在IntelliJ / Play框架中为scala.html和路由文件突出显示语法

I am new to both IntelliJ and the Play framework. I noticed that after installing IntelliJ and importing my first Play application, syntax highlighting is not working properly for both *.scala.html files and the routes files. I was able to modify the settings for the *.scala.html files to have them recognized as Scala files, but this isn't actually correct because the scala templating system is not pure Scala.I am new to both IntelliJ and the Play framewor
