UUID疯狂与mssql

Question

我的数据库条目具有值的UUID(使用Microsoft SQL Server Management Studio提取)

CDF86F27-AFF4-2E47-BABB - 2F46B079E98B

将其加载到我的Scala应用程序后,toString方法会生成此值

276ff8cd-f4af-472e降低-BABB - 2f46b079e98b

这是怎么发生的？当我手边只有裸字符串CDF86F27-AFF4-2E47-BABB-2F46B079E98B时,如何以编程方式创建UUID实例？

相关的Slick代码(前者:表定义,后者:数据库访问对象)

class ChannelTable(tag: Tag) extends Table[ChannelTuple](tag, "Channel") {
  def id = column[UUID]("Id", O.PrimaryKey)
  def channelId = column[Int]("Channel_Id", O.NotNull)
  def timer = column[UUID]("Timer_Id", O.NotNull)
  def from = column[Timestamp]("FromTime", O.NotNull)
  def to = column[Timestamp]("ToTime", O.NotNull)
  def mon = column[Boolean]("Mon", O.NotNull)
  def tues = column[Boolean]("Tues", O.NotNull)
  def wed = column[Boolean]("Wed", O.NotNull)
  def thu = column[Boolean]("Thu", O.NotNull)
  def fri = column[Boolean]("Fri", O.NotNull)
  def sat = column[Boolean]("Sat", O.NotNull)
  def sun = column[Boolean]("Sun", O.NotNull)
  def * = (id, channelId, timer, from, to, mon, tues, wed, thu, fri, sat, sun)
}

object ChannelDAO extends EntityDAO[Channel, ChannelTuple] {
  private val entities = TableQuery[ChannelTable]
  [...]
  override def get(id: UUID)(implicit session: Session): Option[Channel] = {
    val y = for {
      a <- entities if a.id === id
    } yield (a)
    if (y.list.length > 1) throw new NonUniqueResultException
    y.firstOption
  }
  [...]
}

对我来说效果很好：

> val uuidString = "CDF86F27-AFF4-2E47-BABB-2F46B079E98B"
uuidString: String = CDF86F27-AFF4-2E47-BABB-2F46B079E98B

> java.util.UUID.fromString(uuidString)
res2: java.util.UUID = cdf86f27-aff4-2e47-babb-2f46b079e98b
