Quiz Application Backend

This repository is a learning project focused on exploring Spring Data REST. I built this to understand how to rapidly expose JPA repositories as REST APIs.

A lightweight, efficient backend for a Quiz application built using Spring Boot and Spring Data REST. This implementation focuses on the rapid development of RESTful APIs by automatically exposing JPA repositories.

Key Features

• Rapid API Development: Utilizes Spring Data REST to automatically generate CRUD operations (Create, Read, Update, Delete) and pagination/sorting functionality without boilerplate code.
• Entity Management: Structured data models for Quiz and Question entities with proper relationships.
• Relational Mapping: One-to-Many relationship between Quizzes and Questions.
• Persistence: Configured with MySQL for robust data storage.
• Automated Generation: Uses Lombok to reduce code verbosity for getters and setters.

Tech Stack

• Framework: Spring Boot 3.4
• Language: Java
• Build Tool: Maven
• Database: MySQL
• Data Access: Spring Data JPA & Spring Data REST
• Utilities: Lombok

Project Structure

• Entities:
  • Quiz: Contains fields like title, description, createdDate, and banner.
  • Question: Contains content, options (as a collection), answer, and a link to its parent Quiz.
• Repositories:
  • QuizRepository and QuestionRepository extending JpaRepository to enable automatic REST exposure.

Setup Instructions

1. Database Configuration: Update application.properties with your MySQL database credentials.

   spring.datasource.url=jdbc:mysql://localhost:3306/your_db_name
   spring.datasource.username=your_username
   spring.datasource.password=your_password
   spring.jpa.hibernate.ddl-auto=update

2. Run Application: Start the Spring Boot application.
3. API Usage: - The APIs are automatically exposed under the base path.
   • Standard HTTP methods (GET, POST, PUT, DELETE) are available for /quizzes and /questions endpoints.
   • Relationships can be managed by linking the URI of the parent resource when creating child resources.
