Spring IoC Employee Management System

# Introduction

In this project, you will learn how to build an employee management system using Spring IoC (Inversion of Control) container. The goal is to use the Spring IoC container to extract employee information from a configuration file and store it in a list collection, from which the employee information can be retrieved and printed.
