JPA - во время синхронизации был обнаружен новый объект через связь, которая не была отмечена каскадом PERSIST.

Question

Я использую JPA, и у меня возникли проблемы с сохранением объекта.

Программа ERD

Программа представляет собой простое веб-приложение корзины покупок: покупатель может разместить много заказов, которые могут содержать много продуктов.

Таблица клиентов -> таблица упорядоченных (заказов) -> таблица order_product -> таблица продуктов

Моя проблема в том, что я пытаюсь сохранить объект заказа и не удалось, в заголовке сообщения появляется ошибка.

Ниже вы можете увидеть некоторые результаты, показывающие состояние объекта до попытки сохранения.

Info: entity.Orderly[ id=null ] Info: Date Placed: Tue May 26 00:00:00 AEST 2020 Info: Status: PROCESSING Info: Grand Total: 782.00 Info: Customer ID: entity.Customer[ id=1 ] Info: Order Products List: [entity.OrderProduct[ orderProductPK=entity.OrderProductPK[ orderId=null, productId=2 ] ]]

Вот соответствующие биты моей сущности Orderly

public class Orderly implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
...
    @JoinColumn(name = "CUSTOMER_ID", referencedColumnName = "ID")
    @ManyToOne(optional = false)
    private Customer customerId;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "orderly")
    private Collection<OrderProduct> orderProductCollection;

Вот подходящие биты моей сущности OrderProduct

public class OrderProduct implements Serializable {
    private static final long serialVersionUID = 1L;
    @EmbeddedId
    protected OrderProductPK orderProductPK;
...
    @JoinColumn(name = "CUSTOMER_ID", referencedColumnName = "ID")
    @ManyToOne(optional = false)
    private Customer customerId;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "orderly")
    private Collection<OrderProduct> orderProductCollection;

Добавить метод заказа в моем OrderFacade:

Orderly o = orderDTO2DAO(order);

// set up customer on order
o.setCustomerId(customerDTO2DAO(customerFacade.getRecordFromUsername(username)));

// set up products contained within order
o.setOrderProductCollection(getOrderProducts(order, products));

if (o == null)
{
    return false;
}

create(o);

return true;

Настройка коллекции OrderProducts в моей сущности Order

ArrayList<OrderProduct> opList = new ArrayList<OrderProduct>();

        for(ProductDTO p : products)
        {
            OrderProductPK opPK = new OrderProductPK(p.getId());
            OrderProduct op = new OrderProduct(opPK, p.getQuantity(), getLineTotal(p));
            op.setOrderly(orderDTO2DAO(order));
            op.setProduct(productDTO2DAO(p));
            opList.add(op);
        }

return opList;

В методе создания я просто вызываю persist (order).

У меня есть подозрение, что это из-за таблицы Order_Product слабый d использует order_id и product_id в качестве составного ключа.

Вот журнал сервера Glassfi sh с некоторыми данными stacktrace
