scala - Scala 中的导入

Question

我坚持以下代码：

trait Service extends Closeable {
  class STATE(value: Int, statename: String) extends Eumeration(value: Int, statename: String) {
    val NOTINITED =  Value(0, "NOTINITED")
    val INITED = Value(1, "INITED")
    val STARTED = Value(2, "STARTED")
    val STOPPED = Value(3, "STOPPED")
    override def toString() = statename
    type STATE = Value
  }
}

然后我创建了一个新类

import abc.event.Service

class ServiceStateModel(name: String) {
  val statemap: Array[Array[Boolean]] = Array(
    Array(false, true,  false,  true),
    Array(false, true,  true,   true),
    Array(false, false, true,   true),
    Array(false, false, false,  true))
}

在上面的代码编译器给了我一个警告

**Multiple markers at this line
- imported `Service' is permanently hidden by definition of trait Service in package event
- imported `Service' is permanently hidden by definition of trait Service in package event**

结果，我通过以下导入将其重命名Service为：SS

import abc.event.{Service => SS}

但现在SS连认不出来

PS 我的类路径中有 hadoop 库，它有一个名为 的接口Service，因此我导入了自己的Service特征。
