微信运挫、支付寶二碼合一掃碼支付實現(xiàn)思路

一、支付二維碼（預(yù)訂單）

根據(jù)需要購買的信息創(chuàng)建預(yù)訂單套耕，將訂單信息保存到Redis中谁帕，并設(shè)置有效期，注意生產(chǎn)二維碼的鏈接后的參數(shù)可以關(guān)聯(lián)到Redis中的key箍铲；

QRCode 為servlet掃碼請求的URL雇卷；

UUIDUtils.getUUID() 為預(yù)訂單單號鬓椭，在servlet請求中截取颠猴，然后在Redis中查找對應(yīng)的Key的數(shù)據(jù)；

二維碼地址：http://kung900519.qicp.io/interface/QRCode/UUIDUtils.getUUID()小染；

二翘瓮、創(chuàng)建二維碼掃碼請求地址servlet：QRCodeServlet；微信支付重定向請求servlet：WechatPayServlet裤翩；支付寶重定向請求servlet：AliPayServlet资盅；

QRCodeServlet 用于用戶使用微信或者支付寶掃碼二維碼進行客戶端識別及重定向到對應(yīng)的業(yè)務(wù)處理调榄；
