java - hibernate 错误 : Validation failed for query for method public abstract java. util.List

Question

在这里，我想从特定用户的订单表中检索所有订单，按 DESC 中的 orderDate 排序，以及 OrderStatus 为 True 的订单位于列表顶部......

但是我在执行代码时遇到错误， Hibernate 错误:公共(public)抽象 java.util.List 方法查询验证失败

用户

@Entity
@Getter
@Setter
@Table(name = "Users")
public class User {

    @Id
    @Column(name = "user_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "user",cascade = CascadeType.ALL)
    private List<Orders> orders;

 
}

订单

@Entity
@Getter
@Setter
@Table(name="Orders")
public class Orders {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "order_id")
    private int id;

    private Date orderDate;

    @OneToOne(cascade = CascadeType.ALL,fetch = FetchType.EAGER)
    @JoinColumn(name = "order_id")
    @MapsId
    private OrderStatus orderStatus;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "user_id")
    @JsonIgnore
    private User user;
}

订单状态

@Entity
@Table(name="Order_Status")
@Getter
@Setter
public class OrderStatus {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "order_id")
    private int id;
    private boolean delivered;
    private boolean shipped;
}

存储库

public interface OrdersRepository extends JpaRepository<Orders,Integer> {

    @Query("select o from Orders o where o.user.id=:userid ORDER BY (o.orderStatus.shipped=true), o.orderDate DESC")
    List<Orders> getALlOrders(@Param("userid") int userid);

}

Answer 1

为什么要在 Order by 子句中传递列值？

根据日志，问题仅出在 o.orderStatus.shipped=true 上。

通过从查询中删除 =true 来更改查询，或者通过查询从订单中删除已发货，因为按 shipped 列排序没有任何意义。
