Mapping this relationship with 2 entities using the same entity - mysql

Question

I´m making the model classes using Hibernate, but I don´t know what to do with this kind of relationship.
I have three tables.
Adrress, employee and person.
One emplooye can have one adrress and one person can have one addrress.
I don´t know how map.
Because I thought to use embedded annotattion but doesn´t work.
First is to map my class, I need to put this two entities in address class?
What kind of annotattion i need to use?
I use a superclass with id property and every class extends.
I´m using mysql

my database have foreign key constraint, I´m using mysql

Answer 1

I found my problem, I was saving only one object, because I thought if I use the save for the object who contains other it will save, but I need before save the address and later the person.
So this way everthing worked.
