ORA-00904："BOOKORDERS"： Hibernate中的无效标识符

Question

我在将订单信息插入oracle数据库时遇到了问题。当我在JUnit类中调用createOrder funtion时，它会抛出如下所示的错误。

Hibernate: select ORDERS_SEQ.nextval from dual
Hibernate: insert into BOOKORDERS (CUSTOMER_ID, ORDER_DATE, ORDER_STATUS, 
ORDER_TOTAL, PAYMENT_METHOD, RECIPIENT_NAME, RECIPIENT_PHONE, 
SHIPPING_ADDRESS, ORDER_ID) values (?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into DETAILORDER (quantity, subTotal, book, bookorders) 
values (?, ?, ?, ?)

logExceptions
WARN: SQL Error: 904, SQLState: 42000
May 22, 2019 12:26:18 PM org.hibernate.engine.jdbc.spi.SqlExceptionHelper 
logExceptions
ERROR: ORA-00904: "BOOKORDERS": invalid identifier

我该怎么修？

我可以在实体包中与其相关类共享相关代码订单类。

测试插入代码

@Test

        System.out.println("testCreateOrder");
        BookOrders bookorders = new BookOrders();

        Customer customer = new Customer();
        customer.setId(42);

        bookorders.setCustomer(customer);
        bookorders.setRecipentName("Recipent Name");
        bookorders.setRecipentPhone("123456789");
        bookorders.setShippingAddress("Address");

        Set<DetailOrder> orderDetails = new HashSet<DetailOrder>();
        DetailOrder detailOrder = new DetailOrder();

        Book book = new Book(24);
        detailOrder.setBook(book);
        detailOrder.setQuantity(1);
        detailOrder.setSubTotal(33.99f);
        detailOrder.setOrders(bookorders);

        orderDetails.add(detailOrder);

        bookorders.setOrderDetails(orderDetails);

        BookOrders savedOrders = ordersDAO.create(bookorders);

        assertNotNull(savedOrders);
        //assertTrue(savedOrders.getId() > 0);


    }

我解决了这个问题。

DetailOrder类

public class DetailOrder implements Serializable{

    @EmbeddedId
    @AttributeOverrides({ @AttributeOverride(name = "ORDER_ID", column = @Column(name = "ORDER_ID", nullable = false)),
        @AttributeOverride(name = "BOOK_ID", column = @Column(name = "BOOK_ID", nullable = false))})
    private DetailOrderId pk = new DetailOrderId();

    @ManyToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL)
    @JoinColumn(name = "BOOK_ID", insertable = false, updatable = false, nullable = false)
    private Book book;

    @ManyToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL)
    @JoinColumn(name = "ORDER_ID", insertable = false, updatable = false, nullable = false)
    private BookOrders bookorders;  }
