Hibernate Add Model with OneToMany

I have got an PersonModel which has an address.

Looks like that:

public class PersonModel {
@ManyToOne(fetch = FetchType.LAZY)
private AddressModel address;

public class AddressModel {
private String street;
private String city;

@OneToMany(fetch = FetchType.LAZY, mappedBy = "address", cascade = CascadeType.ALL)
private Set<PersonModel> persons;

Now, when I get this JSON from my Client:

"person": {
"address": {
"street": "Examplestreet",
"city": "Examplevillage"

And try to save it like that:


Hibernate will always throw a TransientPropertyValueException.

object references an unsaved transient instance - save the transient instance before flushing

Do I really have to save every single DB-Entry related to person first or is there another way?

Try adding CascadeType.ALL at the @ManyToOne annotation.

This achieves that your Person gets saved automatically if you save your Address
