Java Web接入支付宝扫码付款API（使用SDK证书配置properties ）

一、支付宝当面付功能Demo

官方文档https://docs.open.alipay.com/194/106078/

ps：因为沙箱环境一经配置了证书公钥则无法重置

第一步下载项目SKD&Demo

点击下载

 解压后笔者使用的是eclipse，直接导入

一个TradePayDemo项目，一个是alipay-trade-sdk-20161215.jar的源码项目- TradePaySDK项目

笔者直接删掉了alipay-trade-sdk-20161215.jar依赖，使用项目依赖TradePayDemo添加，TradePaySDK项目

这样就可以直接点击查看源码方法实现的内容，主要实现运行Demo项目里面的main方法，跑得起来不报错就OK了

二、修改配置

 找到zfbinfo.properties文件配置

话不多说直接看注释跟下载的对比区别增加了，证书路径配置

怎么搞证书看这里 证书密钥

# 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
pid = #沙箱环境的话有个UID就是了
appid =  #你的APPID

# RSA私钥、公钥和支付宝公钥
private_key = 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

# 当面付最大查询次数和查询间隔（毫秒）
max_query_retry = 5
query_duration = 5000

# 当面付最大撤销次数和撤销间隔（毫秒）
max_cancel_retry = 3
cancel_duration = 2000

# 交易保障线程第一次调度延迟和调度间隔（秒）
heartbeat_delay = 5
heartbeat_duration = 900

然后改TradePaySKD项目

里面的初始化方法增加证书字段配置

注意部分：

 需要增加依赖包

 低版本的删掉，此处为TradePaySDK项目依赖

重点使用证书时调用的响应方法不同

 原调用的是execute需更改certificateExecute

运行测试
