Research And Practice Of Struts+Hibernate Framework

J2EE is the most rapidly evolved technology architecture, which has being preferred to develop enterprise-applications.The appearance of the framework of Struts+Hibernate brings the new opportunity to the application of J2EE Web, meanwhile, this framework is still in the stage of trial and improvement.There are a lot of problems to be solved.This thesis focus on key technologies of J2EE Web application based on Struts+Hibernate framework.First the theory of Struts and Hibernate are deeply studied, and then focus on the the production of the research, a teaching-information system is developed as the practice. Based on the research, a series of efficient method of developing J2EE Web application is put forward.The production of the research includes of the following: Hibernate is used to implement Date Persistence; DAO design pattern is used to implement the BusinessDelegate; DTO design pattern should be used to reduce communication load between Web layer and Business layer; Action class should be extended to implement common function such as user login authentication, loading Locale setting etc.; Two classes are created to make applicaton have unified interface; Ajax is used to promote the experience of using the system.According to the practice, above production can evidently reduce coupling between layers and improve reliability, reusability and maintainability of J2EE applications.
