前言：最近開發(fā)支付寶支付功能，總結(jié)一下做個(gè)分享
官方文檔：https://opendocs.alipay.com/apis
支付寶沙箱地址： https://openhome.alipay.com/platform/appDaily.htm?tab=info
支付寶支付流程：
準(zhǔn)備工作：獲取支付寶沙箱數(shù)據(jù)（appid，支付寶網(wǎng)關(guān)，rsa2秘，沙箱支付賬號(hào)等）
集成springboot，使用java代碼發(fā)起支付請(qǐng)求
支付寶收到支付請(qǐng)求后，返回html代碼片段，用于前端展示二維碼
掃碼支付成功后，支付寶發(fā)送同步、異步通知請(qǐng)求，同步、異步通知路徑可在配置文件中進(jìn)行配置
收到異步通知結(jié)果后，進(jìn)行驗(yàn)簽，驗(yàn)簽通過，返回成功信息通知支付寶不在進(jìn)行異步通知
此時(shí)支付寶支付流程完成，調(diào)用支付寶查詢接口，確認(rèn)支付成功
一、獲取支付寶沙箱數(shù)據(jù)
打開上述沙箱地址，獲取沙箱配置，查看下圖信息
二、集成springboot，使用java代碼發(fā)起支付請(qǐng)求
1、在pom.xml文件添加支付寶依賴

2、在項(xiàng)目中新建一個(gè)支付寶工具類
