java是由：org引起的。冬眠QueryException:无法解析属性：

Question

我犯这个错误的原因很奇怪。我将按时间顺序解释错误，以便于理解

这是我的JPA查询，在我添加po之前它一直工作得很好。客户识别号

@Query("SELECT NEW com.htd.domain.ShopOrder(po.id, po.po_number, "
            + "po.due_date, po.customer_id, po_part.id,po_part.part_quantity, "
            + "part.id, part.part_number, part.part_description, "
            + "part.plasma_hrs_per_part, part.grind_hrs_per_part, "
            + "part.mill_hrs_per_part, part.brakepress_hrs_per_part) "
            + "FROM Po po "
            + "JOIN po.partList po_part "
            + "JOIN po_part.part part "
            + "where po.id = ?1")
    List<ShopOrder> getShopOrder(Long id);

ShopOrder构造函数

 public ShopOrder(long po_id, String po_number, LocalDate po_due_date, BigInteger customer_id,
                     long po_part_id, int part_quantity, long part_id,
                     String part_number, String part_decription, BigDecimal plasma_hrs,
                     BigDecimal grind_hours, BigDecimal mill_hrs,
                     BigDecimal breakpress_hrs) {

        this.po_id = po_id;
        this.po_number = po_number;
        this.po_due_date = po_due_date;
        this.po_part_id = po_part_id;
        this.part_quantity = part_quantity;
        this.part_id = part_id;
        this.part_number = part_number;
        this.part_decription = part_decription;
        this.plasma_hrs = plasma_hrs;
        this.grind_hours = grind_hours;
        this.mill_hrs = mill_hrs;
        this.breakpress_hrs = breakpress_hrs;
        this.customer_id = customer_id;

    }

我很困惑为什么我调用的表中的一列不被识别。我已经玩了一段时间了，但感觉像是在追我的尾巴

----更新-------

 public ShopOrder(long po_id, String po_number, LocalDate po_due_date, long customer_id,
                     long po_part_id, int part_quantity, long part_id,
                     String part_number, String part_decription, BigDecimal plasma_hrs,
                     BigDecimal grind_hours, BigDecimal mill_hrs,
                     BigDecimal breakpress_hrs) {

我注意到表中的其他BigInt变量在构造函数中很长。因此，我将customer_id改为Long，但仍然得到相同的错误

实体（Po类）中没有customer_id属性。 你应该有这样的东西：

@Entity
public class Po {
    // ...

    @Basic
    long customer_id;

    // ...
}
