How to Build a Simple ERP System in Just a Few Hours

Background

A client requested a material‑management ERP system with features for material handling, inbound, outbound, and inventory management. Although the requirements appear simple, the underlying business logic is not trivial.

UI Pages

The following UI screens illustrate the implementation.

Login

Only a single login user is needed; user management is omitted.

Dashboard

The dashboard displays material statistics and lists.

Material Management

Handles adding and managing inventory items to support inbound and outbound operations.

Material List

Shows all material information.

Add Material

Provides a form to add new material records.

Inventory Management

Organizes inventory data, consolidates inbound/outbound records, and performs stock verification.

Inventory List

Enables querying of inventory records.

Inbound Management

Supports inbound operations for materials.

Add Inbound Record

Fills an inbound form to record material receipt.

Inbound List

Filters already inbound materials.

Outbound Management

Handles outbound operations for materials.

Add Outbound

Creates a new outbound record.

Outbound List

Provides statistical listing of outbound materials.

Technology Stack

Vue 3, JDK 17, Spring Boot 3, Spring Security, MySQL, Redis (optional), MyBatis‑Plus.

Tech Stack Introduction

Vue 3 provides responsive data binding and component‑based development; its Composition API improves code maintainability. JDK 17 adds modern Java features such as sealed classes and pattern matching, boosting developer productivity.

Spring Boot 3, built on Spring 6, supports GraalVM native image compilation, significantly reducing startup time and memory usage. Spring Security offers comprehensive authentication and authorization, with OAuth2 and JWT integration.

MySQL stores core relational data. MyBatis‑Plus simplifies CRUD operations with built‑in pagination and code generators, reducing repetitive work. Redis serves as a cache layer to accelerate hot‑data access and supports distributed locking for high‑concurrency scenarios.

Architecture Advantages

The front‑end/back‑end separation uses RESTful APIs; Vue 3 handles UI rendering and user interaction, while Spring Boot delivers robust back‑end services. MyBatis‑Plus’s lambda expressions enable type‑safe SQL construction, avoiding hard‑coded column names.

Spring Security’s filter chain protects API endpoints; role‑based access control ensures system security. JDK 17’s ZGC garbage collector provides low‑latency back‑end performance, and Spring Boot 3’s AOT compilation further optimizes speed.

Development Efficiency

Vue 3’s setup syntax sugar simplifies component logic organization; combined with Vite, it offers lightning‑fast hot module replacement. Spring Boot 3’s auto‑configuration quickly integrates common features, and starter dependencies add middleware with a single import.

MyBatis‑Plus’s ActiveRecord mode allows direct entity operations on the database; the Wrapper condition builder replaces hand‑written SQL. Lombok annotations reduce boilerplate POJOs, keeping the codebase concise.

Summary

Even small requirements reflect the client’s expectations; delivering a complete, polished solution is essential.
