支付模块

实际开发工作中经常会遇见如下场景，一个支付模块，一个订单模块，有一定依赖，一个同事负责支付模块，另一个同事负责订单模块，但是开发支付模块的时候要依赖订单模块的相关类，方法，或者工具类，这些还没开发出来，看不到一个完整的订单业务逻辑，可能只拿到了订单的Order类，但是呢不能影响我们后端的并行开发，就像前端和后端之间的并行开发，后端之间也有并行开发，后端的项目有时候是非常大的，这个时候该怎么办，本章支付模块和下节订单模块就要模拟这种场景，提高自己的胜任跨业务开发的抽象开发能力，这种能力再开发大型项目的时候非常重要，而且是衡量一个优秀开发者非常重要的标准，比如在面试的时候经常会问到这样问题来此判断这个面试者是否有开发大型项目的经验或者潜力，与此同时，还有一个重要目的，为了考虑后面的进阶课程，会把项目演进到拆分微服务和进行dubbo服务化的时候，我们只能拿到一个接口和一个类，什么都看不到，具体的实现都在远程的rpc服务端，这种场景的开发正是需要跨业务的一定抽象开发能力

查询支付状态

支付宝对接对接流程

1、首先得有一个支付宝账号，（注册蚂蚁金服开发平台账号）

2、创建应用，因为我们是自己开发或者公司开发，所以要创建自研型应用（自研型应用分为网页移动应用，AR，生活号，小程序），创建应用得过程中:

a) 需要一个用户名和一个logo(应用图标，因为我是自己学习，可以在线网站免费设计一个)，填写完毕之后确认创建，之后就可以在应用列表中看到创建得应用，一般情况下会进入下一个页面填写应用的更多详细信息

file

b) 进入下面页面

file

c) 关于应用网关和授权回调地址，单纯的支付接口是不需要配置这两个信息的，简单来说就是：应用网关是用于接收口碑或是生活号的信息的，授权回调地址是第三方授权或是用户信息授权使用的，如果用不到是可以不配置的！

d) 下面就静等审核（说是一个工作日）

涉及知识点

熟悉支付宝对接核心文档，调通支付宝支付功能官方Demo
解析支付宝SDK对接源码
RSA1和RSA2验证签名及加解密
避免支付宝重复通知和数据校验
natapp外网穿透和tomcat remote debug
生成二维码，并持久化到图片服务器
