Spring Data @Query + Spesifikasi

Question

Dapatkah Anda membantu saya menghubungkan Spesifikasi dan Kueri, Pageable berfungsi dengan sempurna tetapi saya memiliki masalah dengan Spesifikasi, tidak ada parameter pencarian yang ditambahkan ke mana.

public interface RakebackRepository extends JpaRepository<Rakeback, Long>,JpaSpecificationExecutor<Rakeback> {

    @Override    
    @Query(value = "SELECT new domain.model.poker.rakeback.Rakeback(ppr.playerId, SUM(ppr.rakeSum), SUM(ppr.fullRakeBackSum), max(ppra.rakeBackBalance), max(ppra.rakebackRank)) FROM Rakeback as ppr LEFT JOIN ppr.Rakeback as ppra on ppra.status = 'active' LEFT JOIN ppra.rakebackRank as rbb on ppra.rakeBackRankId = rbb.id GROUP BY ppr.playerId ")   
    Page<Rakeback> findAll(Specification<Rakeback> specification, Pageable pageable);
    
    }

Ini SQL dari log

select pokerplaye0_.player_id as col_0_0_,  sum(pokerplaye0_.rake_sum) as col_1_0_,  sum(pokerplaye0_.full_rake_back_sum) as col_2_0_,  max(pokerplaye1_.rake_back_balance) as col_3_0_,  max(pokerplaye1_.rake_back_rank_id) as col_4_0_ 
from rakeback.players_rakebacks pokerplaye0_  
left outer join rakeback.players_rakebacks pokerplaye1_ on pokerplaye0_.player_id=pokerplaye1_.player_id and (pokerplaye1_.status='active')  
left outer join rakeback.rakeback_settings pokerrakeb2_ on pokerplaye1_.rake_back_rank_id=pokerrakeb2_.id and (pokerplaye1_.rake_back_rank_id=pokerrakeb2_.id) 
group by pokerplaye0_.player_id 
order by pokerplaye0_.player_id desc limit ?

Ini Speec saya

public class RakebackListSpec {

private final OperatorService operatorService;
private final PlayerService playerService;



public static Specification<Rakeback> byPlayerId(Long id) {
    return (root, query, criteriaBuilder) ->
            criteriaBuilder.equal(root.get("playerId"), id);
}

public static Specification<Rakeback> byOperator(Integer operatorId) {
    return (root, query, criteriaBuilder) ->
            criteriaBuilder.equal(root.get("operatorId"), operatorId);
}

public Specification<Rakeback> getSpec(RakebackListRequestDto request) {

    Specification<Rakeback> spec = Specification.where(byOperator(operatorService.getOperator().getId()));

    if(request.getOpPlayerId() != null){
        CorePlayer player = playerService.getPlayerByOpPlayerId(request.getOpPlayerId());
        spec = spec.and(byPlayerId(player.getId()));
    }


    return spec;
}

@Querydan Specificationtidak bisa digabungkan. Lihat Pertanyaan / Jawaban SO ini untuk detailnya.
