Abstract
With the development of high and new technology, computer network has been widely used in various fields. Every industry is undergoing scientific and technological reform. The most important thing is that computers improve the accuracy and efficiency of management. In many colleges and universities, computers have been used to manage various documents. Compared with college graduates like us, a large number of people is the biggest management problem, So it is very important for our school to develop a graduation thesis management system to manage.
It takes a long time for the release of graduation papers to reach students over the years, because it is based on text and the speed of transmission will be very slow. Some staff still complete the manual processing of text, forms and other paper media, and the verification and statistics of document conditions manually, which increases the workload and error rate. The system mainly uses Java technology, All business modules adopt the browser interaction mode, select MySQL as the system database, and select My eclipse as the development tool to design the system. The main function modules of the graduation thesis management system have been basically realized, including administrator, teacher user and student user. Administrator: home page, personal information (personal information, password modification), system user (administrator, teacher user, student user), module management (subject information, topic selection information, task book information, guide book information, first draft information, mid-term test, final draft information, reply information, notice announcement, type management). Student users; Background home page, module management (subject information, topic selection information, assignment information, instruction information, first draft information, mid-term test, final draft information, reply information, notice and announcement). Teacher: background home page, module management (subject information, topic information, task book information, instruction book information, first draft information, mid-term test, final draft information, reply information, notice announcement, etc.), etc.

- Research Background
The graduation thesis management system is an information management system that plays a significant role in higher education units. Its content is crucial to school managers, so the graduation thesis management system should be able to provide users with sufficient information and speed. query means. However, people have always used traditional manual methods to manage graduation thesis-related documents. This management method has many shortcomings, such as low efficiency and poor confidentiality. In addition, over time, a large amount of files and data will be generated, which is difficult for searching, updating and Maintenance has brought many difficulties.
With the continuous improvement of science and technology, computer science has become increasingly mature, and its powerful functions have been deeply understood by people. It has entered various fields of human society and plays an important role. As part of computer applications, using computers to manage student graduation thesis information has advantages that manual management cannot match. For example: fast retrieval, easy search, high reliability, large storage capacity, good confidentiality, low cost, etc. These advantages can greatly improve the efficiency of graduation thesis management, and also make the scientific and formal management of the education department an important condition for integrating with the world.
1.2 Purpose and significance of the research
Graduation thesis occupies a very important position in the talent training plan of colleges and universities. It is a comprehensive test of students' four-year learning achievements, innovation ability and comprehensive quality, and it is also a comprehensive inspection of teachers' four-year teaching quality. Therefore, graduation thesis is an important part of undergraduate teaching in colleges and universities, and it is an important way to comprehensively examine students' knowledge ability and standardized writing. Graduation thesis occupies a very important position in the talent training plan of colleges and universities. It is a comprehensive examination of students' four-year learning achievements, innovation ability and comprehensive quality, and it is also a comprehensive examination of teachers' four-year teaching quality. Therefore, graduation thesis management has accordingly become an important task in colleges and universities. Traditional graduation thesis guidance involves point-to-point communication between teachers and students. There is no suitable communication platform, from topic formulation to topic selection, to students completing the entire graduation project. The process requires teaching administrators, teachers, and students to invest a lot of energy. There is a lack of electronic and networked offices, and information communication between teachers and students is not smooth. Submission of electronic papers still requires e-mail and other means, which is very troublesome for students. The progress is also difficult to control and understand, and the submission and announcement of results also require manual input by teachers. In response to the above problems, this design intends to implement a general graduation thesis management system to achieve scientific and informatization of graduation thesis management, so that all aspects of teaching work are in a "visual" controllable state, problems can be discovered in a timely manner, and the quality of graduation thesis can be improved. . Make communication between teachers and students more convenient and faster.
