如何在spring boot中使用mongo repository按日期查询？

Question

我用mongo reposotory在spring boot中开发了一个应用程序。我正在使用spring数据jpa。我在许多表中声明了createDate作为日期工具包在java中，而日期存储在db中作为ISO格式。当我使用mongo存储库 findByCreatedDate（日期日期）查询时，没有结果。

以下是我的模型类

@Document
public class BarModel extends BaseEntity {

    @NotNull
    @Size(min = 2, max = 140)
    String name;
    String address;
    String city;
    String state;
    String zipcode;
    String phone;
    String description;
    String primImage;
    @DBRef
    Location location;
    @DBRef
    List<Special> specials;

}

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public abstract class BaseEntity {

    @Id
    private String id;

    @CreatedBy
    private String createdBy = getCurrentAuditor();

    @CreatedDate
    @DateTimeFormat(iso = ISO.DATE_TIME)
    private Date creationTime = new Date();

    @CreatedBy
    @LastModifiedBy
    private String modifiedBy = getCurrentAuditor();

    @CreatedDate
    @LastModifiedDate
    @DateTimeFormat(iso = ISO.DATE_TIME)
    private Date modificationTime = new Date();
}

@Transactional
public interface BarModelRepository extends MongoRepository<BarModel, String> {

    Page<BarModel> findByCreationTime(Pageable pageable, Date creationtime);

    public List<BarModel> findByCreationTime(Date from, Date to);
}
