однонаправленных многие к одному отношениям с наследованием

Я пытаюсь отобразить многие к одному отношениям между class ED и class TEL в спящем режиме, но я получаю следующее сообщение об ошибке при попытке Run As.. Run on server в затмении:однонаправленных многие к одному отношениям с наследованием

Caused by: org.hibernate.MappingException: Could not determine type for: 
my.package.name.TEL, at table: ed, for columns: 
[org.hibernate.mapping.Column(reference)]

Как могу ли я устранить эту ошибку? Класс ED имеет только одно свойство TEL, но класс TEL используется в качестве свойств во многих других классах, что не имеет смысла делать это двунаправленным отношением. Мне никогда не понадобится искать все объекты ED, связанные с данным TEL. Большинство экземпляров TEL не будут иметь связи с экземплярами ED, но все экземпляры ED будут иметь одно свойство TEL. Я правильно классифицирую отношения? И как изменить код ниже, чтобы устранить эту ошибку? Обратите внимание, что наследование усложняет ситуацию.

Вот TEL.java:

@Entity(name = "tel") 
@Table(name = "tel") 
public class TEL extends ANY { 

    private String value; 

    @Column(name = "value") 
    public String getValue(){return value;} 
    public void setValue(String val){value = val;} 
}

Вот ED.java:

@Entity(name = "ed") 
@Table(name = "ed") 
public class ED extends ANY{ 

    private byte[] data; 
    private String mediaType; 
    private String language; 
    private TEL reference; 

    @Column(name = "data") 
    public byte[] getData(){return data;} 
    public void setData(byte[] d){data = d;} 

    @Column(name = "mediaType") 
    public String getMediaType(){return mediaType;} 
    public void setMediaType(String mt){mediaType = mt;} 

    @Column(name = "language") 
    public String getLanguage(){return language;} 
    public void setLanguage(String lng){language = lng;} 

    @ManyToOne 
    @JoinColumn(name = "hppid") 
    public TEL getReference(){return reference;} 
    public void setReference(TEL ref){reference = ref;} 

}

Вот ANY.java:

@Entity(name = "rim_any") 
@Table(name = "rim_any") 
public class ANY extends BaseEntity{ 

    private CS nullFlavor; 

    public CS getNullFlavor(){return nullFlavor;} 
    public void setNullFlavor(CS nf){nullFlavor = nf;} 

}

Вот BaseEntity.java:

@Entity 
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) 
@DiscriminatorFormula("(CASE WHEN dtype IS NULL THEN 'BaseEntity' ELSE dtype END)") 
@org.hibernate.annotations.DiscriminatorOptions(force=true) 
public abstract class BaseEntity { 

    @Transient 
    private String dtype = this.getClass().getSimpleName(); 

    @Id 
    @GeneratedValue(
     strategy=GenerationType.TABLE, 
     generator="TBL_GEN") 
    @TableGenerator(
     name="TBL_GEN", 
     table="GENERATOR_TABLE", 
     pkColumnName = "mykey", 
     valueColumnName = "hi", 
     pkColumnValue="hppid", 
     allocationSize=20 
    ) 
    protected Long hppid; 

public void setHppid(Long id) {this.hppid = id;} 
public Long getHppid() {return hppid;} 

public void setDtype(String dt){dtype=dt;} 
public String getDtype(){return dtype;} 

public boolean isNew() {return (this.id == null);} 

}

EDIT:

Я пытался @ предложение VladMihalCea о:

@ManyToOne 
@MapsId("hppid") 
public TEL getReference(){return reference;}

в ED.java, но получил ту же ошибку. Затем я попробовал другой его предложение:

@ManyToOne 
@JoinColumn(name = "ref_hppid") 
public TEL getReference(){return reference;}

в ED.Java, но не вносить никаких изменений в TEL.java, или любой другой файл. Это также дает ту же трассировку стека.

Нужно ли внести изменения в TEL.java? Что еще я могу попробовать?

Ed класс наследует hppid столбец из BaseEntity а затем дублировать его с многие к одному ассоциации:

@ManyToOne 
@JoinColumn(name = "hppid") 
public TEL getReference(){return reference;} 
public void setReference(TEL ref){reference = ref;}

Если FK является дополнением к ПК, вы можете просто переименовать его в ref_hppid
```
@JoinColumn(name = "ref_hppid") 
```
Если вы хотите, PK и FK разделить Сэму е колонки, вам нужно использовать @MapsId:
```
@ManyToOne 
@MapsId("hppid") 
public TEL getReference(){return reference;} 
```

Это странно, это не меняет ничего при изменении картографирования. Вы автоматически генерируете схему с помощью hbmddl? –

Изменение должно быть применено к таблице Ed, создавая новый столбец для FK. Я не знаю, что еще может быть неправильно. –

Я понятия не имею. На производственном сервере вы не склонны злоупотреблять наследованием, как в вашем примере. Отображение ставок является самым простым, что отражает схему базы данных. –

однонаправленных многие к одному отношениям с наследованием
