当面付分为三种,不同的方式有着不同的使用场景,当面付的字面含义是面对面的付也就是买家当着卖家的面来付款。其中条码支付和扫码支付使用的最多,本文主要介绍这两种。
- 当面付条码支付(商家使用扫码设备扫描买家支付宝的付款码):条码支付是支付宝给到线下传统行业的一种收款方式。商户使用扫码枪等条码识别设备扫描用户支付宝钱包上的条码/二维码,完成收款。一般在超市、便利店、店铺等使用。扫码支付(买家使用支付宝扫一扫扫描卖家的二维码):指用户打开支付宝钱包中的“扫一扫”功能,扫描商户针对每个订单实时生成的订单二维码,并在手机端确认支付。一般在类似于无人售货机上使用,像地铁中的无人售货饮料机、医院中的自助挂号收费机等声波支付
在接入之前首先要熟悉一下当面付产品的业务文档:
- 当面付文档
- 沙箱当面付接入引导
- 快速接入
当面付SDK&Demo 拿到demo我们熟悉一下demo,就可以依葫芦画瓢了,集成到自己工程中来。
通过下载Demo可以看到有两个工程,一个是TradePayDemo,一个是TradePaySDK,集成SDK必须要使用alipay-sdk-java20161213173952.jar,而TradePaySDK是对alipay-sdk-java.jar的进一步封装,在TradePayDemo中可以看到已经对TradePaySDK打成了jar包依赖进来了,当然也可以将整个TradePaySDK的src目录拖入到自己工程中, 当然也可以不使用alipay-trade-sdk.jar直接使用alipay-sdk-java.jar来开发。
集成当面付即可以参考TradePayDemo中的Main.java也可以参考WebRoot下的jsp,这里参考JSP中的代码来集成。 这里注意一点:jsp中的最上面的注释,所有的jsp文件都是一样的,作者粘贴了也不知道改一下,吐槽一下:这Demo写的真不细心
- 条码付参考trade_pay.jsp
- 扫码付参考trade_precreate.jsp
- 退款参考trade_refund.jsp
- 交易查询参考trade_query.jsp

二:集成步骤
0. 创建应用、配置密钥
集成前需要先创建应用、配置密钥、回调地址等,具体操作请查看Spring Boot入门教程(三十五):支付宝集成-准备工作
1. 将Demo中的alipay-sdk-java和alipay-trade-sdk两个jar安装到本地maven仓库中
注意:将jar打到本地maven仓库时命令行最好是一行,不好有回车换行, 这里使用2017版本的,不是2016版本的,Demo中的还是2016的版本。
mvn install:install-file -DgroupId=com.alipay -DartifactId=alipay-sdk-java -Dversion= 20170725114550 -Dpackaging=jar -Dfile=alipay-sdk-java-20170725114550.jar
mvn install:install-file -DgroupId=com.alipay -DartifactId=alipay-trade-sdk -Dversion=20161215 -Dpackaging=jar -Dfile=alipay-trade-sdk-20161215.jar
2. 引入依赖
<!-- alipay begin -->

3. 配置application.yml
注意:配置appPrivateKey和alipayPublicKey时值不要换行,returnUrl在当面付中不是必须的 注意:这里的returnUrl和notifyUrl在测试的时候需要外网能访问,可以通过natapp来实现
