Little more info. The generated property is coming from
BinderHelper.createSyntheticPropertyReference as called from
org.hibernate.cfg.ToOneFkSecondPass#doSecondPass
The mappings in question here are:
public class Company {
@Id
@Column(name = "entity_id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator =
"SEQ_STORE")
private Long id = null;
@Column(name = "id", nullable = false, unique = true, updatable =
false)
private Long companyId = null;
...
}
public class Person {
...
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "relation_id", referencedColumnName = "id")
private Company company = null;
}
The binder code is creating a synthetic component property on Company
presumably (?) to act as the FK target for this ManyToOne. Is that the
correct reading of what is going on? I have no clue what is a valid use
case for doing this so I am largely making an educated guess at what is
going on here.
Lets assume that this "synthetic property is needed"... In that case
I'd then say that it seems to me we need to create it in such a manner
that it is distinguishable from a "real" property so that it can later
be excluded during the @StaticMetamodel binding process (very much like
we do already for back-refs).
To that end I committed a change that resolved this for the test case
submitted by Andreas to HHH-4870. It caused no regressions.
On related topic, anyone have thoughts on good way to test this
@StaticMetamodel binding code?
