*Exception persist method Save Attempt to assign child with key
Role(19003) to parent with key User(no-id-yet). Parent keys are immutable
Exception persist method Save Detected attempt to establish User(19004) as
the parent of Role(1) but the entity identified by Role(1) has already been
persisted without a parent. A parent cannot be established or changed once
an object has been persisted.
I want to save user entity with role as a relation entity
*
*public class User{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key id;
@ManyToOne(fetch=FetchType.EAGER,cascade = CascadeType.ALL)
@JoinColumn(name="role_id")
private Role role;
}
i cant save user entity when i assign role to user entity.
