基于J2EE电子留言系统的设计与实现

传统的电子留言系统将页面,业务和数据混杂在一起,使得系统存在耦合性高,重用性、可维护性、可扩展性差以及Web用户界面响应灵敏性低等缺陷.提出采用Struts框架和Hibernate持久层,设计并实现一个电子留言系统,该系统分离页面逻辑、业务逻辑和数据逻辑,达到结构上松散耦合,提高重用性、可维护性和可扩展性的目的.此留言系统的特点是简洁实用,安全可靠,可维护性强,适用于通用网站.

Design and implementation of Electronics Message System based on J2EE

The traditional Electronic Message System blended the page, the service and the data in the same place. So the System was higher with coupling, bad with recycling, maintainability and extendibility. The interface response sensitive for Web user was lower. The new Electronic Message System was designed and implemented by using Struts and Hibernate. The new System separated the page logic, service logic and data logic, achieved in the structure loose coupling, enhanced the recycling, the maintainability, and the extendibility. This characteristic was succinct practical, reliable, maintainable, and was suitable for common currency website message use.
