Spring boot 使用JPA@onetomany和@manytoone注释将数据插入到三个表中

我试图通过使用JPA存储库和spring boot应用程序将数据插入三个不同的表中。为此，我在这三个类中使用了@onetomany和@manytoone注释：

家庭

所有者详细信息

家庭成员

但是当我尝试插入时，我得到了以下错误

我还为每个实体类创建了存储库类。有人能帮我解决这个错误吗。提前感谢。

[JPA Examplem][1对多和多对1关系][]

您如何为“hid”创造价值？错误显示：错误：“hid”列中的null值违反了not null约束为此，我在OwnerDetails类public Long getHid（）{return househouse.getHid（）；}中创建了一个get方法，它是返回HOusehouse hid值，但不起作用。“hid”列是自动递增值吗？get方法不会为“hid”生成新值。您需要生成“hid”或让数据库处理它。从我的角度看，它将如何生成？实际上，在Househouse类中，我使用了@GeneratedValue（strategy=GenerationType.IDENTITY），该类工作正常，但在OwnerDetails类中，我使用了@ManyToOne注释，其中的Househouse对象没有得到值，因此给出了错误。你知道我该怎么做吗。当我从@JoinColumn注释中删除nullable=false时，数据会插入到所有三个表中，但在ownerdetails和householdmembers表的外键列中设置的值为null。请用文字解释答案。当链接过期时，链接只回答失去意义的问题。
