Is it possible to serve a templated text file using spark? (java web framework)

Question

I am using spark as the backend to a project I am working on. I noticed that spark has the ability to serve templated html, using a templating engine such as velocity, freemaker, etc.

However, this isn't quite what I want. Instead of serving an html template, I would like to serve a plaintext file, while still allowing me to insert parameters where needed. For context, I am trying to allow the user to download code examples based on the parameters they have supplied.

Does anything like this exist, or do I need to essentially build the desired file's content and return it as a string?

Example of what I am trying to do

// example.java

public class Example {
    public static void main(String [] args) {
        System.out.println( {{ param }} );
    }
}

So this ^ would be the plain text template that I am attempting to serve... "param" would be passed to the backend via http request, and inserted into the file. Then I would serve the file to the frontend.

So, (as mentioned in the comment :), glad it helped) you can serve this content as HTML page (then you can use template manager) containing only this plaintext content only. Only exception will be the extension which will be .html instead of .java if the user saves the file.
