我正在尝试使用akka.http.scaladsl.testkit.ScalatestRouteTest创建一个简单的测试，结果是：

class FooRoutesSpec extends FlatSpec with Matchers with ScalatestRouteTest with FooResource {

  Get(s"/foos/1") ~> fooRoutes ~> check {
      status shouldBe OK
    }
}

更新堆栈跟踪

An exception or error caused a run to abort: akka.http.scaladsl.server.RequestContextImpl.<init>(Lakka/http/scaladsl/model/HttpRequest;Lakka/event/LoggingAdapter;Lakka/http/scaladsl/settings/RoutingSettings;Lscala/concurrent/ExecutionContextExecutor;Lakka/stream/Materializer;)V

构建.sbt

libraryDependencies ++= {
  val Json4sVersion     = "3.2.11"
  val akkaV       = "2.4.16"
  val akkaHttpV   = "3.0.0-RC1"
  val scalaTestV  = "3.0.1"
  Seq(
    "com.typesafe.akka" %% "akka-slf4j"                 % akkaV,
    "com.typesafe.akka" %% "akka-http"                  % akkaHttpV,
    "com.typesafe.akka" %% "akka-http-testkit"          % akkaHttpV,
    "com.typesafe.akka" %% "akka-testkit"               % akkaV,
    "ch.qos.logback"    %  "logback-classic"            % "1.1.2",
    "org.json4s"        %% "json4s-native"              % Json4sVersion,
    "org.json4s"        %% "json4s-ext"                 % Json4sVersion,
    "de.heikoseeberger" %% "akka-http-json4s"           % "1.4.2",
    "org.scalatest"     %% "scalatest"                  % scalaTestV % "test"
  )
}

我能看到的是RequestContextImpl需要一个RequestContext

package akka.http.impl.server
    private[http] final case class RequestContextImpl(val underlying : akka.http.scaladsl.server.RequestContext) extends scala.AnyRef with akka.http.javadsl.server.RequestContext

但是 RequestContext 是一个类而不是特征

package akka.http.javadsl.server
class RequestContex

知道如何解决这个问题吗？

akka-http-json4s正在拖入旧版本的 Akka-HTTP（即 2.0.1 根据config）。

有一个更新akka-http-json4s的版本 1.11.0。这使用 Akka-HTTP 10.0.0 和 Akka 2.4.14（根据config）。

尝试碰撞所有依赖项：

  val akkaV       = "2.4.14"
  val akkaHttpV   = "10.0.0"
  val akkaHttpJson= "1.11.0"

（最后使用的版本"de.heikoseeberger" %% "akka-http-json4s" % akkaHttpJson）
