Java Vue+SpringCloud integration before and after the completion of Alipay payment (sandbox) operation process [detailed]
The realization of Alipay payment function in our project is actually very simple. Don't say much, come straight to the point!
preparation
Baidu enters Alipay official website
Choose me to be a developer
Click on the console and log in
Select sandbox
|Key configuration class
After entering the sandbox, we need to prepare the configuration class first
package com.alipay.config;
import java.io.FileWriter;
import java.io.IOException;
/* *
*Class name: AlipayConfig
*Function: basic configuration class
*Details: set account information and return path
*Revision date: April 5, 2017
*explain:
*The following code is only the sample code provided to facilitate the merchant's test. The merchant can write it according to the technical documents according to the needs of its own website, but it is not necessary to use the code.
*This code is for studying and studying Alipay interface only, providing a reference.
