我刚刚从UI加载了Play Java Seed来创建一个新的应用程序。我在public/stylesheets/main.css中写了一些CSS代码，这是我对这个项目的唯一改变。在编译并运行应用程序后，Chrome控制台会显示
GET http://localhost:9000/assets/stylesheets/main.css 404 (Not Found)
GET http://localhost:9000/assets/javascripts/hello.js 404 (Not Found)
我已阅读资产控制器文档here，但无法弄清楚我出错的地方。
在我的main.scala.html文件中（与种子相同），我有：
<head>
<title>@title</title>
<link rel="stylesheet" media="screen" href="@routes.Assets.at("stylesheets/main.css")">
<link rel="shortcut icon" type="image/png" href="@routes.Assets.at("images/favicon.png")">
<script src="@routes.Assets.at("javascripts/hello.js")" type="text/javascript"></script>
</head>
在我的路线文件中（也与种子保持不变）：
# Map static resources from the /public folder to the /assets URL path
GET /assets/*file controllers.Assets.at(path="/public", file)
favicon显示在选项卡中，但当我转到http://localhost:9000/assets/images/favicon.png时，页面也不可用，就像使用main.css和hello.js脚本一样。

当从由以下创建的打包的tarball运行时，似乎也发生了（在游戏2.3.8中）
$ activator universal:package-zip-tarball
，然后..
$ [tarball-extract-path]/bin/[project-name]
在本地开发构建文件下载正常，但在远程测试服务器上我得到404（未找到）。

对我来说，当我开始制作项目时问题就消失了：
activator start
这只是一种解决方法，但我希望它可以帮助你们中的一些人。
我怀疑这是一个游戏中的错误，并希望在新游戏版本上消失。

如果您的版本中有LessKeys.compress := true，则您必须使用缩小版。
@routes.Assets.at("stylesheets/main.min.css")

运行从使用PlayFramework 2.3.7的typesafe.com下载的播放Java种子时，我没有任何问题
看看我做了什么并做同样的事情
