Research Of Web Application Framework Based On The J2EE

Web application framework is an important software reuse technology. It plays an important role when developing web application by improving the reusability, stability and scalability of the system. However, the present existing frameworks can not commendably support coarse granular reusability and sound maneuverability for lacking corresponding mechanism. This thesis describes a new kind of framework(which is named JFSSH in this thesis) as a solution to the above-mentioned problem. This framework is based on Struts,Spring and Hibernate. It provides high level reusability.JFSSH separates and encapsulates the presentation layer,business layer and data persistence laycr,as well as providing preferable support for transaction processing, authentication and authorization. The benefit JFSSH can bring is that its coarse granular characteristic makes it possible to use tools to develop web application, such as web application development platform. It provides a convenient and visual platform for software reuse by using the framework and component technology.Base on the design of JFSSH, the thesis summarizes the presentation layer and data persistence layer's abstract models and description methods, and provides the corresponding user custom interfaces and code generators, which causes the realization of JFSSH application development platform. This development platform makes the web application developer free from heavy low level code programming works and be able to pay more attention to the description of business logic and definition of user interface, which is of great importance to guarantee the good usablility, high efficiency and high reliability of web application system.JFSSH has been used in the project "Plan Management subsystem of Production Management Information System of the Small Medium Enterprise". The practice has proved that JFSSH is applicable for developing large-scale web application by enhancing the efficiency of those complex systems.
