This project comes from an e-commerce company, which is mainly to provide convenient service e-commerce platform. In the process of project design and implementation, the author refers to the thought of software engineering. The advanced technology and management methods are adopted on the requirements analysis, preliminary design, detailed design and implementation. Technical architecture uses J2EE development technology which is very popular nowadays. It is combined with Struts2framework. The communication between systems uses the standard HTTP protocol and the transmission of data uses MD5digest algorithm to ensure system scalability, security, and reliability. Electronic purse system has three subsystems, respectively is purse pay subsystem, purse portal subsystem and core account subsystem. Purse pay subsystem provides the payment related functions.
