Question

我正在尝试使用spala 2.11喷涂一个简单的“hello world”服务器：

import spray.routing.SimpleRoutingApp
import akka.actor.ActorSystem

object SprayTest extends App with SimpleRoutingApp {
  implicit val system = ActorSystem("my-system")

  startServer(interface = "localhost", port = 8080) {
    path("hello") {
      get {
        complete {
          <h1>Say hello to spray</h1>
        }
      }
    }
  }
}

但是，我收到以下编译错误：

Multiple markers at this line
    - not found: value port
    - bad symbolic reference to spray.can encountered in class file 'SimpleRoutingApp.class'. Cannot 
     access term can in package spray. The current classpath may be missing a definition for spray.can, or 
     SimpleRoutingApp.class may have been compiled against a version that's incompatible with the one 
     found on the current classpath.
    - not found: value interface

有谁知道可能是什么问题？顺便说一下，我对喷雾和演员都很陌生，所以我对喷雾和演员的工作方式缺乏很多直觉（这就是为什么我要做这个简单的教程）。

终于找到了自己的答案。我需要在我的pom文件中添加spray-can依赖项。留下这个问题和答案，以防其他人遇到同样的问题。

SBT示例：

scalaVersion := "2.10.4"

val akkaVersion = "2.3.6"

val sprayVersion = "1.3.2"

resolvers ++= Seq(
    "Spray Repository" at "http://repo.spray.io/"
)

libraryDependencies ++= Seq(
    "com.typesafe.akka" %% "akka-actor" % akkaVersion,
    "io.spray" %% "spray-can" % sprayVersion,
    "io.spray" %% "spray-routing" % sprayVersion
)

使用scala 2.11的hello world spray应用程序出错
