java - Play Framework 2.3.7 : Static assets location not working in production

Question

我看到了一些关于此的问题，但似乎无法深入了解。

我有一个 Play Framework 2.3.7 (Activator 1.2.12) 站点，当我在开发模式下运行它时一切正常。当我在生产模式下启动它时，出现以下错误:

问题似乎与 requirejs 及其 Assets 路径有关。第一个页脚错误的代码如下:

 <script data-main="@routes.Assets.at("javascript/admin.js")" type="text/javascript"      src="@routes.Assets.at("lib/requirejs/require.js")"></script>

我的 Assets 路由文件是:

# Map static resources from the /public folder to the /assets URL path
GET         /assets/javascript/routes.js                  controllers.Application.javascriptRoutes()
GET         /assets/javascript/admin_routes.js            controllers.admin.Application.javascriptRoutes()
GET         /assets/*file                                 controllers.Assets.at(path="/public", file)

这是我的build.sbt

import WebKeys._
import RjsKeys._
import play.PlayJava

name := """app"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava, SbtWeb)

)

pipelineStages := Seq(rjs, digest, gzip)

RjsKeys.paths += ("jsRoutes" -> ("/jsroutes" -> "empty:"))

RjsKeys.paths += ("adminJsRoutes" -> ("/adminJsRoutes" -> "empty:"))

includeFilter in (Assets, LessKeys.less) := "*.less"

excludeFilter in (Assets, LessKeys.less) := "_*.less"

有人能给我指出正确的方向吗？干杯!

Answer 1

我已经找到了解决我自己问题的方法，不确定这是否是正确的方法，但这种方法对我有用。

• pipelineStages := Seq(rjs, digest, gzip) - 删除了 rjs，因为它在新的 Play 中不再需要
• Play Framework 的打包方式最近随着 Play Framework 的升级而改变，您现在可以使用 sbt 打包器来完成它。在这种情况下，它是“sbt docker:stage”
• 需要 docker.aws.json 文件来将公开端口映射到 aws beantalk 外部端口
• 需要在 docker 文件中添加权限行以允许 beantalk 部署脚本访问目录
• 链接到 windows 的 sbt 打包器中有一个错误，因为命令行有一个字符限制，这会受到影响。这就是为什么我不能使用激活器运行本地生产模式。这个错误仍然很突出，所以我不能在生产模式下在本地运行它
• docker 文件现在在 sbt 打包过程中生成，所以我将 docker 端口添加到 sbt.build 文件中。我需要找到一个命令添加到 sbt.build 中，它将执行 docker 文件中的权限行，以便我们可以使用 jenkins 脚本来自动化该过程

我发现很少有网站真正帮助了我:

• http://www.ronaldcirka.com/blog/2014/12/06/deploying-play-framework-to-elastic-beanstalk-in-docker/
• Why I receive permission denied in Docker deployment?
• Best way to deploy play2 app using Amazon Beanstalk

希望对某人有所帮助!
