Reading Files from public folder in play framework in production

[itmstu...@gmail.com]

My play app is in 2.4.2. In Developer Mode,I used to read files from public folder at back-end controllers using Source.fromFile("./public/files/abc.json")

When I converted the application to production mode, I am getting File Not Found Exceptions. 

I found that the public folder is packed in an assets jar in production mode.

What can i do so that it works in both development and production mode??

How do you load it ? That's pretty essential. I only found using Environment.getFile("/path") to be working OK in both prod and dev mode. I personally don't use the Public folder, or any of that : I load and serve myself. All because I was to lazy to find out what the correct way was to load assets from the public folder on prod mode.

I simply use Source.fromFile function to get the file, nothing else.

Could you please suggest me the other way you are talking about?

I have tried Play.classloader.getResourceAsStream(fileName+".json") but that too is returning null.

It would be great if you could help me get it done by using Source.fromFile itself.

Dear Igmar,

I resolved it.

This is how I did it:-

1) Copy all files from public folder in conf folder. In Production mode,Play's class loader can read files only from conf folder.
2) Get resource as stream using Play's classloader.

3) Convert this inputstream to bufferedsource using Source.fromInputStream method.

 

Now, this file can be used by the controller for processing.

However,I would like to know some better way using which we do not have to copy these files from public folder to conf folder.

Did you find any other way to do this ?

@rahul, yes.

You can add the following lines in build.sbt to add any folder in distribution version:-

import com.typesafe.sbt.packager.MappingsHelper

mappings in Universal ++= directory(baseDirectory.value / "pulic")

Like this, any folder can be included in dist version(i)
