Answer 1

If the server error looks like this: object references an unsaved transient instance - save the transient instance before flushing

You should have something like this in the Address class:

@OneToMany(
mappedBy = "provider", 
orphanRemoval = true,
cascade = CascadeType.ALL)
private Set<Address> addresses = new HashSet<>();

If it's not that error, you could edit your post and add a screenshot.

Answer 2

I think while saving provider you are not getting address that's why it's showing EntityNotFoundException.

You can try with fetch = FetchType.EAGER in your address mapping so it will fetch addresses immediately.
