ORA-00904: 映射问题导致标识符无效

Question

我有一个问题，该问题的名称如下所示。

java.sql.SQLSyntaxErrorException: ORA-00904: "DETAILORDE1_"."BOOK": invalid identifier

意思是不映射Book和DetailOrder class.

我搜索了很多资源来解决这个问题。我尝试了他们的很多选择，但没有任何改变。 pk.book 价值无法从书中感知 class.

我该如何解决？

下面是代码。

图书

@Entity
@Table(name="BOOK",catalog = "JSPPROJECTDATABASE")
public class Book implements Serializable{
...
@OneToMany(mappedBy = "pk.book", cascade=CascadeType.ALL)
private Set<DetailOrder> detailOrders = new HashSet<DetailOrder>();

详细订单

@Entity
@Table(name = "DETAIL_ORDER", catalog = "JSPPROJECTDATABASE")
@AssociationOverrides({
        @AssociationOverride(name = "pk.orders", 
            joinColumns = @JoinColumn(name = "ORDER_ID")),
        @AssociationOverride(name = "pk.book", 
            joinColumns = @JoinColumn(name = "BOOK_ID")) })
public class DetailOrder implements Serializable{
...
@EmbeddedId
    public DetailOrderId getPk() {
        return pk;
    }

    public void setPk(DetailOrderId pk) {
        this.pk = pk;
    }

    @Transient
    public Book getBook() {
        return getPk().getBook();
    }

    public void setBook(Book book) {
        getPk().setBook(book);
    }

    @Transient
    public Orders getOrders() {
        return getPk().getOrders();
    }

    public void setOrders(Orders orders) {
        getPk().setOrders(orders);
    }

DetailOrderId

@Embeddable
public class DetailOrderId implements Serializable{

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name = "BOOK_ID")
    private Book book;

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name = "ORDER_ID")
    private Orders orders;

    public Book getBook() {
        return book;
    }
    public void setBook(Book book) {
        this.book = book;
    }
    public Orders getOrders() {
        return orders;
    }
    public void setOrders(Orders orders) {
        this.orders = orders;
    }
