没有Play插件的Play框架sbt-web集成 [英] Play Framework sbt-web integration without play plugin

问题描述

作为库嵌入游戏，我启用了sbt-web插件我的项目，并已运行web-stage，使资产逐字复制到target/web/stage/.但是，使用Play框架的字符串插值路由DSL 时，当匹配请求来自:

Embedding play as a library, I enabled the sbt-web plugin in my project, and have run web-stage, making assets copied verbatim to target/web/stage/. However using Play Framework's string interpolation routing DSL as follows, they are not served when a matching request comes in:

object PlayServer extends App {
    val server = NettyServer.fromRouter() {   
      case GET(p"/public/$file*") => {
        val path = "/target/web/stage"
        Assets.at(path = path, file = file)
    }
}

通过播放代码进行调试

Debugging through the play code handling Assets.at, it looks like nothing brings the assets into being resources under target/scala-2.11/classes/, where presumably play framework is trying to load them as resources from. Running sbt web-stage does not take care of specifically that.

那么sbt-web管理将资产放置在那里的缺失是什么?当手动放置在那里时，集成有效！！因此似乎sbt-web在其默认配置下，就Play而言，将资产放置在错误的目标子目录中...

So what is missing for sbt-web managing to take care of placing the assets there? When manually placed there, the integration works!! so it seems sbt-web in its default configuration places the assets in the wrong target subdirectory as far as Play is concerned...

请注意，在plugins.sbt中，我仅包含sbt-web中的以下内容，这够吗?

Please note that in plugins.sbt I include only the following from sbt-web, should that be enough?

addSbtPlugin("com.typesafe.sbt" % "sbt-web" % "latest.release")

推荐答案

将资产放置在/src/main/resources/assets/下，可以在运行时将其复制到target，从而绕过任何奇特的sbt-web处理.这使您摆脱了基本开发的泥潭.

Placing the assets under /src/main/resources/assets/ gets them copied to target upon running, bypassing any fancy sbt-web processing. This gets you out of the mud for basic dev.

路线需要像这样修改:

case GET(p"/public/$file*") => {
  val path = "/assets"
  Assets.at(path = path, file = file)
}

设置适当的sbt-web管道以进行最小化或最终无法避免的事情，因此，这并不是真正的答案，但是它可以解决内部使用的应用程序的某些用例.

Setting up a proper sbt-web pipeline for minification or whatever cannot ultimately be avoided, hence this is not really an answer, but it solves a certain use case using play for internally used applications.