1.3 Development status
With the continuous advancement of Internet technology, the world has entered the "Internet +" era, and the education industry is also undergoing earth-shaking changes driven by the wave of Internet innovation. Universities at home and abroad have begun to integrate their teaching and management work with computers. The combination of Internet technology can improve the quality of education and teaching efficiency. At present, almost all universities in China have their own academic management systems to manage students' academic records, but there are very few units that rely on digital information management for graduation thesis management. At present, foreign research work in this area started relatively early. In the last century, the United States established the National Science Foundation Network. The information of fund applicants is uniformly stored in the National Science Foundation Network, which provides applicants with unified network information management services. These services include online project application, project review, project control, etc. At the same time, various colleges and universities in North America have established relevant academic management systems. Students can log in to the system through the Internet to write and submit papers. It also provides a communication message mechanism to communicate with their teachers online about paper revisions, and can conduct real-time online communication. It can be seen that the supervision and management of the paper writing process is a popular research direction abroad, and the combination of technology and practice is more reasonable. The University of Nottingham once developed a graduation thesis management system, which also provided the function of supervising the thesis writing process and provided a teacher-student communication platform on which students can communicate with their instructors during the completion of the thesis. This system has achieved student success Good reviews from teachers. Although the teaching system and management system at home and abroad are very different from those of domestic universities, it has indeed inspired us on how to improve the efficiency of paper management and improve the accuracy of work. In China, Nankai University has designed and developed a Web-based graduation project management system, which manages all aspects from thesis topic selection to graduation project score entry, and provides teacher-student interaction functions on the Web.": Southwestern University of Finance and Economics Paper The management system mainly implements the paper upload function and teacher approval function. Teachers' review of papers is completed on this system. The submission of students' papers and teachers' paper review work are unified on this system. Graduates from Wuhan University of Science and Technology The thesis management system supervises the students' graduation project process, and also incorporates thesis defense and thesis recommendation into the system. It can be seen that each school will have a focused design and development system based on the actual situation of the school's teaching management. However, each system mentioned so far has some shortcomings. For example, redundant system page information leads to poor system user experience, data security guarantee needs to be improved, low browser compatibility limits system promotion, etc.
To sum up, it is necessary to develop a set of teaching methods suitable for the unit based on its own teaching work environment and rules and regulations.
A thesis management system used by students and teachers is very necessary. The system provides unified information management for the unit's graduation thesis. The system also provides teacher review, college review, and thesis review management functions. It provides students with functions such as uploading papers, viewing review opinions, and obtaining thesis review progress. This has greatly improved the school's work efficiency and quality.
The front-end framework of this system uses the popular progressive JavaScript framework Vue.js. Use Vue-Router and Vuex to realize dynamic routing and global state management, Ajax to realize front-end and back-end communication, and Element UI component library to quickly prototype the page. Back-end part: Use springboot as the development framework, and integrate MyBatis, Redis and other related technologies.

- MVVM pattern
MVVM is the abbreviation of Model-View-ViewModel. It is essentially an improved version of MVC. MVVM abstracts the state and behavior of the View, allowing us to separate the view UI and business logic. Of course, ViewModel has already done these things for us. It can take out the data of the Model and help handle the business logic involved in the View due to the need to display content. Microsoft's WPF brings new technical experiences, such as Silverlight, audio , video , 3D , animation ..., which results in the software UI layer being more detailed and customizable. At the same time, at the technical level, WPF also brings new features such as Binding, Dependency Property, Routed Events, Command, DataTemplate, ControlTemplate and so on. The origin of the MVVM (Model-View-ViewModel) framework is a new architectural framework that evolved from the application method of combining the MVP (Model-View-Presenter) pattern with WPF . It is based on the original MVP framework and incorporates the new features of WPF to cope with increasingly complex changes in customer needs.

- Mysql database
The advancement of science and technology has brought many conveniences to daily life: classroom projectors use virtual imaging technology, and digital cameras use photoelectric detection technology. For example, the records of supermarket goods entering and leaving the warehouse require an information warehouse. This information warehouse is a database, and this graduation thesis management system also needs the support of this technology.
