(Optional) Used to specify or control the generation of a foreign key constraint for the columns corresponding to the
joinColumns
element when table generation is in effect. If both this element and the
foreignKey
element of any of the
joinColumns
elements are specified, the behavior is undefined. If no foreign key annotation element is specified in either location, the persistence provider's default foreign key strategy will apply.
- Default:
- @ForeignKey(PROVIDER_DEFAULT)
