在scala中找不到favicon.ico的问题

Question

我测试了一个播放2.3.4应用程序,并在控制台中抱怨以下内容:

! @6jg7imio5 - Internal server error, for (GET) [/favicon.ico] ->

play.api.Application$$anon$1: Execution exception[[NoSuchElementException: key not found: favicon.ico]]
    at play.api.Application$class.handleError(Application.scala:296) ~[play_2.10-2.3.0.jar:2.3.0]
    at play.api.DefaultApplication.handleError(Application.scala:402) [play_2.10-2.3.0.jar:2.3.0]

    at controllers.Application$$anonfun$list$1$$anonfun$apply$7$$anonfun$apply$8.apply(Application.scala:68) ~[classes/:2.3.0]

然后我搜索了所有源代码,找不到任何使用过的favicon.ico.它是否在某些库中使用？

我在浮油中使用的库.库配置如下:

libraryDependencies ++= Seq(
    "com.typesafe.play" %% "play-slick" % "0.7.0",
    "org.slf4j" % "slf4j-nop" % "1.6.4",
    "joda-time" % "joda-time" % "2.3",
    "org.joda" % "joda-convert" % "1.5",
    "com.github.tototoshi" %% "slick-joda-mapper" % "1.1.0",
    jdbc,
    anorm
)

更新:

oracle@SomeHost ~/activator-1.2.10/abb_web_1/public $ tree
.
??? images
?   ??? favicon.ico
??? javascripts
?   ??? forms.js
?   ??? jquery.js
??? stylesheets
    ??? bootstrap.min.css
    ??? main.css

在路径文件中,我根据biesior的回复添加了以下内容.但它仍然抱怨同样的错误.我把favicon.ico放在错误的地方？

GET     /favicon.ico                controllers.Assets.at(path="/public", file="favicon.ico")

Answer 1

favicon.ico访问该地址时,每个浏览器都会查找.只需将该文件添加到您的public文件夹并添加路线:

GET  /favicon.ico   controllers.Assets.at(path="/public", file="favicon.ico")

提示:它也可以是png文件 - 在默认的新PlayJava或PlayScala项目中可以找到它 public/images/favicon.png
