前几天一直在研究java集成支付宝支付,今天就把研究成果分享一下,也便于以后遇到需要集成支付宝支付的时候,可以很快就集成出来。
1.准备一个支付宝账号,登录蚂蚁金服开放平台,按照下图步骤,创建好应用,添加相应需要开发集成的支付功能,搭建好开发环境。
1.1.此处重点讲一下配置应用环境时开发环境的配置,如下图
1.支付网关:图中所示的支付网关是正式环境的支付网关,也就是应用上线以后用真正的支付宝进行支付的应用网关。我们在开发阶段不急集成正式环境
,所以蚂蚁金服特地为我们准备了沙箱环境,沙箱环境的支付网关为https://openapi.alipaydev.com/gateway.do,待应用开发完成,换成正式网关即可。
2.应用网关:我们在生成订单以后,需要调用支付宝进行支付,如果支付成功,支付宝就会主动通知我们自身的系统支付结果,这个应用网关就是我们在调用
支付宝支付时传给支付宝的(支付宝有了他就可以把支付结果通知给我们)。应用网关必须外网可以访问,关于如何把内网转化为外网可以访问,网上有很多
教程,这里不做讲述。
3.授权回调地址:如果我们是服务商,替商家开发集成支付宝支付的时候,需要商家给我们授权,这就好比你用微信或者其他应用的信息登录另一款APP的时候
,会提示需要访问你的一些资料,需要你授权一样,这个地址,就是商家给我们授权以后,支付宝主动通知我们授权结果的地址。授权流程如下图
我们需要拼接授权链接给商户,由商户点击链接进行授权正式环境的授权链接；https://openauth.alipay.com/oauth2/appToAppAuth.htm?app_id=2015101400446982&redirect_uri=http%3A%2F%2Fexample.com
其中app_id为正式环境的app_id,redirect_uri就是上述的授权回调地址沙箱环境的授权链接:https://openauth.alipaydev.com/oauth2/appToAppAuth.htm?app_id=APPID&redirect_uri=REDIRECT_URI
其中app_id为沙箱环境的app_id,redirect_uri就是上述的授权回调地址
通过商家授权以后,最终我们会调用支付宝的接口获取到最终的授权令牌,通过该令牌替商家发起支付宝的下单,支付,退款,查询等请求。
4.接口加签方式:可以参照开放平台上的步骤,去下载加签工具,然后生成自己的私钥和公钥.并将公钥设置到此处,私钥自己严加保存。
2.开发环境搭建好以后,接下来就可以利用开发文档进行开发了.此处只以开发电脑网站支付功能为例进行讲解,其他功能类似。
开放平台上有各个功能的相关demo,下载下来以后集成到代码中即可,比较简单,下载下来demo以后
首先看看配置类
package cn.mrdear.pay.alipay;
import java.io.FileWriter;
import java.io.IOException;
/
类名：AlipayConfig
功能：基础配置类
详细：设置帐户有关信息及返回路径
修改日期：2018-05-29
说明：
以下代码只是为了方便商户测试而提供的样例代码，商户可以根据自己网站的需要，按照技术文档编写,并非一定要使用该代码。
该代码仅供学习和研究支付宝接口使用，只是提供一个参考。

到此,集成支付宝的电脑网站支付功能就集成完毕了。总结一下：
其实集成支付宝的支付很简单,基本上只要熟悉开发文档,一步步来,再加上我给出的这两段代码,基本上就可以轻松集成。
下节准备研究一下集成微信支付,微信支付貌似需要商户才能集成,个人不能够集成,这需要研究一下。