The software MySQL is used because it can accept access from multiple users, and Archive etc. exist in it. It will first classify the data and then save it in tables respectively. Such special operations will improve the speed of the data management system itself and allow the database to be used flexibly. MySQL's code is public and allows others to compile and upgrade it again. This feature can reduce user costs and form a good website system when paired with appropriate software. Although it has shortcomings, in all aspects, it is the mainstream application object of users.
B/S (Browser/Server) is a more trouble-free architecture than its predecessor. It uses Web server to complete data transmission and exchange. You only need to download the browser as the client, and then the work will be "downsized", and there is no need to consider the problem of constantly installing software [9].

- Introduction to spring boot framework
The Spring framework is an open source application framework on the Java platform that provides a container with control inversion characteristics. Although the Spring framework itself has no restrictions on the programming model, its frequent use in Java applications made it so popular that it was later used as a supplement or even a substitute for the EJB (Enterprise JavaBeans) model. The Spring framework provides a series of solutions for development, such as utilizing the core features of inversion of control and implementing inversion of control through dependency injection to implement containerization of the managed object life cycle, using aspect-oriented programming for declarative transaction management, and integration A variety of persistence technologies manage data access, provide a large number of excellent web frameworks to facilitate development, and so on. The Spring framework has the Inversion of Control (IOC) feature. IOC is designed to facilitate project maintenance and testing. It provides a method for unified configuration and management of Java objects through Java's reflection mechanism. The Spring framework uses containers to manage the life cycle of objects. The container can configure objects by scanning XML files or specific Java annotations on classes. Developers can obtain objects through dependency lookup or dependency injection. The Spring framework has an aspect-oriented programming (AOP) framework. The Spring AOP framework is based on the proxy mode and is configurable at runtime; the AOP framework mainly modularizes cross-concerns between modules. The AOP framework of the Spring framework only provides basic AOP features. Although it cannot be compared with the AspectJ framework, it can also meet basic needs through integration with AspectJ. Transaction management, remote access and other functions under the Spring framework can be realized by using Spring AOP technology. Spring's transaction management framework brings an abstraction mechanism to the Java platform that enables local and global transactions, as well as nested transactions, to work with savepoints and in almost any environment on the Java platform. Spring integrates a variety of transaction templates. The system can configure transactions through transaction templates, XML or Java annotations, and the transaction framework integrates functions such as messaging and caching. Spring's data access framework solves common difficulties developers encounter when using databases in their applications. It not only provides support for all popular data access frameworks such as Java: JDBC, iBATS/MyBATIs, Hibernate, Java Data Objects (JDO), ApacheOJB and ApacheCayne, but can also be used with Spring's transaction management to provide data access. Flexible abstraction. The Spring framework did not initially intend to build its own Web MVC framework . During the development process, its developers believed that the separation between the presentation layer and the request processing layer of the existing StrutsWeb framework, as well as between the request processing layer and the model, was not enough, so they created SpringMVC.

- Vue.js main functions
Vue.js is a progressive framework for building user interfaces. Unlike other heavyweight frameworks, Vue adopts a bottom-up incremental development design. Vue's core library only focuses on the view layer, and is very easy to learn and integrate with other libraries or existing projects. Vue, on the other hand, is fully capable of driving complex single-page applications developed using single-file components and libraries supported by the Vue ecosystem.
The goal of Vue.js is to implement responsive data binding and composed view components through the simplest possible API.
Vue.js itself is not a full-featured framework - it only focuses on the view layer. Therefore it is very easy to learn and very easy to integrate with other libraries or existing projects. On the other hand, Vue.js can also power complex single-page applications when used with related tools and supporting libraries.
The development environment and configuration of the system can be installed by yourself. The system is developed using the springboot framework, and the relatively mature Mysql database is used to interact with relevant data between the system's front-end and back-end. The database is modified and maintained according to technical language and needs. It can make the system operation more stable and safe, thereby completing the development of the system.

