If you have a relationship like this :
I would write in the Employee entity:
@ManyToOne (cascade=CascadeType.PERSIST)
private Employee supervisor;
@ManyToOne (cascade=CascadeType.PERSIST)
private Department department;
and in the department
@OneToOne (cascade=CascadeType.PERSIST)
private Employee manager;
I then would create and set the variables (name, title, salary, supervisor) of employee
Then I would create the department with his variables (name, code)
With the departments created I then can set the department in the employees
And then I can set the manager in department.
With all the variables set I can persist the entity's. I persist the Employees (because of the relationships the department will be persist also)
I believe this is the right way to do this?!
While providing Annotation @ManyToOne; also provide annotation @JoinColumn
As right now u are only worried about persisting it will work fine. If later you want updates also to work in same way ; you would have to use CascadeType.ALL or CascadeType.MERGE
