Simple Spring Boot Application - HttpServletResponse needed

I want the simplest spring boot application like...

@Path("/")
@Component
public class RestResource {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/hello")
    public String hello() {
        return "Hello World";
    }
}

I want to build a REST application and I need the HttpServletResponse because I want to check some conditions and then do a redirect for example.

@Context
private HttpServletResponse servletResponse;

...

if (...)
    servletResponse.setStatus(HttpServletResponse.SC_BAD_REQUEST);
    servletResponse.sendRedirect(...);
else
    servletResponse.setStatus(HttpServletResponse.XYZ);
    servletResponse.sendRedirect(...);

What is the best way to get the HttpServletResponse in a Spring Boot application?
