Jeepay: Open‑Source Integrated Payment System Built with Spring Boot and Ant Design Vue

Jeepay is an open‑source integrated payment system designed for internet companies, supporting multiple channels such as WeChat Pay, Alipay and UnionPay.

It is built with Spring Boot on the backend and Ant Design Vue on the frontend, and uses Spring Security for permission management.

The name “Jeepay” originates from the original XxPay project; “Jee” represents the company name “计全科技” and “pay” denotes payment.

Key features include multi‑channel gateway routing, support for WeChat V2/V3 and Alipay RSA/RSA2 signatures, distributed deployment, high concurrency, signed request/response, MQ‑based order notifications, and a clear separation of operation platform and merchant system.

The system architecture separates the payment gateway, operation platform, and merchant system, all communicating via HTTP APIs and message queues.
