Controller for springboot that redirects any url to /

ForwardingController.java

@Controller
public class ForwardingController {

    @RequestMapping("/**/{path:[^\\.]+}")
    public String forward() {
        // path: checks only the path of url
        // [^\.]: any char, except literal dot (because if the url is foo.css (for example) we don't want to redirect)
        return "forward:/";
    }
