Java 未在子表中插入外键

我试图插入组织及其人员详细信息（一对多双向关系）

但是，这里数据被插入到组织及其人员详细信息中，但是外键（

orgid

）没有被插入到

orgperson

表中

请尝试下面的代码，您没有将组织设置为orgperson实体

    Session session = sf.openSession();
    session.beginTransaction();

    Organization org=new Organization();
    org.setOrgname("AZZ");
    Set<Orgperson> orgset=new HashSet<Orgperson>();

    Orgperson orgperson1=new Orgperson();
    Orgperson orgperson2=new Orgperson();

    orgperson1.setPersonname("ravi");
    orgperson2.setPersonname("rams");
    orgperson1.setOrganization(org);
    orgperson2.setOrganization(org);
    orgset.add(orgperson1);
    orgset.add(orgperson2);
    org.setOrgpersons(orgset);
    session.save(org);

    session.close();

@Column（unique=true，nullable=false）私有int-orgid

为该列指定一个类似于

@Column（name='orgid'，unique=true，nullable=false）private int-orgid的名称@JoinColumn（name=“orgid”）

和

@ManyToOne

移动到get方法

公共组织getOrganization（）

我已经像您所说的那样进行了更改，但仍然没有插入到orgperson表中。
