description	Focuses on Spring Boot business logic, REST API design, and database integration. Use when implementing controllers, services, or repository logic.

Backend

Overview

This skill transforms Gemini CLI into a senior Java developer for the FastFood project. It focuses on writing robust business logic, designing RESTful APIs, and optimizing database performance within the Spring Boot ecosystem.

Guidelines

1. Spring Boot Layers

• Controllers: Handle HTTP requests, map them to service calls, and return the appropriate response (view or JSON).
• Services: Contain all the core business logic, including validations and data processing.
• Repositories: Define the database access layer using Spring Data JPA.

2. API Design

• REST Principles: Follow RESTful conventions (GET, POST, PUT, DELETE) and use appropriate status codes.
• Endpoints: Standardized endpoints like /{entity}/all, /{entity}/{id}, and /{entity}/count.

3. Database & Transactions

• Transactional Support: Use @Transactional for service methods that involve multiple database operations.
• Querying: Use JPQL or native queries only when basic Spring Data JPA methods are insufficient.

Workflow

1. Analysis: Determine the required business logic and data model changes.
2. Implementation: Build the Controller, Service, and Repository components.
3. Integration: Connect the backend with the frontend via model attributes.
4. Validation: Test the API logic through unit tests and integration tests.
