一：簡介
手機網站支付的流程圖：
使用者點選H5應用中的支付按鈕點選支付按鈕會請求後臺介面，後臺介面請求支付寶的支付介面，支付介面會返回一段html程式碼其中包括一個form表單和一段js程式碼用於自動提交表單，表單提交後就會自動跳轉到支付寶的支付頁面(如果手機中裝了支付App就去開啟APP，如果沒有就在網頁版支付支付成功後會呼叫支付時設定的同步url, 然後跳轉到商戶的後臺系統，一般情況下商戶系統會展示一下支付成功，以及購買的商品資訊等檢視流程圖
二：整合步驟0. 建立應用、配置金鑰
整合前需要先建立應用、配置金鑰、回撥地址等，具體操作請檢視Spring Boot入門教程(三十五):支付寶整合-準備工作
