我有一个奇怪的问题。我有一个用 Play 编写的应用程序！框架 2.0.4。它使用一些公共资产（css/images/javascript）。当我在开发模式下运行它时一切都很好：
blus@vmblus:~/svn/blus> play
[info] Loading project definition from /home/blus/svn/blus/project/project
[info] Loading project definition from /home/blus/svn/blus/project
[info] Set current project to blus (in build file:/home/blus/svn/blus/)

[blus] $ run
--- (Running the application from SBT, auto-reloading is enabled) ---
[info] play - Listening for HTTP on port 9000...
(Server started, use Ctrl+D to stop and go back to the console...)
资产在浏览器中加载没有任何问题。但是当我想在生产模式下运行同一个应用程序（不复制，不移动，只是一样）时，资产就消失了：
[blus] $ start 9000
(Starting server. Type Ctrl+D to exit logs, the server will remain in background)
Play server process ID is 6845
[info] play - Application started (Prod)
[info] play - Listening for HTTP on port 9000...
萤火虫显示：
"NetworkError: 404 Not Found - http://vmblus:9000/assets/stylesheets/main.css"
没有找到所有需要的资产。这怎么可能？我能做些什么来解决这个问题？
这是我的一部分conf/routes：
GET /assets/*file controllers.ExternalAssets.at(path="public", file)
这就是我如何在视图中调用我的资产：
<link rel="stylesheet" media="screen" href="@routes.ExternalAssets.at("stylesheets/main.css")">
我看到了这个问题，但我的路径没有//。
