使用JPA CascadeType更新根实体时，更新嵌套实体（ManyToOne）

Question

我创建了一些表来存储有关 personel 和 personel_egitim_durum 的信息，这些信息是非常嵌套的，并且实现了BaseEntity 。因此，数据库中的表也是嵌套的。 顶层实体称为“人员”。

当我将 personel 的字段更新为 aktif （来自BaseEntity 的）时，我希望 personel_egitim_durum 的 aktif （来自BaseEntity ）的字段会自动更新。

如下，

    @MappedSuperclass
    public abstract  class BaseEntity {
        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long id;

        @Column(name="eklenme_tarihi")
        @CreationTimestamp
        private Date eklenmeTarihi;

        @Column(name="guncellenme_tarihi")
        @UpdateTimestamp
        private Date guncellenmeTarihi;

        @Column(name="aktif")
        private int aktif;

        @Column(name="ekleyen_personel_id")
        private Long ekleyenPersonelId;

        @Column(name="guncelleyen_personel_id")
        private Long guncelleyenPersonelId;

//getter and setter
}

@Entity
@Table(name="personel")
public class Personel extends BaseEntity {

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="kisi_id")
    private Kisi kisi;

    @Column(name="personel_tipi",length = 2,nullable = false)
    private int personelTipi;

    @Column(name="sicil_no",length = 100,nullable = false)
    private String sicilNo;

    @Column(name="khk_onay",length = 1)
    private int khkOnay;
    //getter and setter
    }

    @Entity
@Table(name = "personel_egitim_durum")
public class PersonelEgitimDurum extends BaseEntity {

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name="personel_id",nullable = false)
    private Personel personel;

    @Column(name = "ogrenim_durumu")
    private String ogrenimDurumu;

    @Column(name = "okul_id", length = 3)
    private Long okulId;

    @Column(name = "universite_bolum_id", length = 4)
    private Long universiteBolumId;

    @Column(name = "mezuniyet_tarihi")
    private Date mezuniyetTarihi;

    @Column(name = "aciklama", length = 500)
    private String aciklama;

 //getter and setter
        }
