Jeepay: An Open‑Source Backend Payment System for Internet Enterprises

Jeepay is an open‑source payment system designed for internet enterprises, supporting multi‑channel services including WeChat Pay , Alipay , and UnionPay through official APIs and offering aggregated QR code payments.

The platform is built with Spring Boot and Ant Design Vue , integrating Spring Security for permission management, and follows a clear front‑end/back‑end separation to facilitate secondary development.

Key features include multi‑channel routing, V2/V3 interfaces for WeChat, RSA/RSA2 signatures for Alipay, distributed deployment, high concurrency support, MQ‑based order notifications, automatic generation of channel parameter configuration, and a concise management UI for both the operation platform and merchant system.

System architecture diagrams illustrate the overall structure and the aggregated payment flow, while the core technology stack highlights the use of Spring ecosystem components.
