Redirect unknown requests to index.html in springboot

Question

I\'m trying to get an Angular2 app served up through a springboot web application. I\'ve found lots of examples of how to do this very simply:

As a work-a-round I've added the Angular Routes in a RequestMapping annotation and pointed them all at the index.html:

@RequestMapping({"/login", "/logout"})
public String index() { return "index.html"; }

Edit: As a better work-a-round, you can make the controller implement ErrorController, override the getErrorPath method, then add a mapping for /error which will act as a catch-all (or mapping missing) method.

@Controller
public class TheOneController implements ErrorController {

    @RequestMapping("/error")
    public String index() {
        return "index.html";
    }

    @Override
    public String getErrorPath() {
        return "index.html";
    }
}

Now the index method will handle anything that can't be found and render the index.html.
