Default Conversions and Converters
EclipseLink defines the following converter annotations and XML attributes (in addition to JPA-defined ones):
- @Converter and <converter>
- @TypeConverter and <type-converter>
- @ObjectTypeConverter and <object-type-converter>
- @StructConverter and <struct-converter>
- @Convert and <convert>
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
For more information, see Section 8.1 "Entity" in the JPA Specification.
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.
