你能帮我连接规范和查询,pageable工程完美,但我有一个规范的问题,没有搜索参数添加到哪里。
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);
}
下面是来自日志的sql
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 ?
这是我的演讲稿
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;
}

@Query
以及Specification
不能合并。详见本问答。
