Java生鮮電商平臺-支付模塊的設計與架構

Java生鮮電商平臺-支付模塊的設計與架構

 

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。 數據庫表設計。

 

說明：不管是支付寶仍是微信支付，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。

            好比：誰付款的，何時付款的，訂單號多少，是支付寶仍是微信，支付狀態是支付成功仍是支付失敗，仍是未支付。

      

           特別注意：訂單主表也有相似的回調信息。這樣用多張表記錄相應的信息，能夠統計相應的業務指標，包括用戶的行爲分析等。

 

            關於表的設計，個人經驗分享是：若是能夠，核心業務表必定要有一個日誌記錄表，若是能夠，能夠用時間軸等方式進行數據的插入，與時間軸的顯示。

            時間軸能夠清楚的知道用戶的行爲點，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以下：（注意，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。
