The JPA spec does not specify a way to override the MapKeyJoinColumn. You
can override the association, like the JoinColumn for a ManyToOne or a
JoinTable for OneToMany.
In your case, maybe it's better to move that association out of the
embeddable.
It's always a good idea to keep the model as simple as possible.

Hi,
We have a problem using @AssociationOverride and @MapKeyJoinColumn and
we would like to have your opinion about this to know if this is an issue.
Here is the test case :
https://github.com/florianlacreuse/hibernate-test-case
Short explanation about the model : an entity with an embeddable field
wrapping a map with an entity as key and a basic type as value.
We use @AssociationOverride to rename the join table (annotation on
embeddable field) and @MapKeyJoinColumn to rename the column related to
the key map (annotation on map field).
Unfortunately, it would seem that the @MapKeyJoinColumn annotation is
ignored. @AssociationOverride may override any other annotations on the
map field ? In this case how to rename the column related to the key map
with the @AssociationOverride ?
Is this an issue or is there any trick we don't know about?
Thanks for your help.
Kind regards,
