Near the end of the semester, or graduation project, you are still doing java program, network programming and final homework. Do you think the teacher's homework requirements are big? I don't know what to do with my graduation project? Are there too many web features? No suitable type or system? wait. Here, you want to solve the problem in this column 👇🏻👇🏻👇🏻👇🏻
java project boutique actual case sharing
Web front end final homework web page practice
Can meet your needs. The original Jsp, SSM, SpringBoot, HTML+CSS+JS page design, web college students' web design homework source code and so on can be solved by reference. Without much to say, take an online student course selection system as an example
Introduction to preface:
Our university was upgraded to an undergraduate university after the merger of three colleges and universities. Weifang art school was merged in a few years ago. Therefore, the level of students is stepped and the training mode is diversified. Therefore, as one of the core work of higher education and teaching, the workload of course selection and course scheduling is bound to increase exponentially. Obviously, the traditional way of course selection and arrangement can not adapt to the current special educational situation of our school. It is urgent to design a campus course selection management system to improve its work efficiency. At present, our university has 22 teaching units, 68 undergraduate majors and nearly 23000 full-time students. The campus course selection management system fully integrates the technology and concept of CRMc2] into the campus information system, so that all teachers and students can take the convenience of the campus management system for scientific research and learning, and well solves the problems of difficult course selection of students and heavy workload of teachers in the past. Compared with the traditional way of course selection, the course selection management system based on Java uses computers instead of manpower to closely connect school managers, teachers and students, so as to achieve the efficient exchange of information. With this course selection system, the school's educational administration managers can make the teaching resources can be allocated and used quickly and reasonably, so as to minimize the waste of resources; Teachers and course selection managers can greatly improve their work efficiency, so that they have more time and energy to focus on their own work; Students ensure timeliness and accuracy in online course selection, so as to avoid the failure and delay of course selection caused by uncertain factors such as repetition and congestion. It fully embodies the advantages of systematic management in this information age.
Main function design:
Operating environment: java jdk 1.8 and mysql5 are preferred , Tomcat 7. X, 8. X and 9. X versions are available
Main technologies: HTML+CSS+JavaScript+jsp+mysql
Main character design:
1. Administrator: administrator login, student management, teacher management, class management, add class, add teacher, add student, course management, add course, system user management, add user, modify password and other functions.
2. Teachers: Teacher login, course selection management, adding course selection students, score management, adding scores, viewing student information, viewing class information, viewing personal files, modifying passwords and other functions.
3. Student: student login, course selection management, score view, view personal file, change password and other functions
Screenshot of main functions:
User login:
Enter the account password, select the user role to log in, and each role corresponds to different function permissions
Administrator homepage:
After the administrator logs in, the main function modules include: student management, teacher management, class management, add class, add teacher, add student, course management, add course, system user management, add user, modify password and other functions.
Add student:
Teacher management:
You can query data, add, modify and delete teacher information according to the teacher's name
Class management
Add class information:
Course management and addition
Change Password:
Student login system:
Main function design: student login, course selection management, score view, view personal files, modify passwords and other functions
Teacher login system:
Teacher login, course selection management, add course selection students, score management, add scores, view student information, view class information, view personal files, modify passwords and other functions
