How to force hibernate not update all entities with same id?

Question

When I save the newAddress using JpaRepository<Address, AddressID> save method it updates all references of the method scope, including oldRegistration .

Since I wanna execute other actions with the oldRegistration data after the newAddress is saved It is giving me an unexpected behavior.

    Registration registerAddress(String cpf, MultipartFile file) throws IOException {

        Registration oldRegistration = registrationService.findById(new CPF(cpf)).orElseThrow(RegistrationNotFound::new);
        Address oldAddress = addressService.findById(oldRegistration.getAddressId()).orElseThrow(AddressNotFoundException::new);

        StorageFile newStorageFile = storageFileService.saveImage(file.getOriginalFilename(), file.getInputStream(), file.getSize());

        Address newAddress = oldAddress.setStorageFile(newStorageFile.getId());
        Registration newRegistration = oldRegistration.registerAddressFile(newAddress.getId());

        addressService.save(newAddress);
        Registration savedRegistration = registrationService.save(newRegistration);

        storageFileService.findById(oldAddress.getStorageFileId()).ifPresent(storageFile -> {
            storageFileService.delete(storageFile);
            storageFileService.removeFromStorageAsync(storageFile);
        });

        return savedRegistration;
    }

I'm expecting the oldAddress keep all its data.

After addressService.save(newAddress); all data from oldAddress is setted as the same of the newAddress .

How to tell Spring does not update every reference that has the same id?

Answer 1

oldAddress is a managed entity having the same id as newAddress . You need to EntityManager.detach() it from the context before saving the newAddress .
