我只是想知道$ {applicaation.home}在哪里定义，因为它似乎没有在我的生产环境中定义.

I was just wondering where is the ${applicaation.home} defined, as it seems to not have been defined in my production environment.

推荐答案

如@ user316607所示，Play应该在编译时相关性注入，您需要按照ApplicationLoader中自己调用Logger.configure ="noreferrer">此博客文章:

As indicated by @user316607, Play should define application.home by itself in the Logger.configure method. If you are seeing the value application.home_IS_UNDEFINED instead, and you're using compile-time dependency injection, you'll need to call Logger.configure yourself in your ApplicationLoader as explained in this blog post:

class MyApplicationLoader extends ApplicationLoader {
  def load(context: Context) = {
    new MyComponents(context).application
  }
}

class MyComponents(context: Context) extends BuiltInComponentsFromContext(context) {
  // You have to call Logger.configure manually or logback won't work
  Logger.configure(context.environment)

  // ... The rest of your app initialization code ...
}
