The integration steps
1. Preparation
-
Enter alipay sandbox environment to generate RSA2(SHA256) key as prompted
-
Get alipay – trade – sdkjar package
Download pay-in-person Demo from Alipay open platform
Obtain the jar package Alipay -trade- SDK-20161215.jar from the \TradePayDemo\WebRoot\ web-INF \lib path
-
Package jars into the Maven repository
Use the following command to package in the directory where the JAR package is located
mvn install:install-file -DgroupId=com.alipay -DartifactId=alipay-trade-sdk -Dversion=20161215 -Dpackaging=jar -Dfile=alipay-trade-sdk-20161215.jar Copy the code
