Question

I would like to write a Spring MVC HandlerInterceptorAdaptor which does different things in the postHandle() method based on wether the HttpResponse is a redirect or not.

Is this possible, and if so how?

public class MenuInterceptor extends HandlerInterceptorAdapter {
public final void postHandle(HttpServletRequest request,
                       HttpServletResponse response,
                       Object handler,
                       ModelAndView modelAndView) throws SystemException {
    if (redirect) {
        // do somethnig
    } else {
        // do something else
    }
}

EDIT:
Is there a better way than this:

if (modelAndView.getView() instanceof RedirectView || modelAndView.getViewName().startsWith("redirect:")) {
    // Do something
 } else {
    // Do something else
 }

Answer 1

In Spring MVC, a controller typically sends a redirect by returning a View that is a RedirectView or a String viewName that starts with the redirect: prefix. You can easily check for either of these.
