JPA HSQL不会从扩展类中获取字段

问题描述

我将以下数据插入到HSQL中：

INSERT INTO Consumer(id,ConsumerId,CREATEDBY,CREATEDAT,FK_Service,ConsumerType) VALUES(300,'adsgvcg-cvvce-hvchwec','sm',CURRENT_TIMESTAMP,1,'INTERNAL');

我有以下从表中读取的类：

Entity(name = "Consumer")
@Table(name = "Consumer")
public class Consumer extends Base {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "ID")
    private long id;

     @Basic(optional = false)
     @Column(name = "ConsumerId", nullable = false)
     private String ConsumerId;

    @Basic(optional = false)
    @Column(name = "ConsumerType", nullable = false)
    private String ConsumerType;

    @Basic//(optional = false)
    @Column(name = "FK_Service", nullable = true)
    private String service;

//Getter Setters etc

和基类看起来像：

public class Base implements Serializable{

    @Basic
    @Column(name = "MODIFIEDBY", nullable = true)
    private String ModifiedBy;

    @Basic
    @Column(name = "MODIFIEDAT", nullable = true)
    private Timestamp ModifiedAt;

    @Basic
    @Column(name = "CREATEDBY", nullable = true)
    private String CreatedBy;

    @Basic
    @Column(name = "CREATEDAT", nullable = true)
    private Timestamp CreatedAt;

//Getter Setters etc

运行代码时，出现以下异常：

2015-07-25 22:21:12,875 ERROR [main] hbm2ddl.SchemaExport.? (?:?) - HHH000388: Unsuccessful: INSERT INTO Consumer(id,ConsumerId,CREATEDBY,CREATEDAT,FK_Service,ConsumerType) VALUES(300,'adsgvcg-cvvce-hvchwec','smenon2',CURRENT_TIMESTAMP,1,'INTERNAL')
2015-07-25 22:21:12,875 ERROR [main] hbm2ddl.SchemaExport.? (?:?) - user lacks privilege or object not found: CREATEDBY

但是，当我将字段从基类移到父（消费者）类时，将不再发生此异常，并且字段也将被填充。
