Java: Hibernate @OneToOne mapping

Question

I\'m trying to get Hibernate @OneToOne annotations working and not having much success here...

Let\'s say I\'ve got a table called status that looks lik

Answer 1

use this way. Add below field in Customer entity.

@OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "customer")
private Status status;

and don't add getter and setter for status field in Customer entity. And add below code to Status Entity.

@OneToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "customer_id", nullable = false)
private Customer customer;

Here add the getter and setter for customer field in Status Entity class. You can see one working example here.

Answer 2

Your Status entity must not have properties userId and contentId of type Integer, mapped with @Column. It must have properties user and content of type User and Content, mapped with @OneToOne:

public class User {
    @OneToOne(mappedBy = "user")
    private Status status;
    // ...
}

public class Status {
    @OneToOne
    @JoinColumn(name = "frn_user_id")
    private User user;
    // ...
}

A user has one status. A status has one user.