- Technical feasibility analysis
-
The so-called technical feasibility refers to whether the functions planned in the early stage can be satisfied within a limited time. Will you encounter problems that cannot be solved in development and design? Whether the completed project can be used well, and if there are shortcomings, will it be very difficult to maintain in the later period? After evaluating the system, it was determined that existing technology could achieve the goals. Using Java technology to implement dynamic pages, embedding low-dependency design patterns, flexible databases, and stable servers, the operating efficiency of the entire system is greatly improved. It can be seen from this that achieving the goal at the technical level is not an unreasonable idea.
Most of the tools used in the project are currently popular open source and free, so in the early stage of development, the funds used for the project will be greatly reduced, and the development of the software will not be affected by funds during the project startup period, so It is still economically feasible. Try to meet the needs of users with the least amount of money. Save money on labor costs and equipment costs. We will go further and further on the road of paperlessness and high efficiency.
The operation of realizing the functions of this system is very simple. Common configurations of ordinary computers can run this software, and as long as you have basic knowledge of computer use, you can use this software smoothly. The computer has the ability to connect to the Internet and can access the system normally. The operator does not need to have any superb abilities. He only needs to understand the business process and perform correct operations according to professional knowledge. Therefore, the graduation thesis management system is operationally feasible.
Before system development and design, you should make a preliminary idea about the functions, clearly understand what sections the management system has, what functions each section has, whether the overall design meets the needs of users, and then conduct a detailed analysis and summary of the developed system functions. , thereby designing a complete system and implementing it. Communication analysis between users and developers to achieve the best level of understanding and optimize system functionality.
The student user backend function diagram is shown below.
Figure 3-1 Student user backend function diagram
The administrator backend function diagram is shown below.
Figure 3-2 Administrator use case diagram
The teacher backend function diagram is as follows:
Figure 3-3 Teacher use case diagram
After analyzing the requirements of the graduation thesis management system, the entire system is mainly divided into three parts: administrators, teachers, and student users. The branch functions under each module are different. The function is explained as follows:
Student User Module:
( 1 ) Student user registration and login: Visitors can enter the system at any time and browse the information in the system, but if they want to implement operations such as book information and message boards , they must have an account in this system. If they do not have an account, they can register To perform related operations in the future, users can also control personal information and operation information through the " Personal Account " button.
(2) Topic information : You can view " topic information" under "topic information ", edit the topic information and submit it, waiting for the teacher's review and reply ;
(3) Personal information: When the user clicks the "My" button in the upper right corner, he will enter the corresponding backend to manage personal information;
( 4 ) Assignment information : In the " Assignment information " menu, after we click to enter, we can edit the content of the assignment and submit it, waiting for the teacher's review and reply ;
( 5 ) Instruction information : In the " Instruction information " menu, after we click to enter, we can edit the details of the instruction and upload the contents of the instruction for submission, waiting for the teacher's review and reply ;
(6) First draft information : In the " First draft information " menu, after we click to enter, we can edit the details of the first draft of the paper and submit it, waiting for the teacher's review and reply ;
(7) Mid-term inspection: In the " Mid-term inspection " menu, after we click to enter, we can upload the inspection documents for submission and wait for the teacher's review and reply ;
(8) Final information: In the " Instruction Information " menu, after we click to enter, we can upload the final document for submission and wait for the teacher's review and reply ;
(9) Defense information: In the " Defense Information " menu, after we click to enter, we can edit the details of the defense and submit it, waiting for the teacher's review and reply ;
(10) Notifications and Announcements: In the " Notifications and Announcements " menu, after we click to enter, we can view the announcement information released by the administrator ;
Administrator module:
(1) Login: The administrator's account is directly set in the data table and does not require registration;
(2) System User Management : When you click the " System User Management " menu, three submenus will appear: Administrator + Teacher + Student User , and you can add, delete, modify and check these three
(3) Notification and announcement management,Administrators can add, publish, query and delete public information.
(4) Module management: When you click the "Module Management" menu, topic information + topic selection information + task book information + instruction book information + first draft information + mid-term inspection + final draft information + defense information + type management will appear. These nine submenus can add, delete, modify and check the nine modules.
