hamzahraihan/spring-boot-microservice-architecture — reverse-engineered prompt

Build me a simple e commerce style demo app using a Java Spring Boot microservice setup. I want separate services for products, inventory, and orders, plus a single API gateway in front and a basic frontend so I can click around and test the flow.

The app should let me view products, see whether something is in stock, and place an order that checks inventory before it goes through. If an item is out of stock, the order should fail in a clear way. Keep the UI simple but usable, just enough to browse products and submit an order.

Please wire everything together so it can run locally with Docker and feels like a real microservice example, not just isolated services. Add sensible sample data and basic API endpoints for each service. I’d also like a short README with how to start everything and test the main flow. If you need details, look up current docs online and make practical choices.
