Since the 1920s, computers have appeared crazily in people's lives and work, becoming a good helper for people's lives and work. Computers have penetrated into every household. Online offices and online teaching have replaced the traditional manual record management methods. , using computers to work does not have to be limited to a fixed time and a fixed location, and cross-regional communication can be easily achieved through computer systems. With the popularization of higher education, the number of students has continued to increase. Recently, due to the impact of the epidemic, traditional query and management of student information has become increasingly inconvenient, and manual query management has also reduced work efficiency and increased the number of teachers. and the workload of the school, and it is not convenient for students to make inquiries, so a student information management system was developed.
This system is developed with practical application as the background. Through the system administrator, all students, teachers and other personnel, as well as some courses, grades and other data information related to students can be unified managed to facilitate the retention of data. Teachers and students can register and then log in to the system to query and manage information such as courses, course selections, grades, and school notifications. In general, the front-end of the system is displayed through JSP pages, the back-end uses the SSM framework, and the database uses the currently popular open source relational database MYSQL. This system uses the currently popular vue.js in the front-end technology to make the page display more neat and beautiful.

Since the 1920s, computers have appeared crazily in people's life and work, and become a good helper for people's life and work. Computers have gone deep into every household. Network office and network teaching have replaced the traditional manual record management method. Using computers to work can not be limited to fixed time and location, and cross regional communication can be easily realized through the computer system. With the popularization of higher education, the number of students is also increasing. Recently, due to the impact of the epidemic, the traditional query management of student information is becoming more and more inconvenient, and the manual query management also reduces the work efficiency, increases the workload of teachers and schools, and is not convenient for students to query. Therefore, the student information management system is developed.
This system is developed on the basis of practical application. Through the system administrator, all students, teachers and other personnel as well as some courses and data related to students can be managed uniformly to facilitate the retention of materials. Teachers and students can register and log in to the system to query and manage the information about courses, course selection, grades and school notifications. In general, the foreground of the system is displayed through JSP pages, the background uses the SSM framework, and the database uses the popular open-source relational database MYSQL.

Today, with the rapid economic development in the 21st century, various office auxiliary software has become popular in various industries, such as enterprise ERP software, family financial management software, education student status management software, etc., have been highly praised by users. For education As far as careers are concerned, most schools have developed many web management systems for students and teachers to conduct online learning and management, such as student status systems, examination systems, etc. Through these systems, data maintenance, students and their related information can be conveniently maintained. Information management, and its current application in teaching involves politics, economy, culture and other fields.
Generally speaking, the current education is no longer dominated by the traditional teaching form of a single teacher facing a group of students. Instead, diversified teaching in the form of various auxiliary teaching forms has become the mainstream on the original basis. This kind of The change is precisely because after the computer network is combined with education, it is determined by the many advantages of online teaching in the form of the Internet. The student information management system studied in this topic is mainly based on computer network technology. In terms of student information management, various functions have been designed and implemented. The implemented system has three parts: administrators, teachers and students. It mainly includes three functions: teaching administrator subsystem, teacher subsystem and student subsystem, realizing functions such as student management, teacher management, music management, course selection management, course results, notices and announcements, and student leave requests.
Student information management system is an important part of school business development and is valued by more and more schools. On the one hand, for most schools, the student information management system helps them better query and manage student-related information; on the other hand, students can view courses, course selections, and results online, which will attract more students Use, diversified choices and a completely transparent process in the management process can gain user recognition and increase user stickiness. Through the student information management system, students can complete student-related information queries on the system without going to each teacher's office or academic affairs office to query, enabling users to query student information without leaving home.
This article will design a student information management system for the school based on SSM. According to the concept of user needs as the center, with the goal of meeting user needs in an all-round, high-quality, and efficient manner, it will provide the school with a more powerful student information management system. Incorporating computer information technology into the important technical aspects of the student information management system can not only improve the efficiency of student information management and reduce the workload of administrators, but also make it easier for students to view courses, select courses, check scores, etc., which will contribute to the future development and improvement of the school. The impact is far-reaching. School administrators can manage all information online, and the degree of rationalization of its internal structure directly affects the school administrator's final decision. Therefore, sufficient information and fast and convenient management methods are necessary for a student information management system [1].

