将播放框架路由转换为Java URL类（用于初始化java.net.URL类）

Question

I want to play song in page when it opening. (I know It's a bad idea but I want to say Happy Birthday to my cousins :D ) for that I need to convert play framework routes to java.net.URL class. I tried these line of code but all of them gave me NULL pointer

URL url = app.getClass().getClassLoader().getResource( 
    "../../public/sounds/9-Baroon.wav");

URL url = app.getClass().getClassLoader().getResource(
    controllers.routes.Assets.at("sounds/9-Baroon.wav").absoluteURL(request()));

URL url = app.getClass().getClassLoader().getResource( 
    controllers.routes.Assets.at("sounds/9-Baroon.wav");

how can I get that music file?

Some word

I'm stupid. I think I had to use controller for playing sound but this must done in views. I don't remove this question because anyone make that mistake find his/her mistake sooner.

Answer 1

It has nothing to do with Play Framework. You want to play sound on the webpage directly from HTML (or with some Javascript).

So you don't need Java for it (though your still can serve your .wav file from Play Framework as static asset).
