@Configuration

    registration.setOrder(1);
    return registration;
}

public class CrosFilter implements Filter {
    @Override
    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain filterChain)
            throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) req;

        } else {
            filterChain.doFilter(request, response);
        }
