scala - 无法加载 play.http.errorHandler - 未调用自定义处理程序

Question

我正在尝试根据文档在 Play Framework (2.6) 中加载自定义错误处理程序，但收到以下错误消息 -

无法加载 play.http.errorHandler

自定义错误处理程序 (app/services/ErrorHandler)

   package services

   import javax.inject.Singleton
   import play.api.http.HttpErrorHandler
   import play.api.mvc.Results._
   import play.api.mvc._

   import scala.concurrent._

   @Singleton
   class ErrorHandler extends HttpErrorHandler {

     def onClientError(request: RequestHeader, statusCode: Int, message: String) = {
       Future.successful(
         Status(statusCode)(
           message
         )
       )
     }

     def onServerError(request: RequestHeader, exception: Throwable) = {
       Future.successful(
         InternalServerError("A server errors occurred: " + exception.getMessage)
       )
     }
   }

应用程序.conf

   play.http.errorHandler = "com.mySite.services.ErrorHandler"

Answer 1

在您的代码中，包不是com.mySite.services. 只是services。

应用程序.conf

play.http.errorHandler = "services.ErrorHandler"
