Visitor Management System - Backend

📌 Overview

This backend powers the Visitor Management System, providing secure authentication, visitor approvals, and real-time tracking. Built with Spring Boot, it follows Microservices Architecture with API Gateway, Eureka Server, and RBAC (Role-Based Access Control) for scalability and security.

🚀 Features

• 🔐 Secure Authentication & RBAC
  • Admins can approve/reject visitors.
  • Visitors can check their approval status.
• ⚡ Microservices-Based Architecture
  • API Gateway for efficient request handling.
  • Eureka Server for service discovery.
  • Load Balancer for distributing traffic.
• 🔍 Real-Time Monitoring & Error Handling
  • Eureka Server for service health checks.
  • Global Exception Handling for debugging.
• 📍 Smart Visitor Registration & Tracking
