我开发Web服务，以节省子表的数据在此有父子表的情况下，如下无法使用Hibernate
**Parent Table**
@Entity
@Table(name = "INSTITUTE_LIST_MST")
@JsonIgnoreProperties(ignoreUnknown = true)

@OneToMany(fetch = FetchType.EAGER, mappedBy = "instituteInfotMaster", cascade = CascadeType.ALL)
private List<InstituteInfoDetails> instituteInfoDetails = new ArrayList<InstituteInfoDetails>();

private Date createdDate = new Date();
@Column(name = "CREATED_BY")
private String createdBy;
@Column(name = "UPDATED_DT")
@Temporal(TemporalType.TIMESTAMP)

@Column(name = "UPDATED_BY")
private String updatedBy;
@Column(name = "RECORD_STATUS")

public Integer getListId()
{

public void setListId(Integer listId)
{
this.listId = listId;

@Override

现在我使用下面的休息服务请求添加与子女主数据
{"description":"Placements","value":"Placements","url":"/Placements","instituteInfoDetails":[{"value":"Test"}]}
代码来保存数据
@Override
public void addInstituteInfoMaster(com.zertones.model.common.InstituteInfoMatster instituteInfoMatster)
{
Session session = sessionFactory.getCurrentSession();
session.saveOrUpdate(instituteInfoMatster);
}
但同时节省它给了我下面的错误
org.hibernate.PropertyValueException: not-null property references a null or transient value : com.zertones.model.common.InstituteInfoDetails.instituteInfotMaster
我搜索并没有按照我的解决方案添加了级联类型的信息，但它并没有帮助。
