摘要
随着Internet的发展，人们的日常生活已经离不开网络。未来人们的生活与工作将变得越来越数字化，网络化和电子化。网上管理，它将是直接管理网络在线考试系统的最新形式。本论文是以构建网络在线考试系统为目标，使用 java技术制作，由管理员和学生两大部分组成。着重论述了系统设计分析，系统主要包括首页、个人中心、学生管理、在线考试管理、试题管理、系统管理、考试管理等功能，以及后台数据库管理。从网站设计到详细实现都根据了网站的建设思想和mysql数据库的设计方法。
该系统的应用可以减少工作人员的劳动强度，提高工作效率与管理水平，具有很大的价值。它可以使网络在线考试系统操作简单，成功率高，使网络在线考试系统的管理向一个更高层次前进。
本系统尝试使用ssm在网上架构一个动态的网络在线考试系统，以使每一用户在家就能通过系统来进行在线考试管理。

Abstract
With the development of Internet, People's Daily life has been inseparable from the Network. In the future, people's life and work will become more and more digital, network and electronic. Online management, it will be the latest form of directly administered online examination system. This paper is to build a network online examination system as the goal, using Java technology to make, by the administrator and students two parts. The system mainly includes home page, personal center, student management, online test management, test questions management, system management, test management and other functions, as well as background database management. From the website design to the detailed implementation are based on the website construction ideas and mysql database design method.
The application of the system can reduce the labor intensity of the staff, improve the work efficiency and management level, has great value. It can make the network online examination system simple operation, high success rate, make the network online examination system management to a higher level.
This system tries to use SSM to construct a dynamic network online examination system, so that each user can manage online examination through the system at home.
