organizationings/community-hospital-276 — reverse-engineered prompt

Build me a flea market management web app based on this project. It should have a Spring Boot backend, a Vue frontend, and use MySQL for the database.

I want regular users to be able to browse second hand items, view item details, post items for sale, edit their own listings, and manage basic account information. There should also be an admin side where staff can manage users, listings, categories, orders or transaction records if they exist in the database, and general site content.

Please make it easy to run locally in IDEA. Use the existing SQL file to set up the database, connect the backend to MySQL, and make sure the Vue pages call the backend correctly. Keep the interface clean and simple with tables, forms, search, pagination, and basic validation. If anything is missing from the README, inspect the existing code and database to infer the intended features. Look up current docs online if needed.
