        if (request.getHeader("Access-Control-Request-Method") != null && "OPTIONS".equals(request.getMethod())) {
            // CORS "pre-flight" request
            response.addHeader("Access-Control-Allow-Origin", "*");
            response.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
            response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
            response.addHeader("Access-Control-Max-Age", "1800");//30 min
        }
        //This will filter your requests and responses.
        filterChain.doFilter(request, response);
    }
