基于Spring教学辅助系统的设计与实现
摘要：随着网络技术的发展，各种实体服务、应用都开始网络化，同时应用的复杂性不断增加，这对应用所采用的WEB技术提出了更高的要求。
为此,本系统采用了轻量级框架--Spring Framework，通过对它各个模块的分析，深入论述了它的两大特殊机制即控制反转和依赖注入，说明了基于这两个核心机制的Spring框架，适用于大多数Web应用的各种不同要求。并在系统的结构上使用了MVC形式，MVC把系统分为模型(Model),视图(View)和控制Controller)三个层，而后对每个层的实现和关联进行了说明，由于Spring本身具有“无侵入性”的特点, 它又可以方便的集成其他框架。
在此基础上，本文将Spring用于教学辅助系统的开发中，系统主要实现了学生教师的课程查询，学生发表评价、提问，老师查看评价回答问题的功能，并有后台管理功能，可以对课程、用户等所有信息进行管理。并在这个过程中对spring MVC各个模块进行了分析讨论。由于框架的采用，使得整个系统具有良好的层次，也提高了其可维护性和可扩展性。

Design and Implementation of Teaching Assistant System Based on
Spring Framework
Abstract:With the development of network technology, various entities, services,
applications are beginning to network, applications at the same time the increasing complexity of applications using WEB technology has a higher demand.
To this end, the system uses a lightweight framework - the Spring Framework, through the analysis of its various modules into the details of two special mechanism of inversion of control and dependency injection, pointing out that based on these two core mechanisms of the Spring the framework is fully applicable to the general Web applications, most of the functions, structure and performance requirements. The structure of the system to use form of the MVC, the MVC system is divided into three layers model (Model), the view (View) and the control of the Controller) are described, and then each layer to achieve and associated, since Spring itself invasive characteristics, it can easily integrate other frameworks.
On this basis, the Spring for the development of teaching aids, the main achievement of the students and curriculum inquiries, students at the evaluation, ask questions, the teacher read reviews to answer questions, and backstage management function, you can right the course the user all the information management. And the spring of each module in the MVC in this process were analyzed and discussed. The entire system be structured, with good scalability, portability, and maintainability. Keywords: teaching assistant system, MVC, Spring Classification: TP391
