** Building a Full-Stack Employee Management System with Spring Boot & REST APIs

In today’s modern software development landscape, building scalable, robust, and efficient backend services is a core skill for any developer. To put theory into practice, I built a complete Employee Management System (EMS) using Spring Boot and Java.

This project demonstrates how to structure a modern Web Application, create RESTful APIs, manage resources, and connect a web user interface to backend services.

*** Project Architecture & Tech Stack

The system follows a standard multi-layer enterprise application architecture, separating concerns between client request handling, business logic, and presentation.

*** Tech Stack Used:

- Backend Framework: Spring Boot (Java 17+)

- API Architecture: RESTful Web Services (@RestController, @GetMapping, @PostMapping)

- Frontend: HTML5, CSS3, JavaScript (Fetch API)

- Build Tool: Apache Maven

- Version Control: Git & GitHub

- IDE: IntelliJ IDEA

*** Key Features

1. Employee Directory Management: View a real-time list of all onboarded employees.

2. RESTful Endpoints: Standardized JSON response endpoints for external client integration.

3. Interactive Frontend UI: A clean, responsive web dashboard serving static assets directly via Spring Boot’s embedded Tomcat server.

4. Dynamic Data Handling: Ability to add, fetch, and organize employee records smoothly.

Implementation

1. Designing the Domain Model (Employee.java)

The core data entity encapsulates basic employee details such as id, name, department, and email.

java

public class Employee {

private Long id;

private String name;

private String department;

private String email;

// Constructors, Getters, and Setters

}

2. Building RESTful Controllers (EmployeeController.java)

The controller exposes HTTP endpoints to allow frontend applications or API clients to perform operations.

@RestController

@RequestMapping("/api/employees")

public class EmployeeController {

@GetMapping

public List<Employee> getAllEmployees() {

// Returns list of employees

}

@PostMapping

public ResponseEntity<Employee> addEmployee(@RequestBody Employee employee) {

// Logic to save employee

}

}

4.Future Goals:

Add a database (MySQL/PostgreSQL) to store data permanently and integrate this project with a complete enterprise web application.
