Hibernate以错误的顺序持久保存我的OneToOne实体

我正在使用Hibernate 4.3.11并尝试将一对一关系的实体持久化到另一个实体，但Hibernate似乎试图以错误的顺序执行持久性，从而导致ConstraintViolationException .

这是我的实体：

@Entity
@Table(name = "B2B_ORDER")
public class Order implements java.io.Serializable
{

    @Id
    @Column(name = "ORDER_NUMBER", unique = true, nullable = false, length = 32)
    private String              orderNumber;

    @OneToOne(optional = false, cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "order")
    private OrderCustomer       orderCustomer;
...
}

@Entity
@Table(name = "B2B_ORDER_CUSTOMER")
public class OrderCustomer implements java.io.Serializable
{

    @Id
    @Column(name = "ORDER_NUMBER")
    private String            orderNumber;

    @OneToOne(optional = false)
    @JoinColumn(name = "ORDER_NUMBER", referencedColumnName =  "ORDER_NUMBER")
    private Order             order;
...
}

我要做的就是使用OrderCustomer创建一个Order并保留Order，它也应该创建OrderCustomer记录：

Order order = new Order();
order.setOrderNumber(orderNumber);
...
OrderCustomer orderCustomer = new OrderCustomer();
orderCustomer.setOrder(order);
orderCustomer.setOrderNumber(order.getOrderNumber());
order.setOrderCustomer(orderCustomer);
...
order = orderRepository.save(order);

请注意，orderRepository是一个Spring存储库对象，所有save方法都是调用entityManager.persist（entity） . 当我运行此代码时，由于外键，我在数据库中遇到了完整性约束违规：

显然，Hibernate试图在Order之前坚持OrderCustomer . 这是应该保持的相反顺序 . 如果考虑OneToMany级联关系，则单个实体将始终在集合之前保留（因此满足外键） . 为什么这对一对一不起作用？

谢谢 .
