推荐答案

您必须将其放入Play应用的conf文件夹中.

You have to put it in the conf folder of your Play app.

您还可以使用conf目录中的子文件夹.

You can also use subfolder in the conf directory.

例如:

conf/foo/bar.txt

可以使用以下方式访问

:

can be accessed using:

InputStream in = MyClass.class. getResourceAsStream("/foo/bar.txt")

您还可以通过更新project/Build.scala文件并添加以下内容来在应用中添加自定义资源目录:

You can also add a custom resources directory in your app, by updating your project/Build.scala file and adding:

val main = play.Project(appName, appVersion, appDependencies).settings(
      ...
      resourceDirectory in Compile <<= baseDirectory / "myresources"
      ...
  )
