Hibernate发生错误，我有两个名为Cart的模型类和与Oracle模式相关的prodmast。购物车与prodmast有着OneToMany关系，而prodmast与购物车有着多对一的关系。
但是当我尝试插入ecomcart时，我得到＆＃34; ORA-01400：无法将NULL插入...＆＃34;
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 (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

答案 0 :(得分：0)
我设法让它取代
@JoinColumns({
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", nullable = false, insertable = false, updatable = false),
@JoinColumn(name = "PART_NO", referencedColumnName = "PART_NO", nullable = false, insertable = false, updatable = false),
@JoinColumn(name = "UNIT", referencedColumnName = "UNIT", nullable = false, insertable = false, updatable = false)
})
与
@PrimaryKeyJoinColumns({
@PrimaryKeyJoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID"),
@PrimaryKeyJoinColumn(name = "PART_NO", referencedColumnName = "PART_NO"),
@PrimaryKeyJoinColumn(name = "UNIT", referencedColumnName = "UNIT")
})
问题是您使用相同的列名作为复合主键的一部分以及外键。仔细查看EcomCart类中的这些映射：
@AttributeOverride(name = "companyId", column = @Column(name = "COMPANY_ID", nullable = false, length = 2))
以及以下内容：
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", nullable = false, insertable = false, updatable = false)
在这种情况下，您应该使用@PrimaryKeyJoinColumns。
