Written at the very beginning: This course design was written by me line by line in the summer vacation of 2021. Now I share it with you for free. If it is helpful to you, please give me a like, thank you.
If you have any questions, you can leave a comment, and I will get back to you when I see it, but I can only answer questions related to my code. For other configuration questions, please search more.

Let me explain some codes:
1. The design of this course is not particularly high-end. The various components of Java swing used in the human-computer interaction interface, the backend is Java and SQL server. I have given the SQL file in the compressed package. After you download it, run it directly on the SQL server It's ok, but I don't know if MySQL or Navicat can run. I suggest you search it. I think it should be easy to solve. If you want to use MySQL.
2. Download the compressed package, open the compressed package, there will be three things inside.
These three things are:
Project file of Eclipse;
SQL code to create database;
course design report.
Note: The content in the course design report may be inconsistent with the actual code, because I have improved some functions in the later stage. You need to read this for yourself. I only remember some: only courses can be selected in the report, but the code is realized
. Cancellation;
the function of viewing the class schedule used to pop up a photo of the class schedule directly, but now it prints out the class schedule on the page.
That's all I can remember.
3. Open Project
The following only introduces the normal steps, and there will be no errors by default. If you encounter problems during the operation, it is recommended to search for solutions on the Internet.
File——Open Projects from File System
Click Directory to select the Project file lin
After opening it looks like this:
I only have one package, zzdx, which contains all the codes of the project. In fact, this kind of code writing habit is very bad. It will be very cumbersome and unprofessional to put all the codes in one package. When I was a sophomore, I actually I don't know anything about MVC frameworks, so I wrote them all in one package.
Note: only lf.java can run, the others are called.
Forgive me for the strange name, most of which are Chinese initials, for example: the second ckcj.java, this file is the interface for viewing results.
Right-click lf.java——Run As——Java Application
The running interface will come out. As follows: My interface is relatively simple, if you have time, you can search how to make the interface more beautiful.
Oh, by the way, all the picture files are in the bag. If you want to change them, you can just change them in the bag.
In addition, if the text needs to be modified, it may need to be found in the code of the corresponding interface. For example, the Zhengzhou University educational affairs system in the first interface needs to be modified in lf.java.
This kind of Chinese characters is quite conspicuous in the code, so it should be easy to change. The difficult part for everyone is to find the Java file corresponding to the corresponding interface.
Let me just explain the pages or functions represented by each code: (not in the order in which they are arranged in Eclipse)
Director is equivalent to administrator
| identity | code name | meaning |
|---|---|---|
| ALL | lf.java | welcome page |
| ALL | welcome.java | choose identity |
| ALL | dl.java、test.java | Enter the account password to log in, test.java is used to generate the verification code |
| ALL | zzdx.java、zzdx1.java、zzdx2.java | Account password verification (students, teachers, directors) |
| ALL | success.java、success1.java、success2.java、qq.java | The homepage (students, teachers, directors) after successful login, qq.java is used to generate the core part of the homepage - the function selection box |
| ALL | error.java | The account password is wrong |
| student | ckkb.java | view class schedule |
| student | ckcj.java | view grades |
| student | cktz.java | View notifications |
| student | jsdh.java、more.java | Query the teacher's phone number, jsdh.java is to check the phone number of the teacher in charge, if you want other teachers' phone numbers, you can check in more.java |
| student | xk.java | course selection |
| student | tuike.java | quit class |
| student | xgmm.java | change Password |
| teacher | ckkc.java | View taught courses |
| teacher | fbtz.java | post notice |
| teacher | sccj.java | Upload Student Grades |
| director | ckjl.java | View the record of teacher uploaded grades |
| director | gznx.java | Update the teacher's working years (this function is useless, it is recommended to delete) |
| director | kskc.java | open courses |
| director | zhgl.java、xs.java、js.java、sc.java、cj.java | Account management (addition and deletion of teacher and student accounts) |
4. Run the SQL file
In the SQL server
file - open - file
You can also try it in MySQL or Navicat
Find zzdx.sql, open
Click Execute to create the database
All such codes in the code need to be replaced with your own user name and password. If you change zzdx.
this may take a while
First select Class.forName with the mouse
Click: Search——Text——Project
In this way, Eclipse can help you find all the places where Class.forName appears in the lin Project, and then modify them one by one. Just change one, and then copy and paste it directly. It is recommended to try to see if you can successfully connect to the database before modifying all of them.
5. Course design report
Let me emphasize again that there are differences between the content in the report and the functions implemented by the code, but there is not much difference. You can refer to it.
6. General interface
| page description | picture |
|---|---|
| welcome page |  |
| identity choice |  |
| Enter account password |  |
| Login failed |  |
| Student Home |  |
| View Courses (The name was changed to View Courses because I found it troublesome to arrange students’ classes into a schedule, so it is simply listed here. The previous name was View Schedule because the function was implemented as a pop-up photo of the schedule. I don’t need to edit it manually, so you can delete the picture of the class schedule in the Project, because it is useless, and you can see that if the name of the course is too long, it cannot be displayed in full. I use the JLabel component. You can use it if you have time. Replace with JTextField component, you can display all names) |  |
| Check the result (null means the teacher has not uploaded the result, and the default is to pass the test) |  |
| Check the notification (each notification will carry the teacher's name, only the notification sent by the class teacher will be received by the students, it seems so, I kind of forgot) |  |
| Inquiry phone number (the phone number of the teacher in charge will be printed first, if you need other teachers, you can click more) |  |
| More (you can search by entering the name, if you have this teacher, you will print it out, and if you don’t, you will be prompted) |  |
| Course selection (fuzzy search is available, click on the course name to select a course, the system will automatically compare whether there is a conflict between the course and the existing course, the course cannot be removed from the current list immediately after selecting a course or withdrawing from the course, you need to exit and re-enter to see the selected course The course is no longer on the list, but you won’t make mistakes if you click it a few times, you can rest assured) |  |
| Withdrawal (Click on the course number to withdraw from the course) |  |
| change Password |  |
| teacher home page |  |
| View courses taught (just listed like students) |  |
| Post a notification (only your own students will receive this notification) |  |
| Upload grades (enter the grades and click the submit button, the same as course selection, if you can’t submit a student’s grades, the student will be removed from the list, so you can upload grades multiple times, the last time is the final score, but the uploaded records will be detailed Records, the director can inquire, we uploaded 88 points to Zhuang Zhou here, we will see if the director can check the modification record later) |  |
| Director Home |  |
| Check the records (see if there is any record that we gave Zhuang Zhou 88 points. In fact, there is still a problem. If there are too many modified records here, all of them cannot be displayed. The record.txt file needs to be cleaned regularly, and the course selection is also required. , if there are too many courses to choose from, they cannot all be displayed. If you have time, you can search for what components to replace to realize the drop-down bar, and then put these record information or course information into the drop-down bar component, so that you can install it all content up) |  |
| open courses |  |
| Account management (including the creation and deletion of teacher and student accounts, I am too lazy to take screenshots) |  |
7. Well, that's it. If it helps you, I hope you can give me a thumbs up.
