Design And Implementation Of Information Resource Network Based On J2ee Framework

The development of software framework is more popular direction in recent years.The framework is a semi-finished products of an application, the framework provides the public structure that can be shared and reusable.The application framework emphasize the reusable design of software and system scalability, to shorten the development cycle of large-scale application software system and improve the quality of development.This paper points out several disadvantages of the widely used EJB framework under J2EE structure. Have proposed a combined framework-SSH by analyzing three popular lightweight opensource frameworks at present: Struts, Spring and Hibernate, provided a flexible and lightweight J2EE solution schema. Then the author introduces the popular EXT framework, propose the combination of SSH framework and EXT framework, analysises how to integrate EXT and Struts2, how to pass data through JSON.The next, this paper analyses the database design, data collection plan, the whole architecture. This paper presents solving the problems left by history data use ETL technology and structure the system based on SOA to ensure the system scalability.Then this paper analyzes the the database design of the knowledge module, and details on how to implement this system using SSH and EXT2.0 framework.Through the combination, we fully bring into play of each advantage of SSH and reduce coupling of each layer and enhance the ability of testing. We also resolve the problem in which the complicated system architecture results in the development of web application system, the including of EXT framework improves user's experience.
