Employee Management System

This is an Employee Management System built with Java, Spring Boot, and Maven. It provides a RESTful API for managing employee records.

Features

• CRUD operations for employee records
• File-based storage for employee records
• Input validation for data integrity and security
• Design patterns to improve the structure and maintainability of the codebase
• HTTP server to expose the functionality via a REST API

Getting Started

Prerequisites

• Java 17 or higher
• Maven 3.6.3 or higher

Installation

1. Clone the repository

git clone https://github.com/Mosh-K/employee-management-system.git

1. Navigate to the project directory

cd employee-management-system

1. Build the project using Maven

mvn clean install

1. Run the spring boot application

mvn spring-boot:run

Initial Data

Upon starting the server, a few employee records will be automatically created for convenience. These records are stored in the employees directory and can be viewed immediately via a GET request to the /employees endpoint.

Testing

The project includes several unit tests to ensure the functionality of the system. The tests are located in the src/test/java/com/employee directory.

Here are the test files and their locations:

• empSys/controllers/EmployeeControllerTest.java: This file contains tests for the EmployeeController class.
• model/EmployeeTest.java: This file contains tests for the Employee model class.
• storage/FileStorageTest.java: This file contains tests for the FileStorage class.

To run the tests, navigate to the project directory and use the following command:

mvn test

Usage

The application provides the following endpoints:

• GET /employees: Get all employees
• GET /employees/{id}: Get an employee by ID
• POST /employees: Add a new employee
• PUT /employees/{id}: Update an existing employee
• DELETE /employees/{id}: Delete an employee

Employee Format

For the POST /employees and PUT /employees/{id} endpoints, the employee data should be provided in the following format:

{
  "id": "1",
  "name": "John Doe",
  "position": "Engineer",
  "salary": 50000.0
}
