Spring 使用 querydsl 的嵌套路径的数据休息顺序

Question

我想 order 使用 Nested Path

不工作

curl -i -X GET  http://localhost:8080/api/appointment?sort=doctor.name,{desc|asc} // Not working

虽然这个工作

curl -i -X GET  http://localhost:8080/api/appointment?sort=appointmentDay,{desc/asc} // working

curl -i -X GET  http://localhost:8080/api/appointment?dcotor.name=Ahmed // working

实体

public class Appointment implements Serializable {

    @Column(name = "appointment_day")
    @Future(message = "Day of appointment must be in the future!")
    @NotNull
    @Temporal(javax.persistence.TemporalType.TIMESTAMP)
    @JsonFormat(pattern = Constants.DATE_PATTEN)
    @DateTimeFormat(iso = ISO.DATE)
    private Date appointmentDay;

    @ManyToOne(optional = false)
    @JoinColumn(name = "doctor_id", nullable = false)
    private Doctor doctor;
    // Other properties 
    //
}

存储库

@RepositoryRestResource(path = "appointment", collectionResourceRel = "data", excerptProjection = AppointmentExcerpt.class)
public interface AppointmentRepo extends JpaRepository<Appointment, Long>, 
QueryDslPredicateExecutor<Appointment>, QuerydslBinderCustomizer<QAppointment> {}

更新 paging-and-sorting.adoc

Sorting by linkable associations (i.e. resources to top-level resources) is not supported.

但是我看到那是固定的here

更新添加了 3.0.0.M2 报告该问题已解决，但仍然 无法正常工作

Changes in version 3.0.0.M2 (2017-04-04)

DATAREST-976 - Sorting by an embedded property no longer works in Ingalls RC1.

刚刚降级 spring.data.‌rest.webmvc 到 Hopper 发布

<spring.data.jpa.version>1.10.10.RELEASE</spring.data.jpa.version>
<spring.data.rest.webmvc.version>2.5.10.RELEASE</spring.data.rest.webmvc.version>

/api/appointment?sort=doctor.name,{desc|asc} // works with (.)
/api/appointment?sort=doctor_name,{desc|asc} // works too  with (_)

谢谢@Alan Hay comment on

Ordering by nested properties works fine for me in the Hopper release but I did experience the following bug in an RC version of the Ingalls release.bug in an RC version of the Ingalls release. This is reported as being fixed,

jira issue - Sorting by an embedded property no longer works in Ingalls RC1

顺便说一句，我试过 v3.0.0.M3 报告已修复但无法与我一起使用。