Teacher module:
- Login: The teacher 's account is directly set in the data table and does not require registration;
- Personal information: When the user clicks the "Teacher" button in the upper right corner, they will enter the corresponding backend to manage personal information;
( 3) Module management: When you click the "Module Management" menu, eight sub-sections will appear: topic information + topic selection information + task book information + instruction book information + first draft information + mid-term inspection + final draft information + defense information Menu, you can perform operations such as review and reply to these eight modules.
Non-functional requirements analysis
There are many non-functional requirements for the system, such as performance requirements, maximum number of users that can be hosted, stability, ease of use, etc. This system analysis takes into account the need for ease of use. Because the system is for people to use, it must be fully considered from the user's perspective and the user experience to make the system easy to understand, easy to use and easy to operate.
The zero-layer data flow chart includes modules such as login, user functions, and retrieval and maintenance. The data storage used in the login module includes user account documents. The storage required by the user function module is the data documents of each user function module. Retrieval and maintenance use the above. Data documents are retrieved by keywords.
The zero-layer data flow diagram of the system is shown in the figure below.
Figure 3-2 System data flow diagram (zero layer)
The one-level data flow chart is a refinement of the zero-level data flow chart. Login is subdivided into filling in login data and improving data, and user functions are subdivided into basic user functions and main user functions.
The one-level data flow diagram of the system is shown in the figure below.
Figure 3-3 System data flow diagram (one layer)
At present, the main data access method of the B/S system is: users can enter the system through the browser page, and the system can automatically process the requests sent by the users to the server. The processing of the requests is carried out in the background of the system. By performing corresponding operations on the page, you can see the processing results delivered by the server. The graduation thesis management system is mainly divided into a three-layer architecture design of view-model-control. In the view layer, it mainly operates the data that is fed back and displayed on the server side to the client. In the model layer, it mainly handles related business logic, data integration, etc. The final control layer is between the view and the model, mainly It is to adjust the relationship between the two layers and finally implement the transmission of data.
The system architecture diagram is shown in the figure below.
Figure 4-1 System architecture diagram
The purpose of system design is to analyze all functional structures included in the system and prepare developers for the design, development and implementation of the system. After preliminary demand investigation, analysis and sorting, the overall demand determined mainly includes multiple modules, namely: backend: homepage, personal information (personal information, password modification), system users (administrators, teacher users, student users) , Module management (topic information, topic selection information, task book information, instruction book information, first draft information, mid-term inspection, final draft information, defense information, notices and announcements, type management). The overall role of the system is divided into three parts, one is the student user, the other is the administrator, and the third is the teacher. The system functional structure diagram is shown in the figure below.
Figure 4-2 System functional structure diagram
For a system to be developed, ER diagrams can allow others to understand the transactions of the system and the relationships between them faster and easier. According to the conclusions drawn in the system analysis stage, it is determined that there are multiple entities in the graduation thesis management system, including travel registration, student vaccination appointment, leave, diary, students, and teachers.
The overall ER diagram of the system is shown in the figure below.
Figure 4-4 Overall system ER diagram
The logical structure of the database is to describe the ER diagram using specific fields in the database. Use field and data type descriptions to materialize object characteristics, and finally form a database table structure with certain logical relationships. Some of the data structures required by the graduation thesis management system are shown in the following table.

