Tasks Management Application

A comprehensive Tasks Management Application built using Spring Boot and Java, designed to streamline task assignment, tracking, and user management. This project demonstrates the implementation of a robust backend architecture with role-based access control, JWT-based authentication, and RESTful APIs.

Features

• User Management:
  • User registration and login with role-based access (e.g., Admin, User).
  • Secure password handling.
• Task Management:
  • Create, update, delete, and retrieve tasks with priority levels.
  • Assign tasks to specific users.
• Authentication & Security:
  • JWT-based authentication for secure access.
  • Role-based authorization for endpoints.
  • CORS configuration for cross-origin requests.
• Exception Handling: Global exception handling for consistent error responses.
• Validation: Request validation using DTOs and annotations.
• Modular Design: Clear separation of concerns with controllers, services, repositories, and entities.

Tech Stack

• Backend: Spring Boot, Java
• Database: MySQL (or any JPA-compatible database)
• Security: Spring Security, JWT
• Build Tool: Maven

Project Structure

• Controller Layer: Handles HTTP requests and maps them to appropriate services.
• Service Layer: Contains business logic for tasks and user management.
• Repository Layer: Interfaces with the database using Spring Data JPA.
• Entity Layer: Defines the data models for tasks and users.
• Security Layer: Implements authentication and authorization mechanisms.

API Endpoints

Authentication

• POST /api/auth/register: Register a new user.
• POST /api/auth/login: Authenticate a user and generate a JWT token.

Task Management

• GET /api/tasks: Retrieve all tasks.
• POST /api/tasks: Create a new task.
• PUT /api/tasks/{id}: Update an existing task.
• DELETE /api/tasks/{id}: Delete a task.

Prerequisites

• Java 17 or higher
• Maven 3.8+
• MySQL database (or any JPA-compatible database)

Database Schema

Users Table

• id: Primary key
• username: Unique username
• password: Encrypted password
• role: User role (e.g., Admin, User)

Tasks Table

• id: Primary key
• title: Task title
• description: Task description
• priority: Task priority (e.g., HIGH, MEDIUM, LOW)
