Springboot Hibernate & JPA 和 Native Queries (Group by PostgreSQL date_trunc) 可分页问题

Question

我在 SpringBoot 1.4.7 中遇到了这个 JPA 查询。 问题是我在尝试处理本机查询时收到此错误。 我已经测试了 SQL 查询并且都是有效的。

org.springframework.dao.InvalidDataAccessApiUsageException: Could not locate named parameter [signals], expecting one of [toDate, from, device]; nested exception is java.lang.IllegalArgumentException: Could not locate named parameter [signals], expecting one of [toDate, from, device]

查询定义为：

    @Query(value = "select device, signal, avg(avg), min(min), max(max), date_trunc('day', timestamp) as timestamp from  devicestatistics d "
            + "where timestamp between :from and :toDate and device like :device and signal IN (:signals) "
            + "group by d.device ,d.signal ,date_trunc('day' , d.timestamp ) order by device,date_trunc('day' ,d.timestamp) Desc \\n-- #pageable\\n",
            countQuery = "SELECT count(1) as NumRows from "
                    + "(select device, signal, avg(avg), min(min), max(max), date_trunc('day', :from) as timestamp from  devicestatistics d "
                    + "where 'time' between :from and :toDate and device like :device  "
                    + "group by device ,signal ,date_trunc('day' ,d.time ) order by device , date_trunc('day' ,d.time ), signal x"
            ,nativeQuery =  true)
    Page<DeviceStatistics> getDataDay(@Param("from") Date from, @Param("toDate") Date toDate, @Param("device") String device, @Param("signals") Collection<String> signals,Pageable page);

该表如下（我知道名称选择不明智）。

CREATE TABLE public.devicestatistics (
    device text NOT NULL,
    "TIMESTAMP" timestamp NOT NULL,
    signal text NOT NULL,
    avg float8 NULL,
    max int8 NULL,
    min int8 NULL,
    CONSTRAINT devicestatistics_pkey PRIMARY KEY (device, "TIMESTAMP", signal)
);

实体定义为：

@Getter
@Setter
@Entity
@Table(name = "DEVICESTATISTICS")
@IdClass(DeviceStatisticsID.class)
public class DeviceStatistics implements Serializable {

    @Id
    @Column(name = "DEVICE")
    private String device;

    @Id
    @Column(name = "SIGNAL")
    private String signal;

    @Column(name = "AVG")
    private double average;

    @Column(name = "MIN")
    private double minimun;

    @Column(name = "MAX")
    private double maximun;

    @Id
    @Column(name = "TIMESTAMP")
    @Temporal(TemporalType.TIMESTAMP)
    private Date time;

有什么提示吗？

这个问题类似于这个问题，但我希望使用本机查询 function。

谢谢！

编辑：

如果我停止使用 Pageable 它可以工作，但是我无法使用 Pageable 使其工作......（我一直在 stackoverflow 中搜索解决方案，但没有工作）

    @Query(value = "select device, signal, avg(avg), min(min), max(max), date_trunc('day', timestamp) as timestamp from  devicestatistics d "
            + "where timestamp between :from and :toDate and device like :device and signal IN (:signals) "
            + "group by d.device ,d.signal ,date_trunc('day' , d.timestamp ) order by device,date_trunc('day' ,d.timestamp) Desc",
            countQuery = "SELECT count(1) as NumRows from "
                    + "(select device, signal, avg(avg), min(min), max(max), date_trunc('day', :from) as timestamp from  devicestatistics d "
                    + "where 'time' between :from and :toDate and device like :device  "
                    + "group by device ,signal ,date_trunc('day' ,d.time ) order by device , date_trunc('day' ,d.time ), signal x"
            ,nativeQuery =  true)
    List<DeviceStatistics> getDataDay(@Param("from") Date from, @Param("toDate") Date toDate, @Param("device") String device, @Param("signals") Collection<String> signals);

Answer 1

最后我得到了它。 如果有人需要通过分组进行这种原生查询，这可能会有所帮助。

   @Query(value = "select device, signal, avg(avg), min(min), max(max), date_trunc('day', timestamp) as timestamp from  devicestatistics d "
            + "where timestamp between :from and :toDate and device like :device and signal IN (:signals) "
            + "group by d.device ,d.signal ,date_trunc('day' , d.timestamp ) order by device,date_trunc('day' ,d.timestamp) Desc --#pageable\n" ,
            countQuery = "SELECT count(1) as NumRows from "
                    + "(select device, signal, avg(avg), min(min), max(max), date_trunc('day', timestamp) as timestamp from  devicestatistics d "
                    + "where timestamp between :from and :toDate and device like :device and signal IN (:signals) "
                    + "group by device ,signal ,date_trunc('day' ,d.timestamp ) order by device , date_trunc('day' ,d.timestamp ) Desc) x"
            ,nativeQuery =  true)
    Page<DeviceStatistics> getDataDayIn(@Param("from") Date from, @Param("toDate") Date toDate, @Param("device") String device, @Param("signals") Collection<String> signals, Pageable page);
