更新我的父对象时，数据库中的某些列变为空白

Question

当我尝试更新父类对象时，我在数据库中获取了一些空白字段

这是我尝试过的一些步骤，但仍然无法解决

@Entity
@Table(name="stores")
public class Store{

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    @OneToOne(mappedBy = "store", fetch = FetchType.LAZY,cascade=CascadeType.ALL )
    @JsonManagedReference
    private Config config;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public config getConfig() {
        return config;
    }

    public void setConfig(Config config) {
        this.config = config;
    }

}

@Entity
@Table(name = "config")
public class Config {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @OneToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL)
    @JoinColumn(name = "store_id")
    @JsonBackReference
    private Store store;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }


    public Store getStore() {
        return store;
    }

    public void setStore(Store store) {
        this.store = store;
    }

}

我从商店类中删除了cascade = CascadeType.ALL，但仍然无法解决此问题
