基于MVC模式的分页组件应用

Application of Paging Component Based on Model-View-Controller Pattern

针对Web数据库系统中的数据分页问题,提出一种基于模型-视图-控制器(MVC)模式的三层分页组件。在数据层中引入Java持久化API和Spring技术,在业务逻辑层中引入泛型DAO模式和桥接模式,在显示层中引入JSP和Struts2标签,并给出部分程序源代码。应用结果表明,与其他分页方法相比,该模型的执行效率较高,稳定性和移植性较好。

Focusing on the question of magnanimous database pagination in Web-based system,this paper proposes a three layers of page component based on Model-View-Controller（MVC） pattern.The implementation includes Java Persistence API（JPA） and Spring as model,GerneticDAO and Bridge pattern as control,JSP and Struts2 tags are applied as view.It presents a short program source codes and the model is proved to be practicable and effective.The practice shows that the page component is easy to reuse,learn and deployment.
