[hibernate-issues] [JIRA] (HHH-16463) @PrimaryKeyJoinColumn ignored for @OneToOne mappings

Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZGFhOTZmOTJj... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16463?atlOrigin=eyJpIjoiZGFhOT... ) HHH-16463 ( https://hibernate.atlassian.net/browse/HHH-16463?atlOrigin=eyJpIjoiZGFhOT... ) @PrimaryKeyJoinColumn ignored for @OneToOne mappings ( https://hibernate.atlassian.net/browse/HHH-16463?atlOrigin=eyJpIjoiZGFhOT... ) Change By: Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Given the following mapping: {code:java}@OneToOne @MapsId @PrimaryKeyJoinColumn(name = "id") //ignored! private User user;{code} The column name is simply ignored. There are two possible workarounds: # Remove {{@MapsId}} and add {{optional=false}} (but see *HHH-16464*) : {code:java}@OneToOne(optional = false) @PrimaryKeyJoinColumn(name = "id") private User user;{code} # Use {{@JoinColumn}} instead of {{@PrimaryKeyJoinColumn}} {code:java}@OneToOne @MapsId @JoinColumn(name = "id"){code} But my reading of the JPA spec is that the first example should work.
