Detailed explanation of Java integrated Alipay payment interface (JSP+ Alipay 20160912)

Make complaints about:

Alipay's interface and WeChat's DEMO and documents are really hard to understand and out of order. They don't know where to find their own things. In recent days, our company needs to do similar development. As a pioneer, I take the lead in solving the Java integration of Alipay payment and WeChat payment interface.

Our working environment: JSP website + payment interface, the current Alipay interface is 20160912, WeChat is V3 version, if there is a version upgrade, please contact the customer service staff of related agencies to upgrade.

This article introduces the JSP+ Alipay interface, which is not original.
