Today, many colleges and universities still use the traditional handwritten form to apply for courses. However, with the advancement of the times, this traditional method is no longer convenient and is full of limitations due to factors such as time and location. If students can report for repairs directly on their mobile phones, it will make the entire repair reporting process more efficient and faster, so it is very necessary to develop a mobile repair reporting system.
This system uses WeChat developer tools as the program front-end development tool, uses Java language to write program back-end code, IDEA or eclipse as the back-end development tool, and uses MySQL as the database. Because mini programs can be opened directly on WeChat and are convenient and efficient, they are very suitable for this system. Therefore, this system is based on WeChat mini programs. In order to complete the system, through the processes of system conception, system analysis and design, and database design, and summarizing the system development process, the function of students and maintenance personnel reporting for repairs and receiving orders through the WeChat applet was finally realized.

Abstract
Nowadays, many colleges and universities are still using traditional hand-written forms to report for repairs. However, with the progress of the times, this traditional method is not convenient enough, and is full of limitations due to factors such as time and place. If the students can repair directly on the mobile phone, it will make the entire repair process more efficient and rapid, so it is necessary to develop a mobile repair system.
This system uses WeChat developer tools as the program front-end development tool, Java language to write the program back-end code, MyEclipse as the back-end development tool, and MySQL as the database. Because the applet can be opened directly on WeChat, with convenient and efficient features, it is very suitable for this system, so this system is based on the WeChat Applet. In order to complete the system, through the process of system conception, system analysis and design, database design, and summarize the system development process, the function of students and maintenance personnel through the WeChat Applet to repair and order is finally achieved.
