摘 要

论文从网络教学综合平台的背景和意义开始，阐述了网络教学综合平台的发展趋势，采用MVC设计模式，以JavaEE开发平台技术为基础，提供了基于java的JSP、JavaBean、Struts技术实现组件化的Web程序和B/S三层体系开发的基本思想。从业务需求、模块功能需求等方面，分别对系统中教师、学生、管理员三种角色的体系结构和功能作用进行了分析。从表示层、业务层和数据层三层逻辑层，进行了具体设计和实现。

系统主要实现的效果是教师可以管理课程，如添加某门课程，添加教学大纲、教师计划，还可以实现在线观看视频、发布课后作业等。教师可以查看授课班级学生信息及作业成绩，同时可以发布公告和发布日记。学生可以查看公告、教师信息及课程的相关信息，还可以提交课后作业，对于不懂的问题可以进行网上答疑。管理员可以对教师和学生进行有关操作，同时管理网上答疑模块。通过这个系统，学生可以方便的获取所学课程的学习资料，触发的学习积极性。老师能够在线辅导学生，通过课后作业，了解学生的学习情况。

关键词：网络教学综合平台，JavaEE，MVC设计模式，Struts

Abstract

From the network background and significance of education platform, paper has explain the trends in network education platform, using the MVC design pattern for JavaEE development platform technology, provides a java-based JSP, JavaBean, Struts technology components of the Web programs and B/S three-tier system, developed the basic idea. Demand from the business requirements, functional requirements and other aspects of the module, analysis system structure and function of the teacher, student, and administrator three roles. From the presentation layer, business logic layer and data layer three-layer, the specific design and implementation.

This system to achieve the effect is that teachers can manage courses, such as adding a class, add a syllabus, teaching plan, but also can be achieved online watch videos, publish homework. Teachers can view students of the teaching class information and score, and also can publish the Announcement message and diary. Students can view the Announcement message, teacher information and course information. Students can also submit homework and solve the unknown problems by online Q & A. Administrator can operate teachers and students, and also manages the online Q & A module. Through this system, students can easily obtain the information of the courses, and can be triggered the enthusiasm for study. Teacher can help student on Internet,, and understand students' learning situation by homework which is submitted.
