Based On The Design And Implementation Of J2ee Liaoyou Communication Phs Service Download System

With the rapid telecommunications technology and network development, information exchange and resource sharing on the network playing an increasingly important role. As a remote electronic means of communication, information exchange platform allows users within a certain range in a very inexpensive way to quickly and easily sharing information and documentation resources in order to discuss the form of letters and electronic exchanges. It is no exaggeration to say that information-sharing platform is the best interactive communication link for the Internet users, it is also the soul of the Internet. In the emerging electronic culture, information consulting and business services, information exchange platform also contains a huge market. Such as information exchange platform to provide information notices released district for its enterprise product introduction, promotion, publicity, and service information, companies can market new products faster. We use advanced J2EE to develop Web applications, is also faced with manyissues to consider: how to build user interfaces? Where can we deal with business logic? How to deal with persistent application data? Struts2, Spring, Hibernate WEB based application development of these three open-source framework that can solve these problems for us. How to integrate a WEB application layer and Struts2, Spring, Hibernate technology, display the page as much as possible, business logic and data processing phase separation, to minimize the coupling between each module, thus enhancing system maintainability and scalability, the hierarchy of the system more clear, improve code reuse, easy-to-developer division of labor, give full play to the developer's own expertise, this is the system of one of the issues.Interface provides an effective window of a man-machine dialogue, a good interface not only enables users to apply this system convenient and efficient, but also the image understanding system has a function. In addition, the system requires large amounts of data to support the establishment of a suitable database to store data is very important. On the basis of the needs analysis to determine the proper relationship between the various tables, need to design reasonable and stable data model. These are the systems to be studied and explored.To Design and develop a platform which is for the SCDMA handphone to download resource is the background of this system.This system integrates the Struts2 framework based on MVC model,the ORM mechanisms of Hibernate framework , the persistence of the management of persistent objects,and Spring framework for IoC (Inversion of Control) and AOP (for direction) technology. Presentation layer uses Struts2 framework; business layer uses Spring framework; persistence layer uses Hibernate framework for system development. Finally,we make a detail instruction for how our system runs with specific examples. Finally meet the requirements phase for the system functionality and performance requirements.
