【问题描述】：

我在 Global.scala 中添加了一些代码，以及 application.conf application.global=Global

object Global extends WithFilters(new GzipFilter()) with GlobalSettings {
  override def onStart(app: Application) {
    Logger.info("Application started.")
  }

  override def onStop(app: Application) {
    Logger.info("Application shutdown...")
  }
}

为什么在 conole 中运行 3 次？

[info] application - Application started.
[info] application - Application started.
[info] application - Application started.
[info] wobo - Application started (Dev)
[WARN] [10/21/2013 15:54:50.591] [New I/O worker #1] [EventStream(akka://play)]akka.event-handlers] config is deprecated, use [akka.loggers]
[info] application - Application shutdown...
[info] application - Application shutdown...
[info] application - Application shutdown...

【解决方案1】：

OnStart is might called multiple times because you have dependencies to Play plugins that are older than your application Play version.

您可以在 SBT 中排除较旧的 Play 依赖项，例如如何为 build.sbt 或 Build.scala 中的类型安全邮件插件执行此操作：

 "com.typesafe" %% "play-plugins-mailer" % "2.2.0" exclude ("org.scala-stm", "scala-stm_2.10.0") exclude("play", "*")

我认为这是因为 Play 有一个新的 Group ID，所以 SBT 无法将其识别为同一个库。
