直接打印信息到页面
resultMap.put(Constants.Attrs.ERR_CODE, Constants.Config.STR_500);
resultMap.put(Constants.Attrs.ERR_MSG, Constants.TipMsg.ORDER_NOT_EXIST);
response.getWriter().write(JSON.toJSONString(resultMap));

转发，1个request，
request.setAttribute(Constants.Attrs.Content, Constants.TipMsg.QRCODE_HAS_USED);
request.getRequestDispatcher("/alreadyUse.html").forward(request, response);

重定向 2个request，变地址
response.sendRedirect("https://open.weixin.qq.com/connect/oauth2/authorize?appid=" + appId + "&redirect_uri="+baseServer+"orderInfo/wxpay&response_type=code&scope=snsapi_userinfo&state=" + orderNum ); // + "&connect_redirect=1");

ModelAndView mv
mv.addAllObjects(resultMap);
mv.setViewName("error");
mv.setViewName("payDetail");

WebMvcConfigurer 配置HandlerInterceptor拦截器addInterceptors、静态资源映射addResourceHandlers、MultipartConfigElement等

BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
out.write(result.get("paySuccess").getBytes());
out.flush();
out.close();
