你好，我正在試圖從MySql數據庫使用spring jpa拉記錄。春季數據jpa加入具有多個參數的查詢
實體1
@Entity @Table(name = "sku_warehouse") @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) @Document(indexName = "skuwarehouse") public class SkuWarehouse extends AbstractAuditingEntity implements Serializable {

實體2：拉記錄
@Query("select sw from SkuWarehouse sw left join fetch Warehouse w where sw.warehouse = w.warehouseId AND w.warehouseId=:warehouseId AND sw.skuMaster=:skuMasterId")
SkuWarehouse findOneWithEagerRelationships(@Param("warehouseId") String warehouseId, @Param("skuMasterId") Long skuMasterId);

select * from sku_warehouse sw
join warehouse w on (sw.warehouse_id = w.id)
where w.warehouse_id='024'
and sw.sku_master_id='1072'

什麼是錯誤的JPA查詢？我甚至嘗試傳遞SkuMaster對象而不是Long，但後來我得到MySql查詢異常。
類是私有的，沒有消氣。 –
Id是實體類中的字段，定義爲 '@Id @GeneratedValue（strategy = GenerationType.IDENTITY） private Long id;' –
我的jpa查詢是否正確？ –
