我正在尝试创建EnvironmentinSilhouette但无法创建。我已经定义了IdentityandAuthenticator如下

trait SessionEnv extends Env {
  type I = User
  type A = SessionAuthenticator
}

接下来，我想我必须创建Environment. 为此，我编写了以下代码，但我坚持，因为我不明白如何传递Environment'sapply方法预期的不同参数

环境伴生对象的应用方法有签名

   def apply[E <: Env](
  identityServiceImpl: IdentityService[E#I],
  authenticatorServiceImpl: AuthenticatorService[E#A],
  requestProvidersImpl: Seq[RequestProvider],
  eventBusImpl: EventBus

我知道我必须提供IdentityService. 我已经这样做了

class UserService @Inject()(userDao:UsersRepository) extends IdentityService[User] {...}

用户定义如下

case class UserProfile(
                    loginInfo:LoginInfo,
                    confirmed: Boolean,
                    email:Option[String],
                    firstName: Option[String],
                    lastName: Option[String],
                    passwordInfo:Option[PasswordInfo]
                    //oauth1Info: Option[OAuth1Info],
                    //avatarUrl: Option[String]) {
                  )

//representation of a user. A user has an Id and a profile
case class User (id:UUID, profile:UserProfile)

但是对于应用所需的其他值，我应该传递什么-authenticatorServiceImpl：AuthenticatorService[E#A]，requestProvidersImpl：Seq[RequestProvider]，eventBusImpl：EventBus

val sessionEnv = com.mohiva.play.silhouette.api.Environment[SessionEnv](new UserService(userRepository),????)

另外，我想我不必使用Guice，因为我正在使用编译时注入。那是对的吗？

更新我从更改SessionAuthenticatorService为CookieAuthenticatorService尝试一些在线可用的代码。

似乎我对Silhouette提供一些默认实现的理解并不完全正确。我以为我可以简单地使用中SessionAuthenticatorService定义的伴随对象，https://github.com/mohiva/play-silhouette/blob/master/silhouette/app/com/mohiva/play/silhouette/impl/authenticators/SessionAuthenticator.scala但事实并非如此。查看在 中创建的一些代码ScalaModule，似乎我必须自己创建所需的对象，但我需要在我的 AppLoader 类（用于编译时 DI）而不是 ScalaModule（用于运行时 DI）中创建。但是，我仍然没有解决问题。我不知道如何创建signer所需的CookieAuthenticatorService

val config = configuration.underlying.asInstanceOf[CookieAuthenticatorSettings]("silhouette.authenticator")
  val fingerprintGenerator = new DefaultFingerprintGenerator(false)
  val idGenerator = new SecureRandomIDGenerator()
  val clock:Clock = Clock()

  val authenticatorService: AuthenticatorService[CookieAuthenticator] = new CookieAuthenticatorService(config,None,,,fingerprintGenerator, idGenerator,clock) //STILL NEED TO FIND OUT HOW TO CREATE Signer AND CookieHeaderEncoding required by CookieAuthenticator service


 val cookieEnv = com.mohiva.play.silhouette.api.Environment[CookieEnv](userIdentityService ,authenticatorService,Seq(),EventBus())

这是cookie验证器的实现

    LoggerConfigurator(context.environment.classLoader).foreach {

    }
    new AppComponents(context).application

  val userIdentityService = new UserService(userRepository) //responsible for retrieving user information (eg email id) from a database

  val config =  CookieAuthenticatorSettings() 
  val fingerprintGenerator = new DefaultFingerprintGenerator(false)

  lazy val userWSRoutes = new WSRouters.User.UserRouter(userRepositoryController) //TODOM - whatam i doing here?

  lazy val router = new Routes(httpErrorHandler, homeController,userWSRoutes, countController,asyncController, assets)

}
