🏥 Hospital Management System (Spring Core)

A simple Spring Core (Annotation-based) project demonstrating Dependency Injection (DI) and Component Scanning using a Hospital Management scenario.

---

📌 Overview

This project simulates a basic hospital system where:

• A Doctor treats a Patient
• Both are managed inside a Hospital
• Dependencies are injected using Spring Framework (Core)

It’s a beginner-friendly project to understand:

• Spring IoC Container
• Dependency Injection (Setter Injection)
• Component Scanning
• Annotation-based configuration

---

🛠️ Technologies Used

• Java
• Spring Core Framework
• Eclipse IDE (or any Java IDE)