系统的登录窗口是用户的入口，用户只有在登录成功后才可以进入访问。通过在登录提交表单，后台处理判断是否为合法用户，进行页面跳转，进入系统中去。
登录合法性判断过程：用户输入账号和密码后，系统首先确定输入输入数据合法性，然后在login.jsp页面发送登录请求，调用src下的mainctrl类的dopost方法来验证。
用户登录模块的IPO如下所示：
输入：用户名和密码。
处理：
1）检测用户输入的账号、密码是否正确及在数据库已对应存在。
2）从数据库中提取记录，并储存在本地的session中（timeout默认=30min）。
3）根据用户名，将其显示在系统首页上。
输出：是否成功的信息。
登录流程图如下所示。

经过对此系统的测试，得出该系统足以满足用户日常需求，在功能项目和操作等方面也能满足操作员对于其他用户的管理。但是，还有很多功能有待添加，这个系统仅能满足大部分的需求，还需要对此系统的功能更进一步的完善，这样使用起来才能更加的完美。
通过这次毕业论文管理系统 的开发，我参考了很多相关系统的例子，取长补短，吸取了其他系统的长处，逐步对该系统进行了完善，但是该系统还是有很多的不足之处，有待以后进一步学习。
实践证明，毕业论文管理系统有着非常好的发展前景，经过测试运行，系统各项功能都十分完善，界面简洁，使用方便，操作容易，在技术理论上已经成熟。
通过毕业论文管理系统的开发，本人巩固了之前学过的知识，如今将平时所学到的知识融合在设计中，在设计过程中，做了很多的准备，首先，在数据库系统的设计过程中，尤其是在数据库的工作原理、工作特点，对其深刻的讨论，与此同时，对于小型站点来说，最好服务器的选择，其次，利用所学的知识点分析所做的系统，并在此基础上设计。
At present, this system has been online and is in the trial operation stage. User feedback has been good and it has basically fulfilled user needs. No blocking problems occurred during the trial operation. Some shortcomings and minor problems have been corrected in time. After the system is online, in order to ensure data To ensure the security, the system is backed up once every two months, and the database backup is done once a week. The system is deployed in a rented cloud platform server.
After the successful launch of this system, it has been highly recognized by users, but further research and processing are needed in terms of function and performance to make it have higher performance and better user experience.
In the future upgrade process of the system, it is necessary to solve a series of problems raised by users, such as how to avoid browser compatibility issues during the printing process, how to maintain a high response speed when a large number of users visit, and how to maintain a high response speed during the future upgrade process of the system. The Lieutenant General will focus on resolving these security issues.

Acknowledgments
Time flies so fast, and in the blink of an eye, my four years of study in college are coming to an end. Whether it is in these four years of study or life, the teachers have given me a lot of help, which has benefited me a lot throughout my life. The teachers not only helped me establish a correct outlook on life and values, but also helped me develop many good habits and establish a sense of lifelong learning. Here, I would like to express my heartfelt thanks to all my teachers. At the same time, I would also like to thank my partners who have grown up with me during these four years. They gave me selfless help and care, and allowed me to gain many sincere friendships during the best four years of my life.
The graduation project is the last answer to the four years of university, and we are busy with the wonderful ending of these four years. In the early stages of choosing a topic for my graduation project, I was very nervous and worried that the topic I chose would be complex and difficult to understand, and I felt that my failure to do so would affect my graduation. It was the instructor who provided us with the theme and specific requirements for the graduation project. He asked us not to be too vague about the graduation project. If we had any objections to the theme, we should communicate with him in time. He also helped us introduce outstanding students he had taught. Sister, please guide us so that the problems encountered in redesign can be solved in time and provide good guidance conditions for us to complete our graduation project.
The graduation design project is mainly a comprehensive test of the professional knowledge I learned in college, so that we can truly apply the technical knowledge we have learned to actual hands-on development. Through the development of the project, I realized many aspects of myself. Inadequacy, the knowledge learned is not solid, and the knowledge learned cannot be well applied to the actual development of the system. Later, by consulting a large number of books in the library, completing a systematic design outline, reading notes and translating, the graduation project not only tested our personal abilities, but also tested our learning attitude and attention to detail. I am very grateful to my instructor for his help, which enabled me to successfully complete my graduation project.
Finally, I would like to thank my classmates for your constant help, encouragement, staying up late, maintaining debugging, testing the program, and finally completing the operation of the wedding management system. The time we are communicating and talking about will be our future wealth, and I want to thank you deeply.
Graduation is around the corner. In my future work and life, I will remember the teachings of my teachers and the help of my classmates, and continue to work tirelessly and pursue my goals to repay everyone who has supported and helped me!
