无法使用OracleDB实例化持久化org.hibernate.persister.entity.JoinedSubclassEntityPersister

我正在尝试将现有的Oracle DB映射到JPA类。但是我在主题行中遇到了提到的错误。无法找出真正的问题。也许我将实体映射错误。

已经尝试过更改类的定义方式。还尝试了在PostgreSQL上正常工作的方法。 


CREATE TABLE "JDTA_ITEM_MULTI_ATTRS" 
   (    "JDTA_ITEM_ID" NUMBER(*,0) NOT NULL ENABLE, 
    "ATTR_DATA_VALUE_ID" NUMBER(*,0) NOT NULL ENABLE, 
    "ATTR_DATA_TYPE_ID" NUMBER(*,0) NOT NULL ENABLE, 
     CONSTRAINT "JDTA_ITEM_MULTI_ATTRS_PK" PRIMARY KEY ("JDTA_ITEM_ID", "ATTR_DATA_VALUE_ID"))

CREATE TABLE "ATTR_DATA_KSATRS" 
   (    "ATTR_DATA_VALUE_ID" NUMBER(*,0) NOT NULL ENABLE, 
    "KSATR_TYPE_ID" NUMBER(*,0) NOT NULL ENABLE, 
     CONSTRAINT "ATTR_DATA_KSATRS_PK" PRIMARY KEY ("ATTR_DATA_VALUE_ID"))

CREATE TABLE "DVMHR4W"."ATTR_DATA_RESOURCES" 
   (    "ATTR_DATA_VALUE_ID" NUMBER(*,0) NOT NULL ENABLE, 
    "ATTR_DATA_RESOURCE_TYPE_ID" NUMBER(*,0) NOT NULL ENABLE, 
    "PART_NUMBER" VARCHAR2(150 BYTE), 
    "SRC" VARCHAR2(300 BYTE), 
     CONSTRAINT "ATTR_DATA_RESOURCES_PK" PRIMARY KEY ("ATTR_DATA_VALUE_ID"))

下面是Java实体类。为了使内容简短，已删除了Getter setter和Constructor。

@Entity
@IdClass(JdtaItemMultiAttrsPk.class)
@Table(name = "JDTA_ITEM_MULTI_ATTRS")
@Inheritance(strategy = InheritanceType.JOINED)
public class JdtaItemMultiAttrs
        implements Serializable
{
    /**
     * generated id
     */
    private static final long  serialVersionUID = 8002L;

    @Id
    @Column(name = "jdta_item_id")
    private int                jdtaItemId;

    @Id
    @Column(name = "attr_data_value_id")
    private int                attributeDataValueId;

    @OneToOne
    @JoinColumn(name = "attr_data_value_id", insertable = false, updatable = false)
    private AttributeDataValue attributeDataValue;

    @Column(name = "attr_data_type_id")
    private int                attributeDataTypeId;
}

public class JdtaItemMultiAttrsPk
        implements Serializable
{
    /**
     * generated id
     */
    private static final long  serialVersionUID = 8002L;

    private int                jdtaItemId;

    private int                attributeDataValueId;
}

@Entity
@Table(name = "ATTR_DATA_RESOURCES")
@PrimaryKeyJoinColumns({@PrimaryKeyJoinColumn(name = "attr_data_value_id")
, @PrimaryKeyJoinColumn(name = "jdta_item_id")})
public class AttrDataResource extends JdtaItemMultiAttrs
        implements Serializable
{
    /**
     * generated id
     */
    private static final long    serialVersionUID = 1600L;

    @Column(name = "attr_data_value_id",insertable = false, updatable = false)
    private int id;

    @Column(name = "attr_data_resource_type_id")
    private int                  attrDataResourceTypeId;

    @OneToOne
    @JoinColumn(name = "attr_data_resource_type_id",insertable = false, updatable = false)
    private AttrDataResourceType attrDataResourceType;

    @OneToOne
    @JoinColumn(name = "attr_data_value_id", insertable = false, updatable = false)
    private AttributeDataValue attributeDataValue;

    @Column(name = "part_number")
    private String               partNumber;

    @Column(name = "src")
    private String               source;
}

@Entity
@Table(name = "ATTR_DATA_KSATRS")
@PrimaryKeyJoinColumns({@PrimaryKeyJoinColumn(name = "attr_data_value_id")
, @PrimaryKeyJoinColumn(name = "jdta_item_id")})
public class AttributeDataKsatr extends JdtaItemMultiAttrs
        implements Serializable
{
    /**
     * generated id
     */
    private static final long  serialVersionUID = 1L;


    @Column(name = "attr_data_value_id",insertable = false, updatable = false)
    private int id;

    @OneToOne
    @JoinColumn(name = "ksatr_type_id")
    private KsatrType          type;

    @OneToOne
    @JoinColumn(name = "attr_data_value_id", insertable = false, updatable = false)
    private AttributeDataValue attributeDataValue;
}

这是我运行此错误

需要在此处查找导致问题的确切原因。我正在使用Spring Boot 2.1.5和Hibernate 5.3.9 / 11，Oracle DB。

当我尝试在PostgreSQL中复制相同的场景时，它起作用了。
