Playframework简介

Question

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

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...")
  }
}

为什么在康诺尔跑三次？

[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...

OnStart可能会被多次调用，因为您需要使用比应用程序播放版本更早的插件。

您可以在SBT中排除旧的Play依赖项，例如，如何对build.sbt或Build.scala中的类型文件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有一个新的组ID，所以SBT不承认它是同一个库。
