Phantom 生成的“store”方法在运行时抛出 ClassCastException

Phantom's generated `store` method throws a ClassCastException at runtime

我有以下 Phantom table 定义:

package myPackage

import com.outworkers.phantom.CassandraTable
import com.outworkers.phantom.connectors.RootConnector
import com.outworkers.phantom.dsl._
import com.outworkers.phantom.keys.{PartitionKey, PrimaryKey}

import scala.concurrent.Future

case class KeysTwoThreeAndFour(myKeyTwo: Int, myKeyThree: String, myKeyFour: Int)

abstract class MyTable extends CassandraTable[MyTable, Int] with RootConnector {
  object myKeyOne extends IntColumn(this) with PartitionKey
  object myKeyTwo extends IntColumn(this) with PrimaryKey
  object myKeyThree extends StringColumn(this) with PrimaryKey
  object myKeyFour extends IntColumn(this) with PrimaryKey
  object myValue extends IntColumn(this)

  def insertValue(myKeyOne: Int, valuesMap: Map[KeysTwoThreeAndFour, Int]): Future[Unit] = {
    val resultFutures = for ((key: KeysTwoThreeAndFour, myValue) <- valuesMap) yield {
      store(myKeyOne, key.myKeyTwo, key.myKeyThree, key.myKeyFour, myValue).future()
    }


    Future.sequence(resultFutures).map { _ => () }
  }
}

编译正常,但在运行时抛出以下异常:

java.lang.ClassCastException: scala.Tuple5 cannot be cast to scala.runtime.Nothing$
    at myPackage.MyTable$anon$macro.store(MyTable.scala:10)
    at com.outworkers.phantom.CassandraTable.store(CassandraTable.scala:125) ~[com.outworkers.phantom-dsl_2.11-2.7.6.jar:2.7.6]
    at myPackage.MyTable$$anonfun.apply(MyTable.scala:19)
    at myPackage.MyTable$$anonfun.apply(MyTable.scala:18)
    ...

我正在按照幻影table docs底部的示例进行操作,似乎有什么问题?问题可能是我有一个简单的 Int 作为我的 "Record" 类型而不是实际的 class 吗?

我正在使用 phantom-dsl 2.7.6、Play Framework 2.3.10 和 Scala 2.11.11。

请注意,以下代码可以正常工作:

insert
.value(_.myKeyOne, myKeyOne)
.value(_.myKeyTwo, key.myKeyTwo)
.value(_.myKeyThree, key.myKeyThree)
.value(_.myKeyFour, key.myKeyFour)
.value(_.myValue, myValue)
.future()

谢谢。

问题似乎是由于 "Record" 类型是原始类型,而不是 class;换句话说,将我的 Int 包装在一个案例 class 中,该 Int 作为唯一的成员解决了问题。

另外,Select语句有问题,也解决了:
