How to get the names of all fonts in the controller in Spring?

Question

Java

Good afternoon. You need to get the paths to all the fonts in the /resources folder in the controller and transfer them to the html template. There are no problems with the transfer, but I can not receive.
If you write the path C:\Users\home\Desktop\fonts\src\main\resources\assets\fonts\hello.otf, then everything works, but I would like the application to determine the path itself on the server.
Here is the structure

And as in the template include styles?
How do I get files now

@GetMapping
    public String main(Map<String, Object> model) {

        String path = "src/main/resources/assets/fonts";

        File folder = new File(path);
        File[] listOfFiles = folder.listFiles();
....

You can use PathMatchingResourcePatternResolver :

ClassLoader classLoader = this.getClass().getClassLoader();
ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(classLoader);
Resource[] resources = resolver.getResources("classpath*:assets/fonts/*") ;
for (Resource resource: resources){
    ...
}
