Spring jpa本机查询排序添加前缀以按字段名称排序

Question

我的排序有问题。

存储库方法：

@Query(nativeQuery = true,
    value = "SELECT D.ID as dealerId , D.NAME as dealerName, K.ID as kpiId, " +
    "K.NAME as kpiName FROM REGION R, DEALER D, KPI K "
    + "WHERE R.IMPORTER_ID = :importerId "
    + "AND D.REGION_ID = R.ID "
    + "AND K.IMPORTER_ID = :importerId ")

Page<DealersKpiTargets> getDealersKpiTargets(@Param("importerId") Long importerId, Pageable pageable);

可分页对象：

Page request [number: 0, size 20, sort: name: DESC]

休眠日志：

Hibernate: SELECT D.ID as dealerId , D.NAME as dealerName, K.ID as kpiId, K.NAME as kpiName FROM REGION R, DEALER D, KPI K WHERE R.IMPORTER_ID = ? AND D.REGION_ID = R.ID AND K.IMPORTER_ID = ?  order by R.name desc limit ?

我不明白（最后）部分R.name中的前缀来自哪里。order byHibernate

作为参考，我正在使用：

spring-data-jpa 版本 2.0.7.RELEASE

spring-boot-starter-data-jpa 版本 2.0.2.RELEASE

更新

我已经通过将查询从本机查询更改为 jpa 查询来解决这个问题，并且它正在工作。我改变了笛卡尔加入版本。

        @Query("SELECT dealerEntity.id AS dealerId , dealerEntity.name AS dealerName, kpiEntity.id AS kpiId, " +
        "kpiEntity.name AS kpiName FROM KpiEntity kpiEntity "
        + "JOIN RegionEntity regionEntity ON regionEntity.importerEntity = kpiEntity.importerEntity "
        + "JOIN DealerEntity dealerEntity ON dealerEntity.importerEntity = regionEntity.importerEntity "
        + "WHERE kpiEntity.importerEntity = :importerEntity ")
Page<DealersKpiTargets> getDealersKpiTargets(@Param("importerEntity") ImporterEntity importerEntity, Pageable pageable);

它有 Sort 类，您也许可以使用它。此外，它很容易使用。
