java - org.hibernate.MappingException：无法确定类型：java.util.List for Hierarchy Ref Cursor 函数结果

Question

我正在尝试在 DB 中调用一个过程函数，并使用 hibernate 将层次结构答案映射到实体类。我编写的实体假设代表从 ref 游标函数返回的结果结构。该函数的结果有一个属性，它是一个对象列表，并且在该对象内部还有一个属性，它也是另一个对象的列表。在应用程序启动时，我得到了上面标题中所写的 MappingException。我尝试添加注释 @OneToMany 但它不起作用，因为它没有查看数据库中的表。同样，实体代表函数结果，而不是从表中选择。有人知道任何可以防止此异常在应用程序启动中引发的注释吗？

我的实体：

调用过程函数 (rc) 的主要实体：

@NamedNativeQuery(name = "GetDeliveryOptionsRC.runFunction",
        query = "{ ? = call fn_get_delivery_options_rc_dev(:i_account_number,:i_work_order_number,:i_task_id,:i_task_type,:i_content_type_code,:i_sap_operator_code)}", resultClass = GetDeliveryOptionsRC.class,
        hints = {@QueryHint(name = "org.hibernate.callable", value = "true")})
@Entity
@XmlRootElement(name = "GetDeliveryOptionsRC")
public class GetDeliveryOptionsRC implements Serializable {

    @Id
    private Long rownum;

    @Column(name = "ACCOUNT_NUMBER")private Long accountNumber;
    @Column(name = "TASK_TYPE")private Long taskType;
    @Column(name = "CONTENT_TYPE")private String contentType;
    @Column(name = "CONTENT_TYPE_CODE")private Long contentTypeCode;
    @Column(name = "MESSAGE_CODE")private Long messageCode;
    @Column(name = "MESSAGE_ERROR_CODE")private Long messageErrorCode;
    @Column(name = "MESSAGE_ERROR_DESCR")private String messageErrorDescr;
    @Column(name = "DELIVERY_OPTIONS")private List<DeliveryOptionsRC> deliveryOptions;

//getters & setters

}

交付选项实体：

@Entity
@XmlRootElement(name = "DeliveryOptions")
public class DeliveryOptionsRC implements Serializable {

    @Id
    @Column(name = "DELIVERY_TYPE") private String deliveryType;
    @Column(name = "DELIVERY_DESCR") private String deliveryDescr;
    @Column(name = "PRICE") private Double price;
    @Column(name = "EXISTS_FLAG") private String existFlag;
    @Column(name = "IS_VALID") private String isValid;
    @Column(name = "IS_SAP_ORDER") private String isSapOrder;
    @Column(name = "IS_OTHER_ADDRESS") private String isOtherAddress;
    @Column(name = "IS_SCHEDULE_NEEDED") private String isScheduledNeeded;
    @Column(name = "PICKUP_SOURCE") private String pickupSource;
    @OneToMany(targetEntity=ChargeJobs.class, mappedBy="deliveryOptionsRC", fetch=FetchType.EAGER)
    @Column(name = "CHARGE_JOBES") private List<ChargeJobs> chargeJobs;


//getters & setters

}

收费工作实体：

@Entity
@XmlRootElement(name = "ChargeJobs")
public class ChargeJobs implements Serializable {

    @Column(name = "JOB_OFFER_ID") private Long jobOfferId;
    @Id
    @Column(name = "JOB_CODE") private String jobCode;
    @Column(name = "PRICE") private Double price;
    @Column(name = "QUANTITY") private Long quantity;

//getters & setters

}
