一:简介

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。

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

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 --> <dependency> <groupId>com.alipay</groupId> <artifactId>alipay-sdk-java</artifactId> <version>20170725114550</version> </dependency> <dependency> <groupId>com.alipay</groupId> <artifactId>alipay-trade-sdk</artifactId> <version>20161215</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> </dependency> <dependency> <groupId>commons-configuration</groupId> <artifactId>commons-configuration</artifactId> <version>1.10</version> </dependency> <dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>3.2.1</version> </dependency> <!-- alipay end --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency>

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
