支持swagger的scalatra应用程序的spec2测试失败

Question

在支持swagger的scalatra应用程序上调用原型spec3测试用例时，测试失败。

以下是测试/规范代码：ServletSpec.scala

class ServletSpec extends ScalatraSpec { def is =
  "Calling the generated swagger client"        ^
    "should return success"                     ! swaggerClient^
                                                end
  addServlet(classOf[TestController], "/api/*")
  def swaggerClient = get("/api/account") {
    status must_== 200
    response.body must_== 
      """my json response"""
  }  
}

TestController看起来像：包com.newco

import org.scalatra._
import org.scalatra.swagger._
//sample - see http://www.scalatra.org/guides/swagger.html
// JSON-related libraries
import org.json4s.{DefaultFormats, Formats}
// JSON handling support from Scalatra
import org.scalatra.json._
class TestController(implicit val swagger: Swagger) extends ScalatraServlet 
    with JacksonJsonSupport  with JValueResult {
  protected val applicationName = Some("AppName")
  protected val applicationDescription = "description."
   // Sets up automatic case class to JSON output serialization
  protected implicit val jsonFormats: Formats = DefaultFormats
  // Before every action runs, set the content type to be in JSON format.
  before() {
    contentType = formats("json")
  }
  val getAccount = 
    (apiOperation[GetAccountResponse]("getAccount")
      summary "Get users account information"
      notes "Returns the users profile"
      parameter queryParam[AccessToken]("accessToken").description("Access token returned from authentication service")
      )
  get("/account", operation(getAccount)){
      SampleData.getAccountResponse
  }
}

sbt测试失败，出现以下错误（没有可用的详细跟踪）：[error]x应返回成功[error]'[错误][错误][error]错误500 com.acme.TestController[错误][错误][error]

HTTP错误：500

[error]

访问/api/account时出现问题。原因：[error]

com.acme.TestController

[error]

---

由码头提供动力：//[error]
[错误][错误][error]'[error]不等于…

解决方案是将spec2行更改为：

addServlet(classOf[TestController], "api/*")

至：

implicit val swagger = new GPNSwagger 
addServlet(new TestController, "/api/*")

Swagger注释导致控制器类是抽象的，不能作为声明的类型实例化。这种映射servlet的替代方法适用于
