Как контролировать порядок сохранения Spring Data Repository Populator? ⇐ JAVA

[Anonymous]

Я заполняю некоторые исходные данные для проекта и моего класса конфигурации:

import com.fasterxml.jackson.databind.*;
import org.springframework.context.annotation.*;
import org.springframework.core.io.*;
import org.springframework.data.repository.init.*;

@Configuration
public class RepositoryDataInitializer {

protected Resource[] getResources() {
return new Resource[]{
new ClassPathResource("initial-data/permission.json"),
new ClassPathResource("initial-data/permission-set.json"),
new ClassPathResource("initial-data/user.json"),
new ClassPathResource("initial-data/user-group.json"),
};
}

@Bean
public Jackson2RepositoryPopulatorFactoryBean securityRepositoryPopulator() {
var factory = new Jackson2RepositoryPopulatorFactoryBean();
factory.setResources(getResources());
factory.setMapper(new ObjectMapper()
.findAndRegisterModules()
.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
);
return factory;
}

}

Мои данные в формате JSON:

Когда я запускаю проект, я получаю сообщение об ошибке:

Установка атрибута каскада аннотации отношения сущностей JPA к CascadeType с каскадными обновлениями — это не то, что мне нужно, я разработал эти объекты так, чтобы не допускать сохранения каскада.
Я попытался поставить пользователя первым в классе конфигурации, но это не сработало, и я получил ту же ошибку. И есть интересный феномен: если я закомментирую код new ClassPathResource("initial-data/user-group.json") и попытаюсь запустить, проект может завершить работу по инициализации данных, а затем раскомментировать и пытаюсь запустить, получаю сообщение об ошибке.
Я думаю, что если я смогу управлять RepositoryPopulator, чтобы он сохранялся в порядке Permission, PermissionSet, User, UserGroup, Я могу решить эту проблему или мои мысли в неправильном направлении?
Спасибо большое за любую информацию!
