為什么 Jpa 排序不適用於 Spring 中的 Pageable？

Question

分頁工作正常，但我無法根據特定字段對數據進行排序。 我的存儲庫方法Page<AdvertSearch> findAll(Pageable pageable);

我的實體 class 是：

public class AdvertSearch {

    @Id
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    @Column(name = "id", nullable = false, columnDefinition = "VARCHAR(36)")
    private String id;

    private String advertId;
    private String officeId;
    private String officeName;

    //TODO: type hangi Point olacak hangi class olacak karar verilecek
    @Column(nullable = false, columnDefinition = "POINT SRID 4326")
    private Point location;

    private OfficeType officeType;
    private String city;
    private String district;
    private String mainOfficeId;
    private Integer facilityCount;
    private Integer virtualPackageCount;
    private BuildingType buildingType;
    private Integer securityCount;
    private Double monthlyPrice;
    private String currency;
    private Integer capacity;

    //TODO: officelerde rating olmayacak diye konustuk bunun da netlestirilmesi gerek
    private Double rating;
    private Integer ratingCount;
}

我的 postman 請求是： http://localhost:8080/advertsearch/findallbypage?page=0&size=4&sort=district&direction=desc

如您所見，我想根據地區對數據進行排序，但它不起作用。 我的要求錯了嗎？ 還是關於 JPA 中的Pageable ？

Answer 1

方向應該在排序參數中：

?page=0&size=4&sort=district,desc
