摘要

随着科学技术的飞速发展，各行各业都在努力与现代先进技术接轨，通过科技手段提高自身的优势；对开放式教学评价管理系统当然也不能排除在外，随着网络技术的不断成熟，带动了开放式开放式教学评价管理系统系统的发展，它彻底改变了过去传统的管理方式，不仅使服务管理难度变低了，还提升了管理的灵活性。这种个性化的平台特别注重交互协调与管理的相互配合，激发了管理人员的创造性与主动性，对开放式开放式教学评价管理系统系统而言非常有利。

本设计的基本思想就是采用SSM框架，以Java为开发语言，MySQL为数据库，使用了Spring、Spring MVC和MyBatis三个框架简称SSM），其中用Spring MVC实现。测试结果表明，该物资管理系统能以一种简便、轻量级的方式实现了物资管理的基本功能，降低了开发的复杂性，提高了系统的可维护性，具有一定的应用价值。

ABSTRACT

With the rapid development of science and technology, all walks of life are trying to connect with modern advanced technology and improve their own advantages through scientific and technological means. With the development of network technology, it has completely changed the traditional management mode, not only reduced the difficulty of service management, but also improved the flexibility of management. This personalized platform pays special attention to the mutual coordination and management, which stimulates the creativity and initiative of the managers, and is very beneficial to the open teaching evaluation management system.

The basic idea of this design is to adopt the SSM framework, take the Java as the development language and the MySQL as the database, and use the Spring、Spring MVC and MyBatis frameworks for short SSM), in which the Spring MVC is used. The test results show that the material management system can realize the basic function of material management in a simple and lightweight way, reduce the complexity of development, improve the maintainability of the system, and have certain application value.

Keywords: teaching evaluation management, JAVA,Mysql
