Research And Application Of The J2EE-Based Enterprise Information System Framework

With the rapid development of Internet, call for highly effective developing enterprise application system becomes more and more intense. However, we often faced with below questions in practice: how to builds the development framework of enterprise information system fastly? How to improve the maintainability,reusability,expansibility and security of applications system? How to solves the problems such as data exchange,communion difficulty and data redunance, which due to the heterogeneous system in a enterprise.. Aim at these technique nodus, this thesis researchs and extends some open source frameworks such as Struts,Tiles,Log4j,OSCache,Hibernate and so on, try our best to encapsulate some operation which is independent of business, offers the abstract class of encapsulating common behavior and the logical,canonical programme interface, designs the Enterprise Information System Framework (EISF for short) which is based on MVC pattern.Enterprise Information System Framework provides a series of reusable groupware, such as persistence layer which introduces Dynamic Value Object,Value List Hander and Command pattern, it encapsulates the detail of accessing database and affords the interface of different persistence layer framework; basing on Asynchronous JavaScript and XML (Ajax for short) , we develops the client validity check engine,dynamic cascading menu and common,dynamic tree structure groupware, as well as a set of tag library which include query,pagination,cache an so on. They reduce the code redundancy and predigests the development of interface layer enormously; The security subsystem which is based on Secure Socket Layer (SSL for short) and Role-Based Access Control (RBAC for short) ensures the data security transmission and privilege control. Furthermore, the model of Enterprise Application Integration( EAI for short) which based on Web Services, it supply some helpful explore for the sake of system integration and data communion for the future.The framework predigests developing, furthers the developing efficiency of the Web application system and alleviates the work of the developers to a great extent.Developers may concentrate on realizing of business function. It is adapt to developing large and middle-scale distributed application system. on the basis of this framework, we implemented the Lao Bai Xing medicine Management Information System and some digital campus projects, which has been put in use and got favorable effect.
