Question

我有一个停机时间实体。我正在为停机对象设置值，并将这些对象传递给 JpaReposirtory save(downtimeobject)方法。 save()插入重复记录。我参加了论坛，但是没有运气，我没有任何解决方案。现在，在将对象保存到数据库中之后，我正在检查是否插入重复项。如果插入，我将通过 JpaRepository delete(downtimeId)删除。

我的downitme实体

@Entity
@Table(name = "tDownTime")
public class DownTime {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "DowntimeId")
    private int downtimeId;

    @Column(name = "SiteId")
    private int siteId;

    @Column(name = "PlantId")
    private int plantId;

    @Column(name = "UnitId")
    private int unitId;

    @Column(name = "EquipmentId")
    private int equipmentId;

    @Column(name = "ShiftId")
    private int shiftId;

    @Column(name = "DownTimeReasonId")
    private Integer downTimeReasonId;

    @Column(name = "DownTimeReasonName")
    private String downTimeReasonName;

    @Column(name = "DownTimeReasonDescription")
    private String downTimeReasonDescription;

    @Column(name = "DownTimeStartDate")
    private LocalDate downTimeStartDate;

    @Column(name = "DownTimeStartTime")
    private LocalTime downTimeStartTime;

    @Column(name = "DownTimeEndDate")
    private LocalDate downTimeEndDate;

    @Column(name = "DownTimeEndTime")
    private LocalTime downTimeEndTime;

    @Column(name = "DownTimeDuration")
    private Long downTimeDuration;

    @Column(name = "HourResetTime")
    private LocalDateTime hourResetTime;

    @Column(name = "KPIDate")
    private LocalDate kPIDate;

    @Column(name = "CreatedBy")
    private String createdBy;

    @Column(name = "CreatedOn")
    private LocalDateTime createdOn;

    @Column(name = "ModifiedBy")
    private String modifiedBy;

    @Column(name = "ModifiedOn")
    private LocalDateTime modifiedOn;

    @Column(name = "SKUId")
    private int sKUID;

    @Column(name = "DownTimeStartDateTime")
    private LocalDateTime downTimeStartDateTime;

    @Column(name = "DownTimeEndDateTime")
    private LocalDateTime downTimeEndDateTime;

    @Column(name = "WorkOrderId")
    private int workOrderId;

    @Column(name = "IsManual")
    private boolean isManual;

    @Column(name = "AutoPauseResume")
    private boolean isAutoPauseResume;

    @Column(name = "DowntimeType")
    private String downtimeType;

    @Column(name = "DownTimeStatus")
    private String downtimeStatus;

DownTime downTime = new DownTime();// creating object for setting values to object to save as entity

downTime.setUnitId(calculationOEEHelper.getUnitId());   downTime.setEquipmentId(calculationOEEHelper.getEquipmentId());
downTime.setShiftId(calculationOEEHelper.getShiftId());
downTime.setDownTimeReasonId(0);
downTime.setDownTimeReasonName(ParameterTags.UNASSIGNED);
.
.
.

downTime = downtimeRepository.save(downTime);

它正在数据库中插入2个整数。我正在使用MSSQL DB

DownTime [downtimeId = 2148，siteId = 1，plantId = 1，unitId = 12，   equipmentId = 33，shiftId = 28，downTimeReasonId = 0，   downTimeReasonName =未分配，downTimeReasonDescription =未分配，   downTimeStartDate = 2019-05-11，downTimeStartTime = 06：36：42，   downTimeEndDate = 2019-05-11，downTimeEndTime = 06：37：23，   downTimeDuration = 41，hourResetTime = 2019-05-11T07：30：01，   kPIDate = 2019-05-11，createdBy = SYSTEM，   createdOn = 2019-05-12T01：06：55.865，ModifyBy = SYSTEM，   modifiedOn = 2019-05-12T01：06：55.865，sKUID = 5，   downTimeStartDateTime = 2019-05-11T06：36：42，   downTimeEndDateTime = 2019-05-11T06：37：23，workOrderId = 74，   isManual = false，isAutoPauseResume = true，downtimeType =未安排，   downtimeStatus =正在运行]

DownTime [downtimeId = 2149，siteId = 1，plantId = 1，unitId = 12，   equipmentId = 33，shiftId = 28，downTimeReasonId = 0，   downTimeReasonName =未分配，downTimeReasonDescription =未分配，   downTimeStartDate = 2019-05-11，downTimeStartTime = 06：36：42，   downTimeEndDate = 2019-05-11，downTimeEndTime = 06：37：23，   downTimeDuration = 41，hourResetTime = 2019-05-11T07：30：01，   kPIDate = 2019-05-11，createdBy = SYSTEM，   createdOn = 2019-05-12T01：06：55.865，ModifyBy = SYSTEM，   modifiedOn = 2019-05-12T01：06：55.865，sKUID = 5，   downTimeStartDateTime = 2019-05-11T06：36：42，   downTimeEndDateTime = 2019-05-11T06：37：23，workOrderId = 74，   isManual = false，isAutoPauseResume = true，downtimeType =未安排，   downtimeStatus =正在运行]

downtimeId不同，其余全部相同

可以帮助我解决这个问题。

我不确定我是否理解您要实现的目标，但这似乎是预期的行为。如果要更新对象而不是创建对象，则应从存储库中获取旧版本并在其上设置值。
