please can you help me. and thank you in advance
Solution
Okay, please have a look at the OneToMany Springboot annotation, it gives you a basic idea of how you should set up your one-to-many/many-to-one relationship.
Also, the typeDeVente entity needs a @OneToMany(mappedBy="typeDeVente") annotation as well.
