hibernate.QueryException:无法解析的属性：InventoryItems:com.example.demo.model.PurchaseOrder

获取采购订单列表时出现查询异常。 hibernate.QueryException:无法解析的属性：InventoryItems:com.example.demo.model.PurchaseOrder

实体存货

@Entity
@Table(name = "inventory")
public class Inventory {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
private String name;
private String unit_of_measurement;
private float unit_cost;
private int opening_balance;
private float dim_length;
private float dim_breadth;
private float dim_height;
}

实体购买

enter code here
@Entity
@Table(name="purchase_order")
public class PurchaseOrder {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long purchase_order_number;
private String vendor_name;
private Date purchase_order_date;
private float tax;

@Column(name = "total_cost", columnDefinition ="real default 0")
private double total_cost;
@Column(name ="net_cost", columnDefinition = " real default 0")
private double net_cost;


@OneToMany(mappedBy = "purchaseOrder",orphanRemoval = 
           true,fetch=FetchType.LAZY   )
private List<InventoryItems> inventoryItems;
}

我正在尝试编写此查询，但它引发了一个异常

@Query("select po from PurchaseOrder as po  join po.InventoryItems as 
i where i.id=?1 ")
List<PurchaseOrder> findPurchaseOrderByItem(long id);

@Query（“从PurchaseOrder中选择po作为po加入po.InventoryItems作为
i其中i.id=？1”）
列出findPurchaseOrderByItem（长id）；

在采购实体中，您已声明字段inventoryitems，小写字母为“i” 专用清单清单项目

而在编写查询时，您使用了po.InventoryItems

---

尝试改用po.inventoryItems。

乐意帮忙：）乐意帮忙：）

@Query("select po from PurchaseOrder as po  join po.InventoryItems as 
i where i.id=?1 ")
List<PurchaseOrder> findPurchaseOrderByItem(long id);
