Subject [jira] Commented: (OPENJPA-689) @ID define in super class
Date Wed, 22 Oct 2008 17:45:44 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641917#action_12641917

Fernando commented on OPENJPA-689:
----------------------------------

I am doing this right now.  Did you add the EntityBase to the persistence.xml classes list?
 Since it has to enhance the mappedSuperclass too.

> our entities have share super class,the class has one field define the entity id,so we
define the class as mappedsuperclass
> when we work with hibernate JPA,it work fine.
> but migrate to openjpa,the PCEnhancer don't assign other entity has ID class,so the query
sql is incorrect.
> example:
> @MappedSuperclass
> public EntityBase {
>     @Id
>     @Column(name="ID")
>     private String id;
> }
> @Entity
> public B extends EntityBase {
> }
> @Entity
> public C extends EntityBase {
> }
> Object o = em.find(B.class, "111");
> the sql list:
> select * from A where id=?
> select * from B where id=?
