文章标签 支付宝公钥应用私钥 java 支付宝当面付公钥证书 文章分类 运维

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 = RSA2

4、编码

不同支付方式，构造API请求和发送请求时需要调用不同的方法

当面付（条码支付）	AlipayTradePayRequest & AlipayTradePayResponse
当面付（线下扫码支付）	AlipayTradePrecreateRequest&AlipayTradePrecreateResponse
当面付	AlipayTradeCreateRequest&AlipayTradeCreateResponse
APP支付	AlipayTradeAppPayRequest & AlipayTradeAppPayResponse
手机网页支付	AlipayTradeWapPayRequest& AlipayTradeWapPayResponse
电脑网页支付	AlipayTradePagePayRequest& AlipayTradePagePayResponse
