youlai-boot

Enterprise-grade permission management backend based on Spring Boot 4

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
