Design and Realization of the Campus Second-hand Musical Instrument Trading Platform Based on Java

The development of Internet technology has provided broader opportunities for resource sharing and resource exchange, and second-hand trading platforms have gradually developed. The second-hand trading platform can realize the sharing of idle items between users, saving resources and costs, and has certain practical value. The front-end users publish their own second-hand musical instruments and purchase other people's second-hand items, and the back-end administrator manages users, commodities and website information. The development of the website mainly uses Java as the main development language, the MySQL database to store data, the MVC mode as the main technical support, and the page technology uses JSP. The transaction of idle items of the secondhand musical instruments by college students on campus has been realized, and the quality and credibility of second-hand musical instruments have been improved.
