| With the development of the Internet technology and e-commerce, more and more companies try to build their own sales online systems. As a form of e-commerce system, wechat mall system is popular with small and medium-sized enterprises. Wechat mall system gears to needs of all users, thus it can increase the number of potential customers and lead to considerable benefits for the companies.During my internship in Fujitsu, our team received a business that developed a wechat mall system for a company in NanJing. Because of using the traditional business model suffered some losses under the impact of e-commerce, we decided to develope a wechat mall system based on J2EE to improve the situation. The system consists of server side and client side which use the MVC design pattern. On the server side, the system uses the Spring, Mybatis and other advanced technical methods. On the client side, the system uses the FreeMarker, AmazeUI and other technologies to provide a good interaction experience for users.The main achievements of this thesis are summarized as follows. First, after analyzing the requirements of the wechat mall system, which included both functional and non-functional requirements, it found the major functions of the system. Second, it got the architecture design, overall design and detailed design of foreground modules based on the results of the requirements analysis. The architecture design used the J2EE four-tier structure and overall design divided the system into foreground modules and background modules. The foreground system was responsible for processing requests from corporate customers, and background system was responsible for processing requests from administrator. Foreground modules included product module, order module, cart module and address module. Third, according to the detailed design of foreground modules, it discussed implementation of these modules, displayed some flow charts and main code snippets for each function. |
