preface:
With the development of computer network technology in the information age, it has brought great convenience to people. The traditional graduation design process has brought inconvenience to students, teachers and managers to a great extent. For college students, the graduation thesis is a summary of their professional knowledge and skills learned in the school, and for college education, it is the last comprehensive assessment of graduate students. In the whole process of completing the graduation thesis, it needs the close cooperation of students, tutors and personnel. But in reality, the role in a certain link can not keep working for some reasons, which will lead to the stagnation of the completion of the graduation thesis. In order to avoid this situation, in order to facilitate teachers, students and managers to successfully complete the tasks of corresponding roles, colleges and universities need a professional management system for graduation thesis, which integrates all the operations of completing graduation thesis into one system. At the same time, the popularity of various information websites has brought good experience and efficient management to many enterprises or users. Aiming at the development of computer technology in modern colleges and universities, in order to deal with the problems of low efficiency, poor interactivity and heavy workload encountered by college graduates in the process of graduation project management in the past, this system adopts the design idea of software engineering to build a graduation project management system based on java Web suitable for colleges and universities. The system is based on Windows operating system as the service platform, the background database adopts MySQL database, and the server uses Tomcat container and Eclipse development tool to create java language to build service pages. Select functional modules such as graduation project management and performance management and their relationship. The purpose of this graduation project is to use modern network management technology to solve the problems existing in graduation project management, reduce the time for students to choose the topic of graduation project, strengthen the monitoring of graduation project process, and reduce the work intensity of teachers and managers. Using spring MVC framework improves the efficiency of system development, reduces the complexity of the system and makes database access more flexible. Through the test, the application of the system facilitates the communication between teachers and students, strengthens the process management, and facilitates the preservation and display of results.
Functional design:
1. User module management: user login, multi role login, user query and deletion. Users are divided into different permissions and can be flexibly controlled by roles.
2. Tutor management: the administrator can manage and add tutor information after logging in.
3. Student management: administrators and teachers can manage and add student information after logging in.
4. Announcement management: administrators and teachers can manage and add announcements after logging in, and students can view them.
5. Data analysis: after logging in, the administrator can view data analysis and score proportion.
6. Audit topic selection: the administrator can audit, agree or reject after logging in.
7. Thesis management: the administrator can view and download the thesis after logging in
8. Modify data: users can modify their own password.
9. Course management: the teacher uploads the selected courses and checks whether the changed courses pass the selected courses.
10. Release content: the teacher releases the assignment, opening report, demand analysis, database design, etc.
11. Review documents: teachers can review the assignment, opening report, demand analysis and database design.
12. Document management: teachers can view and upload students' thesis documents.
13. Question management: teachers can view and answer students' question information, and students can ask questions
14. Grade management: teachers can manage and view students' grade information.
15. Graduation project management: teachers can review students' papers and view the list of defense qualifications.
16. Progress management: students can check the progress and completion of each document, such as assignment, topic opening, etc.

Paper report:
Summary:
After the recent mastery and study of java object-oriented programming, front-end knowledge and java framework, as well as the development of this graduation project management system during this period, I have better understood the importance of java learning. In developing which system this system is, I have completed a number of experiments and functional tests of the graduation project management platform. During the stage of system development and learning, I realized that I am familiar with java, and then I can independently use relevant technologies. I found that it does have many conveniences, such as java integrates abstraction and encapsulation, inheritance and polymorphism, The functions of code reuse and code expansion are realized, and the speed and efficiency of the overall software development are improved. For example, when the administrator adds a user, it reports java Lang.nullpointexception. Solution: check the console print information, find that relevant information is not filled in when adding, and report to java Lang.nullpointexception, the data item with empty user information found through power-off debugging, the user's complete relevant information must be filled in when saving at the front end, or the database setting field can be empty. The main purpose of learning program design is to improve the key skills and technologies of program solutions to my actual problems.
