Employee Management System

Overview

The Employee Management System is a Spring Boot-based application that provides a RESTful API for managing employee information. It incorporates Spring Security for authentication and authorization, ensuring secure access to various endpoints based on user roles. The project follows a clean and modular architecture, making it easily extensible and maintainable.

Key Features

Security Configuration

Implements Spring Security to control access to API endpoints based on user roles (EMPLOYEE, MANAGER, ADMIN). Provides options for user details management, including in-memory and JDBC configurations.

RESTful API Controller

Utilizes a RESTful API controller (EmployeeRestController) to perform CRUD operations on employee data. The controller supports the following endpoints:

• Retrieve All Employees:

  • Endpoint: GET /api/employees
  • Description: Retrieves a list of all employees.

• Retrieve Employee by ID:

  • Endpoint: GET /api/employees/{employeeId}
  • Description: Retrieves a specific employee by their ID.

• Add New Employee:

  • Endpoint: POST /api/employees
  • Description: Adds a new employee to the system.

• Update Employee:

  • Endpoint: PUT /api/employees
  • Description: Updates an existing employee's information.

• Delete Employee by ID:

  • Endpoint: DELETE /api/employees/{employeeId}
  • Description: Deletes a specific employee by their ID.

Service Layer

Employs a service layer (EmployeeService) to handle business logic related to employee data. The service interacts with a data source (e.g., a database) for CRUD operations.

Exception Handling

Implements exception handling, including a custom EmployeeNotFoundException for scenarios where an employee is not found.

Data Persistence

Utilizes Spring Data JPA for easy and efficient data persistence, allowing interaction with a MySQL database. The data model includes an Employee entity with relevant attributes.

Build and Dependency Management

Configured using Maven, ensuring easy project build and management. Dependencies include Spring Boot Starter modules for web, data JPA, security, and MySQL Connector.