After analyzing the background, significance and feasibility of project development, the next step is to discuss the functional division of the project and the design of various tables in the project database during specific implementation. In this chapter, a systematic introduction will be made.
The design of the functional module is to make a system architecture based on the specific functions that the system is to implement and how to divide the functions. It is displayed in the form of a module diagram to facilitate us to list and involve the functions. In terms of system functions, the project is divided into three modules: administrator+teacher+student. Log in to each module to correspond to the corresponding function. The specific function module diagram is shown in Figure 3.1.

通过前面章节的介绍，我们可以看到本学生信息管理系统已经完成了，但是能不能投入使用还是未知，因为在每个项目正式使用之前必须对开发的项目进行测试，如果不进行测试一旦投入使用可能会出现很多未可知的问题，比如使用人数太多导致系统瘫痪，比如某一功能存在bug信息填写错误等等，这些错误将给使用者带来很多的困扰，甚至造成更大的损失，因此测试是项目投入使用的最后一步，为用户提供一个运行顺畅、完美的项目也就是我们进行最后测试的目的。

通过编写学生信息管理系统的测试用例，已经检测完毕用户的登录模块、健康申报信息添加模块、查询课程成绩模块、学生请假添加模块的功能测试，在对以上功能得测试过程中，发现了系统中的很多漏送并进行了完善，经过多人在线进行测试，系统完全可以正常运行，当然在后期的维护中系统将不断完善。
在开发本学生信息管理系统之前我胸有成竹，觉得很简单，但在实际的开发中我发现了自身的很多问题，许多编程思想和方法都还没有掌握牢靠，比如Bootsatrp、Jquery、AJAX 、Spring、SpringMVC、mybeatis等许多Java Web开发技术，通过开发这个学生信息管理系统我成长了很多，懂得了做什么事情都要脚踏实地，不能眼高手低，在本次学生信息管理系统的开发中我逐渐掌握逐渐熟悉的技术。
本次学生信息管理系统的开发中我还学会了例如良好的编程思想和完善的规划思想。在着手编程之前需要罗列出程序框架的大概，脑海中构建出程序的主题框架。做好这一步我们才能胸有成竹的经行开发项目。当设计框架了熟于心之后，需要思考本次编程所需的主要知识点和技术点，并充分学习。如此一来项目的开发才能循序渐进、如丝般顺滑，长久以往就能养成良好的开发习惯。一个程序好不好还要看出的bug多不多，如果在项目完成前做好bug的查验与预防可能发生的事故才能保证程序的稳定长久性运行。如果项目在完工后出现各种问题自己，那么在进入社会后，不仅会给公司团队带来麻烦和增加不必要的工作，还会导致客户流失，公司对自己的评价下降。
在本次项目中我也暴露了诸多问题。对于Java的编程知识有所欠缺，环境配置和算法上出现诸多问题，时常导致项目运行出错，或者目标的实现有问题。或者实现想法时算法未优化，使得代码冗长，程序运行不顺畅。

致谢
至此论文结束，感谢您的阅读。在此我要特别的感谢我的导师，虽然我在实习期间很忙，论文撰写的时候经常是停停改改，但是我的导师依旧十分的负责，时不时的询问我的任务进展情况，跟进我的论文进度，在指导老师的帮助下，我逐步完成了自己的论文和程序，从导师身上也学习到很多知识和经验，这些知识和经验令我受益匪浅。同时我也从导师身上看到了自己的不足，不论是在技术层面上还是在对待工作的态度上，导师如同明镜一般照出了我的缺点我的不足。此外，我还要感谢在我实习期间在论文和程序上帮助过我的同学和社会人士，此前我对于SSM框架方面的一些知识还不了解，是他们在我编写程序过程中给了我很多的启发和感想，也帮助了我对于程序的调试和检测。没有他们我是不能顺利完成本次毕业设计的。至此，我的毕业设计就花上了一个圆满的句号了。
