entitymanager 不会保留所有电话以供联系
entitymanager will not persist all phones for contact
我有以下实体。
接触。人。组织。和 Telefoon(Phone 英文)。
一个人和一个组织都是联系人。他们继承自联系人。
一个联系人可以有一个或多个电话号码。所以来自 Telefoon 的列表。
组织也有来自类型人员的联系人。
问题是如果我坚持个人对象和组织对象,
每个对象都有 2 个数字,对于某些对象,数据库中只保留 1 个电话号码?怎么样?
我知道这与我的注释和我的 classes 配置有关。
class联系人

我以这种方式持久化我的对象:
persoon1.addTelefoon(new Telefoon("Huis","092243851"));
persoon1.addTelefoon(new Telefoon("Mobiel","0478451226"));
persoon2.addTelefoon(new Telefoon("Huis","095547812"));
persoon2.addTelefoon(new Telefoon("Mobiel","0425154578"));
persoon3.addTelefoon(new Telefoon("Huis","097784152"));

organisatie3.addTelefoon(new Telefoon("Huis","09784561346"));
organisatie3.addTelefoon(new Telefoon("Mobiel","0476112233"));
em.getTransaction().begin();
em.persist(persoon1);
em.persist(persoon2);
em.persist(persoon3);
em.persist(persoon4);
em.persist(persoon5);
em.persist(organisatie1);
em.persist(organisatie2);
em.persist(organisatie3);
em.merge(contactpersoon1);
em.merge(contactpersoon2);
em.merge(contactpersoon3);
em.getTransaction().commit();
但是数据库不会显示所有家庭号码和手机号码!
有些被遗漏了!
有什么想法吗?
谢谢
我找到了答案。
Glassfish 在数据库中保存日期时遇到问题。
class 人的日期 属性 由 class 转换我自己写的。只是为了编辑数据库中日期的标记。
glassfish 似乎无法处理。
我还删除了带有 Organisatie(组织)列表的 oneToMany。
这个:
@Entity
@Table(name="Persoon")
@Inheritance(strategy= InheritanceType.JOINED)
public class Persoon extends Contact implements Serializable{
@Convert(converter=LocalDatePersistenceConverter.class)
private LocalDate geboorteDatum;
protected Persoon() {}
@OneToMany(mappedBy="contactPersoon",orphanRemoval=true,cascade = CascadeType.ALL)
private List<Organisatie> Organisaties;
现在是这样的:
@Entity
@XmlRootElement
public class Persoon extends Contact implements Serializable {
@Temporal(DATE)
private Date geboorteDatum;
public Persoon() {
}
}
现在一切正常!
谢谢
