Spring返回json可以跨域设置

if (request.getHeader(HttpHeaders.ORIGIN) != null) {

            String origin = request.getHeader("Origin");

            response.addHeader("Access-Control-Allow-Origin", origin);

            response.addHeader("Access-Control-Allow-Credentials", "true");

            response.addHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT,PATCH, HEAD");

            response.addHeader("Access-Control-Allow-Headers", "Content-Type");

            response.addHeader("Access-Control-Max-Age", "3600");

        }
