The Research And Design Of Estate Recommendation Management System Based On Spring Framework

It is a trend to transform the information communication way of modern enterprises and promote their competitive ability through exploring the enterprise application of Web. J2EE has concentrated on the enterprise application since its existence, which contributes a lot to the construction of enterprise application. However, the traditional J2EE framework whose core point is EJB appears cumber to most of SEM's (Small and Media Enterprises) web application and induct certain unnecessary complexity. In addition, EJB's O/R mapping solution—Entity Bean has been proved an unsuccessful technology. In this situation, it is necessary to construct a lightweight Web framework that is equipped with low intrusiveness and able to make the explorer and concrete J2EE platform technology in a coupling state.This paper makes use of the Spring framework originating from open sources and dissects its two key mechanisms—IoC and AOP by analyzing its principle and realization. It also points out that the Spring framework based on these two key mechanisms can be suitable for the majority request of general Web application in the function and performance. Due to its trait of "no intrusiveness", the Spring framework can easily integrate Hibernate to replace Entity Bean's O/R mapping solution and excellent Struts framework.On this basis, this paper puts forward a kind of new Web application framework based on the Spring framework, which integrates Hibernate and Struts. The Web system possesses the following advantages: at first, IoC container based on DI mechanism avoids strong intrusiveness of EJB to business logic layer which makes application of Spring framework eliminate the dependence to concrete container and realize the dynamic configuration of software function;secondly, the framework integrated Hibernate achieves the function of O/R mapping simply, which eliminates the "impedance mismatch" between RDBMS&OOD and improves the performance of data persistence layer;thirdly, it integrates the mature Web layer framework—Struts, which improves the exploring efficiency.Finally, the technology combination of Struts/Spring/ Hibernate is applied to development of estate recommendation system in estate recommendation field and designs the estate recommendation management system in detail. This paper also provides the concrete develop process of estate information management system.
