class AuctionActor extends CometActor {


  var highBid : TheCurrentHighBid = null

  override def defaultPrefix = Full("auction")

  val itemId = S.param("itemId").map(Long.parseLong(_)).openOr(0L)


  def render = {

    def itemView: NodeSeq = {

      val item = if (itemId > 0) 
        ItemMetaData.findByKey(itemId).openOr(ItemMetaData.create)
      else ItemMetaData.create
      val currBid = item.highBid
      val bidAmt = if (currBid.user.isEmpty) 0L else currBid.amount.is
      highBid = TheCurrentHighBid(bidAmt, currBid.user.obj.openOr(User.currentUser.open_!))
      val minNewBid = highBid.amount + 1L
      val button = <button type="button">{S.?("Bid Now!")}</button> %
      ("onclick" -> ajaxCall(JsRaw("$('#newBid').attr('value')"), bid _))
      (<div>
          <strong>{item.name}</strong>
          <br/>
          <div>
            Current Bid: ${highBid.amount} by {highBid.user.niceName}
          </div>
          <div>
            New Bid (min: ${minNewBid}) :
            <input type="text" id="newBid"/>
            {button}
          </div>
          {item.description}<br/>
       </div>)
    }

    bind("foo" -> <div>{itemView}</div>)

  }


  def bid(s:String): JsCmd = {

    val user = User.currentUser.open_!
    Auctioneer ! BidOnItem(itemId, Long.parseLong(s), user)

  }


  override def localSetup {

    Auctioneer !? AddListener(this, this.itemId) match {

      case Success(true) => println("Listener added")
      case _ => println("Other ls")

    }

  }


  override def localShutdown {

    Auctioneer ! RemoveListener(this, this.itemId)

  }


  override def lowPriority : PartialFunction[Any, Unit] = {

    case TheCurrentHighBid(a,u) => {
        highBid = TheCurrentHighBid(a,u)
        reRender(false)
      }
    case _ => println("Other lp")

  }


}

使用maven编译时发出以下错误：

[错误] AuctionActor.scala：64：错误：找不到：值Auctioneer [INFO]拍卖师！ BidOnItem（itemId，Long.parseLong（s），user） [INFO] ^ [错误] AuctionActor.scala：71：错误：未找到：value Auctioneer [INFO]拍卖师！？ AddListener（this，this.itemId）匹配{ [INFO] ^ [错误] AuctionActor.scala：83：错误：未找到：值Auctioneer [INFO]拍卖师！ RemoveListener（this，this.itemId）

Auctioneer class（LiftActor），使用以下行调用：

import org.developerworks.actor ._

任何人都知道我做错了什么

请帮助

Answer 1

将Auctioneer定义为类而不是对象吗？在这种情况下，您需要先实例化actor，然后才能使用它。

错误：未找到：value Auctioneer（LiftActor）
