## Overview

This repository appears to be a Spring-based commerce API for managing categories, products, orders, and reviews. The principal workflow is an HTTP request routed to a resource controller, handled by its service, and persisted through repositories; product caching is a separate supporting path. The tree and dependencies also indicate database migrations and telemetry integrations. Source excerpts were not provided beyond the build file, so links reflect the module structure and declared dependencies rather than verified method-level calls.

Main entry points: [`src/main/java/com/example/FakeCommerce/services/ProductService.java`](https://github.com/roshan21p/fakecommercespring/blob/main/src/main/java/com/example/FakeCommerce/services/ProductService.java) (Product service), [`src/main/java/com/example/FakeCommerce/controllers/CategoryController.java`](https://github.com/roshan21p/fakecommercespring/blob/main/src/main/java/com/example/FakeCommerce/controllers/CategoryController.java) (Category API), [`src/main/java/com/example/FakeCommerce/controllers/ProductController.java`](https://github.com/roshan21p/fakecommercespring/blob/main/src/main/java/com/example/FakeCommerce/controllers/ProductController.java) (Product API), [`src/main/java/com/example/FakeCommerce/controllers/OrderController.java`](https://github.com/roshan21p/fakecommercespring/blob/main/src/main/java/com/example/FakeCommerce/controllers/OrderController.java) (Order API)
