spring 4.1 JSONP support

https://spring.io/blog/2014/07/28/spring-framework-4-1-spring-mvc-improvements

JSONP is now supported with Jackson.
For response body methods declare an @ControllerAdvice as shown below.
For View-based rendering simply configure the JSONP query parameter name(s)
on MappingJackson2JsonView.

@ControllerAdvice
private static class JsonpAdvice extends AbstractJsonpResponseBodyAdvice {

    public JsonpAdvice() {
        super("callback");
    }

}

다만. 아래와 같은 이슈가 있으니, 재정의가 좀 필요하다.
