Add a MappingDefaults option allowing for multiple fields of the same
Embeddable object in an entity
----------------------------------------------------------------------------------------------------
Key: OPENJPA-479
URL: https://issues.apache.org/jira/browse/OPENJPA-479
Project: OpenJPA
Issue Type: New Feature
Reporter: Ron Pressler
Priority: Minor
Currently, having multiple fields of the same Embeddable type in an entity
requires the use of the AttributeOverride annotation, so that the column name
of the different fields won't clash. This is tiresome.
It would be helpful to have a MappingDefault option that would prefix the
embedded field's column name with the field name.
For example:
@Embeddable
class Em {
int foo;
}
@Entity
class En {
Em first;
Em second;
}
Would create table EN with columns FIRST_FOO, SECOND_FOO.
