Introduction
youlai-boot is an enterprise-grade permission management backend built on Spring Boot 4. It ships with the frontend vue3-element-admin and the mobile app youlai-app, and is one of 7 language implementations (Java / Node.js / Go / Python / PHP / C# / Rust) that share the same API specification and database schema. It is suitable for learning, reference, and secondary development of enterprise admin systems.
Core Features
- 🔐 Security — Spring Security + JWT/Redis dual-session model, token renewal, multi-device mutual exclusion
- 🛡️ Fine-grained permissions — 5-level RBAC: data → menu → button → API → field
- ⚡ Code generator — one-click generation of full-stack CRUD code
- 📦 Complete modules — users, roles, menus, departments, dictionaries, files, scheduled tasks, message center, operation logs
- 🌐 Multi-tenant SaaS — data isolation + tenant config, with a standalone youlai-boot-tenant edition
- 🔌 Real-time communication — SSE push: online user count, dictionary sync, notification broadcast
