How to get http response status code from microservice - zuul [java]

Question

I developed a PreFilter for Zuul which does some checks on a request containing a JWT and if every checks goes OK, routes the request to the target Microservice.

What I'd like to do is to get the response HTTP status code.

I'm trying to develop a PostFilter in charge of getting the HTTP status code, but I'm stuck on it.

public class PostFilter extends ZuulFilter {

    @Override
    public boolean shouldFilter() {
        // TODO Auto-generated method stub
        return true;
    }

    @Override
    public String filterType() {
        // TODO Auto-generated method stub
        return "post";
    }

    @Override
    public int filterOrder() {
        // TODO Auto-generated method stub
        return 2;
    }

    @Override
    public Object run() throws ZuulException {

        RequestContext ctx = RequestContext.getCurrentContext();

        HttpServletResponse response = ctx.getResponse();

        int statusCode = response.getStatus();

        System.out.println(statusCode);

        return null;
    }

} 

The System.out.println() statement prints 0 .

How can I solve it? Thank you guys.

而是使用： context.getResponseStatusCode()
