Java開源生鮮電商平臺-支付模塊的設計與架構(源碼可下載）
開源生鮮電商平臺支付目前支持支付寶與微信。針對的是APP端（android or IOS）
1。 資料庫表設計。
說明：無論是支付寶還是微信支付，都會有一個服務端的回調，業務根據回調的結果處理相應的業務邏輯。
pay_logs這個表主要是記錄相關的用戶支付信息。是一個日誌記錄。
比如：誰付款的，什麼時候付款的，訂單號多少，是支付寶還是微信，支付狀態是支付成功還是支付失敗，還是未支付。
特別註意：訂單主表也有類似的回調信息。這樣用多張表記錄相應的信息，可以統計相應的業務指標，包括用戶的行為分析等。
關於表的設計，我的經驗分享是：如果可以，核心業務表一定要有一個日誌記錄表，如果可以，可以用時間軸等方式進行數據的插入，與時間軸的顯示。
時間軸可以清楚的知道用戶的行為點，幫助更加清晰的設計業務流程與系統架構。
相應的支付寶回調代碼如下：（註意，這個業務模塊屬於買家。）

APP支付成功後，其實支付寶或者微信都會告訴你是否成功，只是這種通知是不可靠的，最可靠的的一種方式是支付寶或者微信的服務端回調。
根據回調處理相關的業務。
