2. Project introduction
This project uses Springboot+Vue for front-end and back-end separation development, and completes a gas station refueling management system platform. The system completely simulates the business model of the real gas station management system, realizes online registration and login of front-end users, online recharge, and simulates refueling by selecting the refueling gun. The user's personal center can view and modify personal information, recharge online and view recharge records, refueling records, etc.
At the same time, the system also provides the function of platform administrator, which realizes personnel management, graphical report statistics of refueling performance and turnover, recharge management, announcement management, carousel map management, refueling muzzle management, refueling information record management, etc.
The topic selection of this system is relatively novel, and it can realize the full-process business management function module of gas station refueling. It is a rare high-quality system.
The following shows the function of the system
