How do I set up Spring MVC to catchAll requests and just return my welcome page (index.html)?

My overall intention is to use Spring MVC to intercept anything with "/api/" so that I can make calls to the backend, but any other url should return "index.html" so that ui-router can attempt to show the correct view.

However with my current setup I can navigate around the site using ui-router but when I attempt to navigate to a url that should be resolved by ui-router I get this error:

```
Problem accessing /app/hi/hello. Reason:
Circular view path [index.html]: would dispatch back to the current handler URL 
[/app/hi/index.html] again. Check your ViewResolver setup! (Hint: This may be the result 
of an unspecified view, due to default view name generation.)

```

My setup:

**BaseController.java**

```
@Controller
public class BaseController {

    @RequestMapping("/app/**")
    public String get() {
       return "index.html";
    }
}

```

**web.xml**
