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

这是测试/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：package 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 测试失败并出现以下错误（没有可用的详细跟踪）：[error] x 应该返回成功 [error] ' [error] [error] [error] Error 500 com.acme.TestController [error] [error] [error]

HTTP 错误：500

[错误]

访问 /api/account 时出现问题。原因：[错误] 

    com.acme.TestController

解决方案是将 spec2 行从：

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

到：

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

Swagger 注解导致控制器类是抽象的，不能实例化为声明的类型。这种映射 servlet 的替代方法有效
