Java 如何设置第n页'；在hibernate中的s权限和子权限？

我想知道使用Java8同时设置第n页权限和子权限的最佳方法是什么

这是Hibernate实体

    @Entity(name = "PERMISSION")
    public class Permission{
        @Id
        @Column(name = "PERMISSION_ID")
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long id;

        @Column(name = "PERMISSION_NAME")
        private String name;


        @NotFound(action = NotFoundAction.IGNORE)
        @ManyToOne(cascade={CascadeType.ALL})
        @JsonIgnore
        @JoinColumn(name="parent_id")
        private Permission parentId;

       @JsonSerialize(include = JsonSerialize.Inclusion.NON_EMPTY)
        @OneToMany(mappedBy = "parentId", fetch = FetchType.EAGER)
        private List<Permission> subPermission;

---

看看这个。这将起作用

private static List<Permission> set() {

        Permission parent = setParenPermission("Event");
        Permission parent1 = setParenPermission("Deals");
        Permission parent2 = setParenPermission("Movies");
        Permission parent3 =setParenPermission("Restaurant");
        Permission parent4 = setParenPermission("Outdoor");

        Permission child = setFirstLevel(parent, "Create");
        Permission child1 = setFirstLevel(parent, "Edit");
        Permission child2 = setFirstLevel(parent, "Update");
        Permission child3 = setFirstLevel(parent, "Delete");
        Permission subchild1 = setSecondLevel(child3,"Sub Delete");
