Question

我是使用光滑工具的新手，我只是尝试从h2 db插入和提取数据，但是我得到了错误的时间戳格式这就是我要插入的内容：

FooRecord（1，foo，bar，a，b，c，2016-12-10 23：59：00.0,2016-12-10 23：59：00.0,2016-12-10 23：59：00.0，false）

这是select query的结果，您可以看到时间为零

FooRecord（1，foo，bar，a，b，c，2016-12-10 00：00：00.0,2016-12-10 00：00：00.0,2016-12-10 00：00：00.0，false）

这是我的表定义的样子

case class FooRecord (id: Long, firstName: String, lastName:String, parameter: String, value: String, unit: String,
                          validStart: Timestamp, validStop: Timestamp, transactionTime: Timestamp, archive: Boolean = false)

  private class FooTable(tag: Tag) extends Table[FooRecord](tag, "myTable") {
    def id = column[Long]("id", O.PrimaryKey, O.AutoInc)
    def firstName = column[String]("first_name")
    def lastName = column[String]("last_name")
    def parameter = column[String]("parameter")
    def value = column[String]("value")
    def unit = column[String]("unit")
    def validStart = column[Timestamp]("valid_start")
    def validStop = column[Timestamp]("valid_stop")
    def transactionTime = column[Timestamp]("transaction_time")
    def archive = column[Boolean]("archive")
    def * =
      (id, firstName, lastName, parameter, value, unit, validStart, validStop, transactionTime, archive) <> ((FooRecord.apply _).tupled, FooRecord.unapply)
  }

这是插入方法：

def create(firstName: String, lastName:String, parameter: String, value: String, unit: String, validStart: Timestamp,
             validStop: Timestamp, transactionTime: Timestamp, archive: Boolean = false): Future[FooRecord] = db.run {
    (records.map(p => (p.firstName, p.lastName, p.parameter, p.value, p.unit, p.validStart, p.validStop,p.transactionTime, p.archive))
      returning records.map(_.id)
combines our original parameters with the
      into ((rec, id) =>
      FooRecord(id, rec._1, rec._2, rec._3, rec._4,rec._5, rec._6,rec._7, rec._8, rec._9))
      ) += (firstName, lastName, parameter, value, unit, validStart, validStop, transactionTime, archive)
  }

这是选择查询：

def list(): Future[Seq[FooRecord]] = {
      sortedActiveRecords.result
  }

如何获取正确的时间戳，包括时间值（小时，分钟，秒）？

-----更新---- 查看日志，似乎插入语句可以： [debug] s.j.J.语句-准备插入语句（返回：id）：

insert into "myTable" ("first_name","last_name","parameter","value","unit","valid_start","valid_stop","transaction_time","archive")  values (?,?,?,?,?,?,?,?,?)
[debug] s.j.J.parameter - /--------+--------+--------+--------+--------+-----------------------+-----------------------+-----------------------+---------\
[debug] s.j.J.parameter - | 1      | 2      | 3      | 4      | 5      | 6                     | 7                     | 8                     | 9       |
[debug] s.j.J.parameter - | String | String | String | String | String | Timestamp             | Timestamp             | Timestamp             | Boolean |
[debug] s.j.J.parameter - |--------+--------+--------+--------+--------+-----------------------+-----------------------+-----------------------+---------|
[debug] s.j.J.parameter - | foo    | bar    | a      | b      | c      | 2016-12-10 23:59:00.0 | 2016-12-10 23:59:00.0 | 2016-12-09 23:59:00.0 | false   |
[debug] s.j.J.parameter - \--------+--------+--------+--------+--------+-----------------------+-----------------------+-----------------------+---------/

但是select查询看起来很奇怪-请注意它们确实没有时间戳值的时间戳值：

[debug] s.b.B.action - #1: result [select "id", "first_name", "last_name", "parameter", "value", "unit", "valid_start", "valid_stop", "transaction_time", "archive" from "myTable"]
[debug] s.j.J.statement - Preparing statement: select "id", "first_name", "last_name", "parameter", "value", "unit", "valid_start", "valid_stop", "transaction_time", "archive" from "myTable"
[debug] s.j.J.benchmark - Execution of prepared statement took 196µs
[debug] s.j.S.result - /----+------------+-----------+-----------+-------+------+-------------+------------+------------------+---------\
[debug] s.j.S.result - | 1  | 2          | 3         | 4         | 5     | 6    | 7           | 8          | 9                | 10      |
[debug] s.j.S.result - | id | first_name | last_name | parameter | value | unit | valid_start | valid_stop | transaction_time | archive |
[debug] s.j.S.result - |----+------------+-----------+-----------+-------+------+-------------+------------+------------------+---------|
[debug] s.j.S.result - | 1  | foo        | bar       | a         | b     | c    | 2016-12-10  | 2016-12-10 | 2016-12-09       | 0       |
[debug] s.j.S.result - \----+------------+-----------+-----------+-------+------+-------------+------------+------------------+---------/

光滑的h2 db时间戳是检索时区列，时间为零
