Create GET endpoint for Products

[loiane]

As a customer browsing an e-commerce website or app, I want to see a list of all available products So that I can find items I'm interested in buying.

Acceptance Criteria

1. The API endpoint should return a list of all products in the system.
2. Each product in the list should include at least the following information:
   • Unique product ID
   • Name
   • Description (brief summary)
   • Price
3. The response should be formatted in a standard way, such as JSON.
4. The API should be well-documented so that developers know how to use it.

Additional Considerations

• Error Handling: Define clear error responses for situations like invalid requests or unavailable products.
• Performance: Optimize the API for fast responses, especially when dealing with a large number of products.
• Unique product ID is a number of type Long
• Name is a string of max 100 chars, and min of 3 chars, and it is mandatory and cannot be blank
• description is a string of max 500 chars, and min of 3 chars, and it is optional
• price is of type BigDecimal
• API should have Hibernate validation
• API should have a Controller layer, a Service layer, model and repository.
• API should follow package by domain organization, and not by layer.

Technical Notes

• REST API Design: Use standard HTTP methods (GET) and status codes (200 OK, 400 Bad Request, etc.).
• Data Format: JSON is a common and easy-to-use format for APIs.

Example API Endpoint

GET /api/products

Example Response (JSON)

[
  {
    "id": 12345,
    "name": "Awesome T-Shirt",
    "description": "The most comfortable t-shirt you'll ever wear.",
    "price": 19.99,
  },
  {
    "id": 54321,
    "name": "Stylish Jeans",
    "description": "Classic denim jeans with a modern fit.",
    "price": 49.99,
  },
  // ... more products
]
