The main technical systems were used in the analysis and selection of presentation, the three-tier data processing structure which is based on B/S has been adopted, under the environment of J2EE architecture + Struts framework, the main programming language is Java, database is SQL Server database,server using Tomcat as main project server. Design and development in accordance with the relevant theory of software project management and database design. The running results of the system can be normal use to meet the needs of users, the college teachers and students. This paper introduces in detail the campus second-hand goods trading system development background, needs analysis, hardware and software environment, system design, system detailed design, system code design and post testing and maintenance problems. Design part lists the main project operation diagram, and with the key code of the business logic. The main functions of this system are commodity browsing, product search, product information management, order management, shopping cart management, news management, announcement management, message management, and other functions.
