Question

应用程序从播放2.4.3迁移到2.7.0 我正在使用以下插件。

scalaVersion := "2.11.6"
sbt.version=1.2.7
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.7.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "4.1.0")

我正在跟踪堆栈跟踪：

我从2.4迁移到2.6。我相信最好一步一步做。首先，更新到2.5，然后更新到2.6和...。 Play Framework已记录了如何从一个版本迁移到下一个版本。链接： https://www.playframework.com/documentation/2.7.x/Migration25 https://www.playframework.com/documentation/2.7.x/Migration26 https://www.playframework.com/documentation/2.7.x/Migration27

但是针对您的特定问题https://www.playframework.com/documentation/2.7.x/Migration26#Scala-Configuration-API
