Я хочу изменить сравнение root -объекта в QueryDSL: допустим, у меня есть страна-субъект, и я хочу изменить сравнение этих стран-субъектов друг с другом. По этой причине я настроил привязки в Querydsl следующим образом:
@Repository
public interface CountryRepository extends JpaRepository<Country, Integer>,
QuerydslPredicateExecutor<Country>,
QuerydslBinderCustomizer<QCountry> {
@Override
default void customize(QuerydslBindings querydslBindings, QCountry root) {
querydslBindings.bind(root).first((QCountry path, Country value) -> {
if (value.getTranslation().getId().equals("de") && !value.getTranslation().getDenomination().isEmpty()) {
return path.id.eq(value.getId());
} else {
return path.countryDetail.id.eq(value.getCountryDetail().getId()).and(path.translation.languageid.eq("en"));
}
});
}
}
Проблема в том, что QueryDSl говорит, что у него нет root пути:
java.lang.IllegalStateException: Couldn't find root path on path country!

Я что-то пропустил?
