Message Title

While working on a different issue, we found out that the mapping model assumes that the ParkingSpot#assignedTo association refers to the primary key of Employee, even though the @JoinColumn explicitly specifies the referencedColumnName to be something other than the primary key.

This is just a synthetic model that we thought about, and I think the workaround to use mappedBy should be good enough, but I wanted to capture it anyway.

@Entity(name = "Employee")
public static class Employee {
	@Id
	int id;

	String name;

	@Embedded
	LocationDetails location;
}

@Embeddable
public static class LocationDetails {
	int officeNumber;

	@OneToOne
	ParkingSpot parkingSpot;
}

@Entity(name = "ParkingSpot")
public static class ParkingSpot {
	@Id
	//int id;
	Integer id;

	String garage;

	@OneToOne
	// Case 1, with maps id
	@MapsId
	@JoinColumn(name = "id", referencedColumnName = "parking_spot_id")
	// Case 2, with explicit config of what @MapsId does behind the scenes
	//@JoinColumn(name = "id", referencedColumnName = "parking_spot_id", insertable = false, updatable = false)
	//@NotFound(action = NotFoundAction.IGNORE)
	Employee assignedTo;
}
