Build Alipay Payments with Spring Boot: A Complete Guide

Hello, I’m TJ, a programmer who loves sharing useful open‑source tools.

Spring‑Boot Alipay Payment Demo

The spring-boot-pay project is a plug‑and‑play example for learning Alipay payment services. It supports QR code, PC, WAP, and APP payment scenarios.

Prerequisites

Alipay testing normally requires enterprise certification; you can also use the service‑provider mode to obtain a personal merchant account for testing.

JDK 1.8
