微信、支付宝二码合一扫码支付实现思路（java）

人气:0

一、支付二维码（预订单）

根据需要购买的信息创建预订单，将订单信息保存到Redis中，并设置有效期，注意生产二维码的链接后的参数可以关联到Redis中的key；

QRCode  为servlet扫码请求的URL；

UUIDUtils.getUUID()  为预订单单号，在servlet请求中截取，然后在Redis中查找对应的Key的数据；

二维码地址：http://kung900519.qicp.io/interface/QRCode/UUIDUtils.getUUID()；

二、创建二维码扫码请求地址servlet：QRCodeServlet；微信支付重定向请求servlet：WechatPayServlet；支付宝重定向请求servlet：AliPayServlet；

QRCodeServlet  用于用户使用微信或者支付宝扫码二维码进行客户端识别及重定向到对应的业务处理；

 ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
 HttpServletRequest request = attributes.getRequest();
 Map<String, String> params = convertRequestParamsToMap(request); // 将异步通知中收到的待验证所有参数都存放到map中
 String paramsJson = JSON.toJSONString(params);
 logger.info("支付宝支付回调，{" + paramsJson + "}");
 try {
  SysPayChannel channel = payChannelService.selectByChannelType(PayTypeConstant.Alipay);
      MyAliPayConfig aliPayConfig = new MyAliPayConfig();
      aliPayConfig.setAppId(channel.getAppid());
      String certsrc = channel.getPayCertUrl();
      Properties propertiesFile = PropertiesUtils.getPropertiesFile(certsrc);
