Hibernate发生错误，我有两个与Oracle模式关联的模型类Cart和prodmast。购物车与prodmast具有OneToMany关系，prodmast与购物车具有多对一的关系。Hibernate尝试在Oracle中的外键中插入null
但是当我尝试插入ecomcart，我得到 “ORA-01400：无法将NULL插入...”
堆栈跟踪
Hibernate: insert into ecom_cart (bundle_item_slno, discount, discount_perc, free_qty, price, qty, vat_perc, company_id, item_slno, session_id) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

提供'EcomProdmastId'的代码（没有它）（使用简单的id）id对我有效 –
@DmitrySenkovich增加了EcomProdmastId和EcomCartId类，这些模型类是由hibernate reverse eng方法生成的。 – sreeroop
