我在休眠中使用子选择来返回一个包含所有相关表上的 id 而不是对象的对象。
这是我定义的 dto
@Entity
@Subselect("select di.id as id, user.id as userId, client.id as clientId, controller.id as controllerId,"
+ "supplier.id as supplierId, grade.id as gradeId, packing.id as packingId, warehouse.id as warehouseId,"
+ "qualityController.id as qualityControllerId,"
+ "companyMasterByPledger.id as pledgerId,"
+ "di.refNumber as refNumber,"
+ "di.clientRef as clientRef,"
+ "di.date as date,"
+ "di.supplierRef as supplierRef,"
+ "di.tons as tons,"
+ "di.kgPerBag as kgPerBag,"
+ "di.noOfBags as noOfBags,"
+ "di.deliveryDate as deliveryDate,"
+ "di.fromTime as fromTime,"
+ "di.toTime as toTime,"

@Synchronize({"DeliveryInstruction"})
public class DeliveryView implements Serializable{

@Id
public Integer getId() {
return id;
}
// ... others getter and setter
}
在 DAO 类中，该方法如下所示
public DeliveryView getDiById(int id) {
return (DeliveryView) getHibernateTemplate().get(DeliveryView.class, id);
}
但是，当我使用上述方法时，它返回 null。
当我运行该方法时，打印到控制台的脚本是
select deliveryvi0_.id as id36_0_, deliveryvi0_.clientId as clientId36_0_, deliveryvi0_.clientRef as clientRef36_0_, deliveryvi0_.controllerId as controll4_36_0_, deliveryvi0_.date as date36_0_, deliveryvi0_.deliveryDate as delivery6_36_0_, deliveryvi0_.fromTime as fromTime36_0_, deliveryvi0_.gradeId as gradeId36_0_, deliveryvi0_.kgPerBag as kgPerBag36_0_, deliveryvi0_.log as log36_0_, deliveryvi0_.markingOnBags as marking11_36_0_, deliveryvi0_.noOfBags as noOfBags36_0_, deliveryvi0_.originId as originId36_0_, deliveryvi0_.packingId as packingId36_0_, deliveryvi0_.pledgerId as pledgerId36_0_, deliveryvi0_.qualityControllerId as quality16_36_0_, deliveryvi0_.qualityId as qualityId36_0_, deliveryvi0_.refNumber as refNumber36_0_, deliveryvi0_.remark as remark36_0_, deliveryvi0_.status as status36_0_, deliveryvi0_.supplierId as supplierId36_0_, deliveryvi0_.supplierRef as supplie22_36_0_, deliveryvi0_.toTime as toTime36_0_, deliveryvi0_.tons as tons36_0_, deliveryvi0_.userId as userId36_0_, deliveryvi0_.warehouseId as warehou26_36_0_ from DeliveryView deliveryvi0_ where deliveryvi0_.id=?
它从 DeliveryView 表中获取不存在的数据，我想要的是从 DeliveryInstruction 表中获取数据。请帮我改正，谢谢
P / s：我正在使用spring和hibernate，我这样做是为了与jackson一起工作以防止它加载大量冗余信息（我使用了jackson hibernate模块，但它返回了很多不必要的信息，而不仅仅是id） . 所以如果你有更好的想法，请告诉我，谢谢。
- 更新：我看到@subselect 上的脚本没有运行，当我调用“get(DeliveryView.class, id)”方法时，它执行默认脚本“select * from deliveryView”。
更新：这是我检查过的本机脚本
