If you are looking for a complete Complaint Management System using Spring Boot + React full-stack final year project that is practical, industry-aligned, and easy to demonstrate in viva, this Complaint Management System is a perfect choice.
This project is built using Spring Boot (Backend), React (Frontend), and MySQL (Database). It allows organizations to manage internal complaints efficiently with role-based access for Employees, Engineers, and HOD (Head of Department).
This project is ideal for BCA, B.Tech, MCA, and MSc IT students.
Project tutorials, coding guides & placement tips for students.
Project Overview
A web-based system where:
- Employees can raise complaints
- Engineers can update complaint status
- HOD can assign tasks and manage engineers
- All users have secure login and role-based dashboard
Tech Stack Used
| Layer | Technology Used |
|---|---|
| Backend | Spring Boot 3.2.3, Java 17+ |
| Frontend | React 19, React Router, Axios |
| Database | MySQL 8.x |
| Styling | Bootstrap 5 + Custom CSS |
| Build Tool | Maven 3.9+ |
Why This Project is NEW and Advanced
This is not a basic CRUD project. It is designed using modern full-stack architecture:
| Traditional College Project | This Project |
|---|---|
| JSP/Servlet only | Spring Boot REST APIs |
| Simple HTML | React SPA (Single Page Application) |
| No role management | Multi-role system (Employee, Engineer, HOD) |
| No real workflow | Task assignment & tracking workflow |
| Static UI | Dynamic React Dashboard |
This makes it closer to real industry systems used in companies.

Viva Questions and Answers
1. Why did you use Spring Boot instead of Servlets?
Spring Boot provides auto-configuration, REST support, dependency management, and production-ready features. It reduces boilerplate code and is widely used in real companies.
2. How does React communicate with Spring Boot?
React uses Axios to send HTTP requests to REST APIs exposed by Spring Boot. The backend processes the request and returns JSON responses.
3. How is role-based access handled?
Each module (Employee, Engineer, HOD) has separate login APIs and dashboard routes. The frontend renders pages based on user role, and backend APIs are separated by role path.
