How to Design a Scalable Permission System for SpringBoot E‑Commerce

For backend management systems, permission functionality is essential. This article uses the Mall e‑commerce project as a case study to discuss the design and implementation of a permission system.

Mall Project Overview

The Mall project is an e‑commerce system built with SpringBoot, Vue, and uni‑app, featuring Docker container deployment, multi‑module and microservice architecture, and includes front‑end store and back‑end admin modules covering orders, products, carts, permissions, coupons, members, payments, and more.

Functional Design

Before coding the permission module, the functionality is designed based on existing UI mockups. The permission features are divided into four parts: user management, role management, menu management, and resource management.

User Management

Handles user information and role assignment for users.

Role Management

Manages role information, assigns menus and resources to roles.

Menu Management

Manages menu information.

Resource Management

Manages resource data and resource categories.

Function Organization

After functional design, the features are organized to determine data storage, table structures, and fields, often visualized with a mind‑map.

Database Design

Based on the organized mind‑map, the database tables for the permission module are designed, covering users, roles, menus, resources, and their relationships.

API Design

With the UI mockups as reference, RESTful APIs are defined for each permission feature. For example, the user management API includes endpoints for listing users, creating users, updating user info, and assigning roles.

Technical Highlights

Integrates Spring Security and JWT to provide authentication and authorization.

Uses Spring Security for dynamic permission control of interfaces.

Optimizes permission management performance with Redis and AOP.

Conclusion

Developing a functional module typically involves functional design, organization, database design, and API design, while addressing technical challenges. Mastering this generic design approach makes building similar modules straightforward.
