Error in URL Mapping in Spring MVC + Java Servlets

Question

In my sample Java/Spring-MVC/Webapp( github project ), When I try to open [ http://localhost:8080/bookflix/querybook.html][2] , I see a page.

Loading http://localhost:8080/bookflix/querybook.html happens smoothly
Hitting 'Search' button drives the browser to load http://localhost:8080/bookflix/query and leads to a 404.

I do not understand why GET/bookflix/query leads to a 404. Can anyone help me in fixing this. My github project is linked above. Code snippets below.

QueryController.java

... imports here ...
@Controller
public class QueryController {

    @RequestMapping(value="/bookflix/query", method=RequestMethod.GET)
    public void helloWorld(HttpServletRequest request, HttpServletResponse response) {
        ....
    }
}

After some debugging I realized the issue.
I was using an extraneous /bookflix/ everywhere, which was leading into incorrect URL namespace. Removed that, and the application worked.
This github commit fixes the problem.

Thanks for helping.
