基于SSH框架的自由交易系统的设计与实现 摘 要 SSH-based Free Trade System Design and Implementation (Department of mathematics physics and information, Donghai Science Technology School 316004) Abstract With the rapid development of the Internet era, E-commerce is not a strange noun any more, and online shopping has been an inseparable part in our daily life. The campus electronic commerce cultural industry which derives from electronic commerce has been more and more popular with university students. However, it’s difficult for students to find buyers, resulting in many books, material, electronic equipment and other student supplies can only be sold cheap to the recycling station, and some even discarded, causing a serious waste of resources. The bazaar, flea market requires a lot of manpower and material resources. Therefore, for the use of these resources, as well as the direct service for students requires a free trading system environment in university campus to realize the free trade among students. The system only manages users and messages, the commodity and the operation of order are completely in the hands of the user management, which can fully realize the purposes of the free trading. As long as the user registered and logged, goods can be sold. The user can place an order goods are being sold under the order, then he can finish the final deal under line. This system is designed and developed under the Struts+Hibernate+Spring frame, using the MyEclipse10.6 development tools and MySQL database. This thesis will make a detailed explanation of the thought that according to the reference software process design process of the system, and make a detailed introduction of the core of the module code, finally tests the completed system. 【Keywords】Free trade system ,Database, Struts frame, Hibernate frame 摘 要 I Abstract II 1绪论 1 1.1课题背景 1 1.2目的和意义 1 1.3系统设计思想 1 1.4系统的开发环境与技术背景 2 1.4.1开发环境 2 1.4.2技术背景 3 2 自由交易系统分析 6 2.1自由交易系统的可行性分析 6 2.1.1市场可行性 6 2.1.2技术可行性 6 2.1.3经济可行性 7 2.2 自
