Narendra0777R/ticketing-system-api ? reverse-engineered prompt

Build me a simple ticketing system API for IT support requests.

I want a Java 17 Spring Boot backend that uses MySQL and Spring Data JPA, with full create, read, update, and delete support for tickets. Each ticket should have a title, description, status, and timestamps, with new tickets starting as OPEN automatically. When a ticket is moved to RESOLVED, it should also save a closed time, and both timestamps should be accurate to the second.

Please expose REST endpoints so I can create a ticket, get all tickets, get one ticket by id, update a ticket status, and delete a ticket. If someone asks for a ticket that does not exist, return a clean 404 response instead of a crash. Keep the app simple and organized, and make sure it runs with Maven. If you need to check current Spring Boot or JPA details online, go ahead and do that.
