SWAK: A Swiss‑Army‑Knife‑Style Multi‑Implementation Framework for Xianyu Backend

SWAK is a lightweight, Spring-compatible framework that treats product type, category, and region tags as rules, registers multiple implementations during startup, and at runtime selects the appropriate one via priority and reduction, eliminating tangled if-else code, improving reuse, onboarding, and performance for Xianyu’s backend.
