Abstract
In the rapid development of the Internet today, all areas of our life are involved in computer applications, including le Campus second-hand book trading management system network application, in foreign second-hand book trading management system is a very common way, but the domestic management system may still be in its infancy. Le campus second-hand book trading management system has the choice of second-hand book trading management function. Le Campus second-hand book trading management system using Java technology, based on springboot framework, mysql database development, Implements the home page, personal center, user management, user management, books classification management seller, second-hand books management, purchasing books management, purchasing management responses, message feedback management, system management, order management, and other content, this system has good compatibility and adaptability, to provide users with more second-hand book trade information, also provide a good platform, Thus improve the core competitiveness of the system.
This paper first introduces the design background and research purpose, then introduces the system related technology, focuses on the system function analysis and detailed design, and finally summarizes the development experience of the system.
Key words: Java technology; Second-hand book trade; mysql
