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}}:
{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. |
