Spring Boot Project Generator

A React-based intelligent Spring Boot project generator that creates complete, production-ready Spring Boot applications based on API purposes and requirements.

🚀 Features

• Intelligent API Generation: Select from predefined API purposes (User Management, Product Catalog, Order Management, etc.) and the system generates appropriate code
• Smart Integration: Automatically understands API relationships and generates integrated code that works seamlessly together
• Purpose-Driven Development: Instead of writing boilerplate code, describe what your API should do and let the generator handle the implementation
• Complete Project Structure: Generates Maven project with proper dependencies, configuration, and folder structure
• No Database Required: Uses H2 in-memory database for development, making it easy to get started
• Download Ready: Generates a complete ZIP file with your Spring Boot project ready to run

🎯 Supported API Types

User Management

• Registration and authentication
• Profile management
• Role-based access control
• Generated: User entity, authentication endpoints, security configuration

Product Catalog

• Product CRUD operations
• Category management
• Inventory tracking
• Generated: Product entity, catalog endpoints, validation

Order Management

• Order creation and tracking
• Status management
• Customer integration
• Generated: Order entity, order processing endpoints, status workflows

Content Management

• Article/blog management
• Publishing workflows
• Author management
• Generated: Content entity, publishing endpoints, metadata handling

Notification System

• Multi-channel notifications
• Read/unread status
• User targeting
• Generated: Notification entity, delivery endpoints, status tracking

File Management

• File upload and storage
• Metadata management
• Access control
• Generated: File entity, upload endpoints, storage configuration

🛠️ How It Works

Step 1: Project Configuration

• Enter project name, group ID, package structure
• Select Java version (11, 17, or 21)
• Auto-generates Maven coordinates

Step 2: API Builder

• Click "Add New API" to open the purpose-based builder
• Select the purpose that best matches your needs
• Customize endpoints, fields, and descriptions
• Add multiple APIs - the system will integrate them intelligently

Step 3: Code Generation & Download

• Review the generated project structure
• Preview individual files (POM, entities, controllers, services)
• Download complete ZIP file with your Spring Boot project

🔄 Example Workflow

Let's say you want to build an e-commerce backend:

1. Project Setup: Name it "E-commerce API", set package as com.example.ecommerce
2. Add User Management API: For customer registration and authentication
3. Add Product Catalog API: For managing products and categories
4. Add Order Management API: For handling customer orders
5. Generate: The system automatically:
   • Links users to orders
   • Links products to order items
   • Adds security configuration
   • Creates proper database relationships
   • Generates integrated endpoints

Result: A complete e-commerce backend with user auth, product management, and order processing!
