无法使用休眠保存子表数据

阿比吉特

我正在开发Web服务，在这种情况下，存在父子表的情况，如下所示

**Parent Table**

}

现在我正在使用以下REST服务请求来添加带有孩子的主数据

{"description":"Placements","value":"Placements","url":"/Placements","instituteInfoDetails":[{"value":"Test"}]}

保存数据的代码

@Override
    public void addInstituteInfoMaster(com.zertones.model.common.InstituteInfoMatster instituteInfoMatster)
    {
        Session session = sessionFactory.getCurrentSession();
        session.saveOrUpdate(instituteInfoMatster);

    }

但是在保存时却给了我下面的错误

org.hibernate.PropertyValueException: not-null property references a null or transient value : com.zertones.model.common.InstituteInfoDetails.instituteInfotMaster

我按照解决方案进行搜索并添加了级联类型信息，但这并没有帮助。

孔

创建双向Setter方法以将InstituteInfoMatster设置为InstituteInfoDetails

更改类InstituteInfoMatster

public void setInstituteInfoDetails(List<InstituteInfoDetails> instituteInfoDetails)
{
    for(InstituteInfoDetails ins : instituteInfoDetails){
        ins.setComListMaster(this);
    }
    this.instituteInfoDetails = instituteInfoDetails;
}
