Struts框架与多种设计模式在网络教学中的应用

采用传统的JSP（JavaServer Pages）方法开发软件系统，存在体系结构差、层间耦合度高和数据传输效率较低等弊端。在详细介绍了MVC（Model—View—Controller）设计模式、Struts框架和DAO（Data Access Object）、VO（Value Object）模式的基础上，研究了如何把DAO、VO设计模式与基于MVC模式的Struts框架结合起来，以实现Struts框架的一种新的分层方式。最后，以教学平台中网上选课系统为应用实例，说明了这种新的分层方式的具体实现方法，此方法明显缩短了软件开发周期，增加了系统可扩展性和可移植性，提高了系统数据传输效率

Using Struts and Design Patterns in Developing a Network Education Platform

Using JSP usually result in that an application system has bad structure,unclear logical assignment and high coupling and lower data transmission efficiency.This paper deals with combining the DAO(Data Access Object) and VO(Value Object) patterns with the Struts framework based on MVC(Model-View-Controller) pattern to implement a new idea of organizing layers of Struts framework.Finally,the implement of a web-based enrolment system as an application example is illustrated,which apparently can reduce the dev...
