The Design And Implementation Of E-commerce Simulation Platform On Java EE Lightweight

With the rapid development of Internet technology, it becomes more and moreobvious that the traditional economic structure is transformed by informationtechnology.Electronic commerce as a global leader in the emerging industries of strategic,is produced under the background of a continuing fusion of traditional economy andinformation technology. The rapid development of electronic commerce bring far-reachinginfluence to the social and economic development. Not only it is changing the traditionalway of production and management of the companies largely, but also is changing people’slife and consumption idea. With the rapid development of electronic commerce industry,the demand for professional in electronic commerce increase dramatically. According topreliminary estimates, the next three years the demand of China’s e-commerce talents isabout4,457,000.In the field of enterprise-level Web application and development, Java EEdevelopment platform which Sun company launched give full consideration to the needs ofa wide range of enterprise development and network application development, thistechnology is becoming more and more mature and becoming the de facto standard fordeveloping application system based on Web gradually. The representative of lightweight framework technologies, such as Struts2, Hibernate and Spring, is designed to eliminatethe complexity of traditional Java EE application programming interface and itsrestrictions. And these frame technologies can simplify the programming model, improvethe responseability of the server and shorten the Web application deployment time as well.In the actual development process, how to select and integrate the frameworks so as toestablish meet the practical needs of open and flexible architecture and make the systemlayers, such as persistence layer, business layer, presentation layer etc, work in a moreloosely coupled mode is the biggest challenge for developers.In this thesis, through the analysis of simulation platform project on the actualdemand of electronic business affairs, we use Struts2framework as the presentation layertechnology, the Hibernate framework as the implementation technique for the persistencelayer, and Spring framework as the control layer technology to fuse Struts2and Hibernate.We mainly discuss how to integrate three lightweight framework technologies——Struts2,Spring and Hibernate tobuild application system with high reliability, openness, scalabilityand fault tolerance. Finally, we strictly abide by the norms of software engineering todevelop the system, complete object-oriented modeling task for the system, and amulti-layer simulant platform of e-commerce based on B/S framwork is ultimatelyachieved by us. The result shows that the whole system development fully meet theexpected design goals, it makes full use of the advantages of lightweight Java EEframework to provide users with the best experiences of the services.
