Spring JPA Hibernate Oracle #OneToOne with Shared Primary Key fails on insert - foreign key violation - spring

Question

I have 2 Entities that I am trying to set up using a #OneToOne relationship.
I am using Oracle 11g as the database and User Table has a generated ID via a sequence. This Id from the user table is the Primary Key and Foreign key in the UserProfile table.
So basically a User is mapped to 1 and only 1 User Profile and a User Profile maps back to only 1 User.
I have seeded data in my database and I can read User Object with a User Profile without problem. But when I try to insert a new User Object with a New UserProfile object in a transaction it fails with a Foreign Key Violation in my UserProfile table.
It seems to be a common problem out there with a #OneToOne with Shared primary key, but I can't see to find a answer that works. Can someone point me in the right direction?
I can see that the Id in USerProfile gets set correctly, just on the commit to the database it throws the violation. It almost seems like the UserProfile is being committed to the database before User. Is there a way to persist the User first without have to persist these objects separately?
Here are my entities:

Answer 1

Your mapping is wrong. In a bidirectional asociation, one side is the owner of the association, and tells how the association is mapped. The other side is the inverse side, and just says "look at the other side for the mapping" using the mappedBy attribute.
See the documentation for an exemple:
#Entity
class UserProfile {
#Id Integer id;
#MapsId #OneToOne
#JoinColumn(name = "user_id")
User user;
}
#Entity
class Person {
#Id #GeneratedValue
Integer id;
#OneToOne(mappedBy = "user")
private UserProfile profile;
}
