What does relationship owner means in bidirectional relationship?

Question

I have a simple model with a Question and Choice object.

• ONE Question has MANY CHOICE(S).
• MANY Choice has ONE Question

Answer 1

It is also important to remember that without mappedBy you will run into an issue of circular dependencies. This happens when there is no owner in a bidirectional relationship.

In a circular dependency you will (explicitly) set both sides of the entities before saving

thisObj.set(thatObj);
thatObj.set(thisObj);
