我正在开发一个rest API，该API提供一个端点来插入Rule and Items。我有一个名为rule的实体和另一个名为item的实体，例如波纹管：

Rule.java

@Getter
@Setter
@Entity
@Table(name = "rule")
public class Rule extends PhysicalBaseEntity {

    @NotNull
    @Column(name = "title")
    @Size(max = 100)
    private String title;

    @NotNull
    @Column(name = "description")
    @Size(max = 150)
    private String description;

    @OneToMany(cascade = {CascadeType.MERGE},orphanRemoval = true)
    @JoinColumn(name = "rule_id",nullable = false)
    private Set<Item> items;

}

Item.java

@Getter
@Setter
@Entity
@Table(name = "item")
public class Item extends PhysicalBaseEntity {

    @NotNull
    @Column(name = "code")
    @Size(max = 50)
    private String code;

    @NotNull
    @Column(name = "description")
    @Size(max = 150)
    private String description;

    @ManyToOne(cascade={CascadeType.ALL})
    @JoinColumn(name = "parent_id",referencedColumnName = "id")
    private Item parent;

    @OneToMany(mappedBy="parent",cascade={CascadeType.ALL})
    private Set<Item> children;

}

，我需要使用VO实体来表示该信息，但是我不知道如何ll create this VO's and I don不知道这种方法是否是最好的。 我的第一个想法是Rule实体发送所有信息，例如：

{
    "id": "55cfd101-3bc3-4842-a1ab-f88096b9ea06","title": "TITLE","description": "DESCRIPTION","items": [
        {
            "id": "fa1c8e5f-5791-491b-b1ee-4d09048608d6","code": "2","description": "PARENT","children": [
                {
                    "id": "755bed57-1581-4524-bae1-4ec648711a88","code": "000","description": "FIRST SON"
                    "children": [
                        {
                            "id": "1420ad3b-5278-48fe-a638-77a2e16feb39","code": "111","description": "SECOND SON"
                            "children": [
                                {
                                    "id": "f55cf8d1-b2e4-4a9e-9f79-df156a5ac0a4","code": "222","description": "THIRD SON"
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ]
}

这对我来说是最好的主意吗？
