Возникла проблема при создании OnetoMany с JoinColumn в Hibernate при работе с CASCADE

Я пытаюсь сохранить данные в WorkItem Table, используя RestController с JSON ниже: 

{
    "wrkitmid": "123",
    "linkingApplRef": [
        {
            "linkingApplRefid": "1",
            "documentPage": [
                {
                    "docpageid": 123
                }
            ]
        }
    ]
}

Но я получаю эту ошибку

Невозможно найти com.example.demo.LinkingApplRef с идентификатором 1

Редактировать:

В соответствии с предложением Клавдия я пытался с linkingApplRef в JSON, который присутствовал в БД, и он успешно выполнен,Но когда я применил CASCADE в WorkItem Entity: 

@OneToMany(CASCADE) 
@JoinColumn(name = "WRK_ITM_ID") 
private List<LinkingApplRef> linkingApplRef;

& CASCADE в LinkingApplRef 

@OneToMany(CASCADE) 
@JoinColumn(name = "LINK_APP_REF_ID") 
private List<DocumentPage> documentPage;

с тем же JSON (со связыванием ApplRef с ID 1), он работал без сбоев

Restcontroller выглядит следующим образом: 

@RequestMapping(value="/saveWorkItem", method=RequestMethod.POST,consumes=MediaType.APPLICATION_JSON_VALUE)
    public String savebiWorkItem (@RequestBody WorkItem w1) {
    System.out.println(w1);
    for (LinkingApplRef linkingApplRef : w1.getLinkingApplRef()) {
       linkingApplRef.setWorkItem(w1.getWrkitmid());
          for ( DocumentPage documentPage : linkingApplRef.getDocumentPage()) {
    documentPage.setLinkingApplRefid(linkingApplRef.getLinkingApplRefid());
            documentPage.setWorkItem(w1.getWrkitmid());
        }
   }
    try {
        workItemRepository.save(w1);
    }
    catch (Exception e) {
        e.printStackTrace();
    }
    System.out.println(w1);
    return "success";
}

Объект WorkItem: 

@Entity

  1. Я вижу: "@GeneratedValue (стратегии = GenerationType.IDENTITY) private int linkingApplRefid;"
  2. Это означает, что значение генерируется БД, поэтому вам не нужно передавать какой-то идентификаторкогда вы отправляете запрос на создание (вставку) сценария.При такой конфигурации идентификатор передается только при обновлении какого-либо объекта.Из ваших журналов SQL кажется, что wrkitm вставлен, и после этого выполняется чтение для linkingApplRef с ID 1, которого нет в БД.
