Why do I have to persist both objects if Address is nested in User?

Question

I am trying to better familiarize myself with JPA so I created a very simple project. I have a User Class and an Address class. It appears that I have to persist both even tho

Answer 1

You are using a oneToMany annotation. From my understanding you have to persist the parent class (the USer) when you want to add a child class (Address) to it.

By persisting the User class, you do let know JPA know which row to update.
