1、在支付宝开放平台下载当面付demo后，修改Alipay SDK版本为4.11.21.ALL或最新版（demo的3.3.0版本不支持证书方式）
<!-- https://mvnrepository.com/artifact/com.alipay.sdk/alipay-sdk-java -->
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.11.21.ALL</version>
</dependency>
2、导入bcprov-jdk*.jar包，否则会报错： java.lang.ClassNotFoundException: org.bouncycastle.jce.provider.BouncyCastleProvider
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk16</artifactId>
<version>1.46</version>
</dependency>
3、修改zfbinfo.properties （正式环境时，这三个证书应该单独存放在另一个文件夹，不要打包到jar）
# 支付宝网关名、partnerId和appId
open_api_domain = https://openapi.alipaydev.com/gateway.do
mcloud_api_domain = http://mcloudmonitor.com/gateway.do
#商户UID
pid = 20***913
appid = 2***565
# 应用私钥
private_key = MII****SkAgE
# 应用公钥证书 绝对地址
certPath = E:/****/CSR/appCertPublicKey_2021000117600565.crt
# 支付宝根证书 绝对地址
rootCertPath = E:/****/CSR/alipayRootCert.crt
#SHA256withRsa对应支付宝公钥证书 绝对地址
alipayPublicCertPath = E:/****/CSR/alipayCertPublicKey_RSA2.crt
# 签名类型: RSA->SHA1withRsa,RSA2->SHA256withRsa
sign_type = RSA24、编码
