基于ssm考研助手平台源码和论文
网络的广泛应用给生活带来了十分的便利。所以把考研助手管理与现在网络相结合，利用java技术建设考研助手网站，实现考研助手的信息化。则对于进一步提高考研助手管理发展，丰富考研助手管理经验能起到不少的促进作用。
考研助手网站能够通过互联网得到广泛的、全面的宣传，让尽可能多的用户了解和熟知考研助手网站的便捷高效，不仅为群众提供了服务，而且也推广了自己，让更多的群众了解自己。对于考研助手而言，若拥有自己的系统，通过系统得到更好的管理，同时提升了形象。
本系统设计的现状和趋势，从需求、结构、数据库等方面的设计到系统的实现，分别为管理员，教学秘书和学生的实现。论文的内容从系统的设计、描述、实现、分析、测试方面来表明开发的过程。本系统根据现实情况来选择一种可行的开发方案，借助java编程语言和MySQL数据库等实现系统的全部功能，接下来对系统进行测试，测试系统是否有漏洞和测试用户权限来完善系统，最终系统完成达到相关标准。

Abstract
The wide application of network has brought great convenience to life. Therefore, the management of postgraduate entrance examination assistant is combined with the current network, and the website of postgraduate entrance examination assistant is constructed by using Java technology to realize the informatization of postgraduate entrance examination assistant. It can further improve the management development of postgraduate entrance examination assistant and enrich the management experience of postgraduate entrance examination assistant.
Postgraduate entrance examination assistant website can be widely and comprehensively publicized through the Internet, so that as many users as possible understand and know the convenience and efficiency of postgraduate entrance examination assistant website, not only provide services for the masses, but also promote themselves, so that more people understand themselves. For postgraduate entrance examination assistants, if they have their own system, they can get better management through the system and improve their image.
The present situation and trend of the system design, from the requirements, structure, database and other aspects of the design to the realization of the system, respectively for the realization of administrators, teaching secretary and students. The content of the paper shows the development process from the aspects of system design, description, implementation, analysis and testing. The system according to the reality to choose a feasible development plan, with the help of Java programming language and MySQL database to achieve all the functions of the system, then the system is tested, test whether the system has vulnerabilities and test user permissions to improve the system, the final system to achieve relevant standards.
Keywords: postgraduate entrance examination assistant website Java MySQL database
