Gaxown/springboot-inventory-management — reverse-engineered prompt

Build me a simple inventory management app in this Spring Boot project. The README is basically empty, so keep it practical and easy to understand.

I want to be able to manage products, with a name, description, quantity in stock, price, and maybe a simple category. I should be able to add new products, update them, delete them, view a list, open a single product, search by name, and quickly see which items are running low. Make the app store data properly, not just in memory, and include clean validation so bad data does not get saved.

Please wire up the backend cleanly with controllers, services, and database models, and add a simple usable web interface or API responses if that fits the current project best. Add clear run instructions to the README and make sure the project starts with Maven without errors. Look up current Spring Boot docs online if you need to.
