public void  getUnSignData(HttpServletRequest request, HttpServletResponse response){
        try {
                //这里拿到支付宝通知数据
                Map<String, String[]> requestParams = request.getParameterMap();
                for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {
                    String name = (String) iter.next();
                    String[] values = (String[]) requestParams.get(name);
                    String valueStr = "";
                    for (int i = 0; i < values.length; i++) {
                        valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";
                    }
                    // 乱码解决，这段代码在出现乱码时使用
                    // valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
                    params.put(name, valueStr);
                }
                //打印数据看看
                logger.debug("数据："+gson.toJson(requestParams));
                //获取其中一个值看看
                String notifyType = params.get("notify_type");
          } catch(Exception e){
                logger.error("error",e);
        }
        //支付宝要求必须返回success，不然就会一直给你回调
        PrintWriter writer = null;
        writer = response.getWriter();
        writer.write("success"); // 一定要打印success
        writer.flush();
        return;
        
     }
