【摘要】：随着经济的发展,科学技术的发展,Internet的发展,人们对互联网越来越重视。WEB也可以被利用来做越来越多的事情,如QQ聊天,淘宝购物,社交网站等。企业对时间的需求越来越紧张。为了满足用户以及企业的需求,在不改变功能以及用户体验感的同时,企业非常有必要进行快速开发。然而web系统在多个领域方面相似度都极其的高。如果这些项目都进行独立开发的话,即浪费时间又浪费资源。并且有可能在规定的时间内不能完成客户的要求与需求。为此,我们设计好地城的框架与架构,是快速开发的必要前提。当然,这些架构必须可以扩展更多跟复杂的项目,从而使开发人员不需要在一次进行底层架构的设计了。本文就是综合使用这些开源框架设计了一个基于J2EE平台可快速开发Web系统的基本架构。该架构采用Struts2提供的MVC分层设计思想,分层设计可以使开发人员分工更加明确,加快开发速度,并且系统问耦合较小,易于维护和扩展。由于是基本架构,因此利于扩展用于快速开发各种Web系统。本文利用Hibernate提供的Java类与数据库关系表的映射关系,封装了底层数据库系统,使程序可以移植到不同的数据库。Spring提供的DAO模块和AOP模块分别简化了数据库操作以及数据库事务。本文对该架构的各个层次进行了详细的设计,并且分析了各个层次之间的联系。为了说明层次间的松耦合,基于该架构设计了一个比较通用的网站系统,该网站系统提供一个后台管理系统和前台展示页面,通过简单的操作可以实现前台页面的所有内容都是动态维护的；且简要介绍了架构和Dorad05的集成,可以实现统一的展现层和快速的响应。最后提出了下一步的工作是基于Acegi开源框架来完善架构的安全机制。
[Abstract]:With the development of economy, the development of science and technology and the development of Internet, people pay more and more attention to the Internet. Web can also be used to do more and more things, such as QQ chat, Taobao shopping, In order to meet the needs of users and enterprises, it is necessary for enterprises to develop quickly without changing their functions and user experience. However, the similarity of web system in many fields is very high. If these projects are developed independently, it is a waste of time and resources, and may not fulfill the requirements and requirements of customers in a specified time. To this end, we design the framework and architecture of Terra City, which is a necessary prerequisite for rapid development. Of course, these architectures must be able to expand more and more complex projects so that developers do not need to design the underlying architecture at once. This paper uses these open source frameworks to design a basic architecture based on J2EE platform for rapid development of Web system. This framework adopts the idea of MVC layering design provided by Struts2, which can make the division of labor among developers more clear. The system is easy to maintain and extend because of its small coupling. Because it is a basic architecture, it is advantageous to extend for the rapid development of various Web systems. In this paper, the mapping relationship between Java classes and database relational tables provided by Hibernate is used. Encapsulated the underlying database system, the program can be transplanted to different database. Spring provided by the DAO module and AOP module to simplify the database operation and database transactions. In this paper, the detailed design of each level of the architecture, and the analysis of the relationship between the different levels. In order to explain the loose coupling between the layers, based on this architecture, a more general website system is designed. The website system provides a background management system and a front display page. Through simple operation, all the contents of the front page can be maintained dynamically, and the integration of the architecture and Dorad05 is briefly introduced. It can realize unified presentation layer and fast response. Finally, it is proposed that the next step is to improve the security mechanism of the architecture based on Acegi open source framework.
