Overview of eladmin: An Open‑Source Spring Boot + Vue Backend Management System

The article introduces eladmin , an open‑source backend management system based on Spring Boot 2.1.0, JPA, Spring Security, Redis and Vue, featuring a front‑back separation, RBAC permission control, data dictionary, dynamic routing, and one‑click generation of front‑end and back‑end code.

The project is stable, continuously optimized by its author, and fully open source; its back‑end code quality and database design are commendable, while the front‑end uses the widely adopted Vue framework, making it easy to get started.

System Functions

User Management – add users with default password 123456.

Role Management – assign permissions and menu items, with department‑based data permissions.

Menu Management – dynamic routing configurable on the back‑end, supporting multi‑level menus.

Department Management – configurable organizational hierarchy displayed as a tree table.

Position Management – configure positions for each department.

Dictionary Management – maintain fixed data such as status and gender.

System Logs – record user actions and exceptions for debugging.

SQL Monitoring – Druid‑based database performance monitoring (default admin/123456).

Scheduled Tasks – Quartz integration with task logs.

Code Generation – highly flexible front‑end/back‑end code generation to reduce repetitive work.

Email Tools – send HTML formatted emails.

Qiniu Cloud Storage – sync data without logging into Qiniu.

Alipay Payment – integrated testing account for payment trials.

Service Monitoring – monitor server load.

Operations Management – one‑click application deployment.

Project Structure

The project follows a modular design by functionality:

eladmin-common – common utilities, configurations, custom annotations, aspects, base entities/DTOs, mappers, Redis, Swagger, RSA, and global exception handling.

eladmin-system – core module and application entry point, containing cross‑origin and static resource configuration, data permissions, thread pool, and core functional modules (login, monitoring, scheduling, operations, etc.).

eladmin-logging – logging module for system logs.

eladmin-tools – third‑party tools (image hosting, email, cloud storage, local storage, Alipay).

eladmin-generator – code generation module with templates located in the system module.
