youlai-boot

Enterprise-grade permission management backend based on Spring Boot

Introduction

youlai-boot is an enterprise-grade permission management backend built on Spring Boot. 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 token 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 (OSS/RustFS/local), scheduled tasks, message center, operation logs

• 🔀 Workflow — Flowable approval flows: online BPMN design, conditional gateways, role-based approval, rejection & rollback

• 🌐 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

Quick Start

Requirements: JDK 17+ · MySQL 8.0+ · Redis 6.0+

1. Clone the project:

   git clone https://gitee.com/youlaiorg/youlai-boot.git
   

2. Import the database:

   # Base schema (required)
   sql/youlai-admin.sql
   
   # Optional extensions: safe to skip, run after the base schema
   sql/extensions/dynamic-form.sql # Dynamic Form
   sql/extensions/workflow.sql     # Workflow (Flowable demo processes & demo accounts, not engine tables)
   

3. Adjust config (optional, a read-only online data source is configured by default):

   src/main/resources/application-dev.yml
   

4. Start the service:

   Option 1: Run in IDEA (recommended) Open the project in IDEA, wait for Maven dependencies to download, then run the application class YouLaiBootApplication.

   Option 2: Command line

   mvn spring-boot:run
   

   Once started, visit http://localhost:8000/doc.html. If the API docs open, the backend is running properly.

5. Start the frontend (optional): For a visual admin UI, start the companion frontend vue3-element-admin, visit http://localhost:3000, and log in with admin / 123456.

Optional Extensions

Workflow (disabled by default)

Two steps to enable:

1. Import the demo data (demo processes & demo accounts):

   sql/extensions/workflow.sql
   

   The ACT_* engine tables do not need to be imported — Flowable creates them automatically on startup (existing tables are left untouched).

2. Enable it in application-{profile}.yml:

   workflow:
     enabled: true
   

   The Flowable engine switches (process / idm / eventregistry) follow workflow.enabled via placeholders in the same application-{profile}.yml, no extra maintenance needed.

Multi-tenant

For tenant isolation and tenant configuration, use the standalone repo youlai-boot-tenant.
