section 8.1 "Entity" of the JPA Specification)
- @MappedSuperclass
- @Embeddable
You can use EclipseLink converters with the following mappings:
If you specify a converter with any other type of mapping annotation, EclipseLink will throw an exception.
