如何在Hibernate中將一個屬性映射到多個屬性？

Question

如何在hibernate中將一個屬性映射到2個屬性？
例子：

@Entity 
@Table(name = "Author") 
public class ModelAuthor extends Model { 

    @ManyToMany(mappedBy = "authorList", 
       fetch = FetchType.LAZY) 
    private Set<ModelConceptualBook> conceptualBookList; 
} 


@Entity 
@Table(name = "ConceptualBook") 
public class ModelConceptualBook extends Model { 

    @ManyToMany(fetch = FetchType.LAZY) 
    @JoinTable(name = "ConceptualBook_Author", 
       joinColumns = {@JoinColumn(name = "conceptualBookId")}, 
       inverseJoinColumns = {@JoinColumn(name = "authorId")}) 
    private Set<ModelAuthor> authorList; 

    private Set<ModelAuthor> translatorList; 
} 

現在我想有anaother表ConceptualBook_Author映射translatorList從ModelConceptualBook到ModelAuthor像authorListconceptualBookList。
如何實現此功能？
非常感謝您的幫助;）

Answer 1

通過簡單地使用其他表 - 例如ConceptualBook_Translator。

@ManyToMany(fetch = FetchType.LAZY) 
@JoinTable(name = "ConceptualBook_Translator", 
      joinColumns = {@JoinColumn(name = "conceptualBookId")}, 
      inverseJoinColumns = {@JoinColumn(name = "authorId")}) 
private Set<ModelAuthor> translatorList; 

而在另一邊的關係如下：

@ManyToMany(mappedBy = "translatorList", 
       fetch = FetchType.LAZY) 
    private Set<ModelConceptualBook> booksTranslated;
