leeyoungkon/bookingservice ? reverse-engineered prompt

Build me a simple booking service that lets users create, view, update, and cancel bookings.

I want it to be a clean Java app that can run locally and also be easy to deploy with Docker and Kubernetes. It should use MySQL for storage, and the basic booking data should include things like customer info, dates or time slots, and status. Make the main flows feel straightforward, with sensible validation and clear error handling if someone tries to book something that is already taken or enters bad data.

Please set it up so I can run it from the command line, and include the pieces needed to bring up the app and the database together. If you need to check current docs for anything, go ahead and look them up online. Keep the code simple, practical, and ready for a real small booking system.
