支付宝支付
支付宝推出了新的转账接口alipay.fund.trans.uni.transfer(升级后安全性更高，功能更加强大) ，老转账接口alipay.fund.trans.toaccount.transfer将不再维护，新老接口的一个区别就是新接口采用的证书验签方式。
使用新接口要将sdk版本升级到最新版本，博主升级时最新版本是4.10.97。
接下来看集成步骤。
将支付宝开放平台里下载的3个证书放在resources下面
写支付宝支付的配置文件
alipay.properties
alipay.appId=你的应用id alipay.serverUrl=https://openapi.alipay.com/gateway.do alipay.privateKey=你的应用私钥 alipay.format=json alipay.charset=UTF-8 alipay.signType=RSA2 alipay.appCertPath=/cert/appCertPublicKey_2021001164652941.crt alipay.alipayCertPath=/cert/alipayCertPublicKey_RSA2.crt alipay.alipayRootCertPath=/cert/alipayRootCert.crt
