来自 Akka 关闭 JVM 的错误，因为 ActorSystem 启用了 'akka.jvm-exit-on-fatal-error' [play-dev-mode] java.lang.Sta

Question

当我在IntelliJ中启动play/scala应用程序时，出现以下错误Uncaught error from thread [play-dev-mode-akka.actor.default-dispatcher-2]: null, shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled for ActorSystem[play-dev-mode] java.lang.StackOverflowError at play.api.BuiltInComponents.httpRequestHandler(Application.scala:321)

错误发生在以下代码行lazy val httpRequestHandler: HttpRequestHandler = new DefaultHttpRequestHandler(router, httpErrorHandler, httpConfiguration, httpFilters: _*)。不过这不是我的代码。我可以在堆栈跟踪(apploader.scala)中看到的代码的第一个条目是

lazy val userController = new UserController(credentialsProvider,application.configuration, utilities,userRepository, userTokenRepository,mailerService,controllerComponents, silhouetteJWTProvider,messagesApi,langs)

UserController定义如下：class UserController (credentialsProvider:CredentialsProvider,config:Configuration, utilities:HelperMethods, userRepo: UsersRepository,userTokenRepo:UserTokenRepository, mailerService:MailerService, cc: ControllerComponents, silhouette: Silhouette[JWTEnv],messagesApi: MessagesApi,langs:Langs)(implicit exec: ExecutionContext) extends AbstractController(cc){

我已经看到了SO的解决方案，它显示了如何禁用该功能(在java中为actorsystem禁用akka.jvm-exit-on-fatal-error)，但我认为允许jvm运行StackOverflowError不是一个好主意。我不知道是什么导致了这个问题。

为什么我会收到错误？对我来说，代码似乎在某种循环中运行，因为堆栈跟踪是重复的。

我还没有完全调试这个问题，但似乎我应该使用BuiltInComponentsFromContext提供的configuration对象而不是application.configuration.我将userRepository定义更改为以下内容，代码有效。

lazy val userController = new UserController(credentialsProvider,configuration, utilities,userRepository, userTokenRepository,mailerService,controllerComponents, silhouetteJWTProvider,messagesApi,langs)
