java - How to Implement HTTP byte-range requests in Spring MVC

Question

I have the problem with video rewind on my site.

I figure out that problem with http headers.

My current controller method which returns video:

@RequestMapping(method = RequestMethod.GET, value = "/testVideo")
@ResponseBody
public FileSystemResource testVideo(Principal principal) throws IOException {
   return new FileSystemResource(new File("D:\oceans.mp4"));
}

How to rewrite following code with byte-range supporting?

P.S.

I have seen following example http://balusc.blogspot.in/2009/02/fileservlet-supporting-resume-and.html

But this code looks hard for me and I cannot understand it. I hope that in spring mvc exists way simpler.
