基于springboot的微信点餐小程序

随着互联网技术的发展与不断变革，市面上很多奶茶店的点餐方式已经不能满足日益增长的客流量，因此为了解决这一问题，研究设计了一个微信小程序点餐系统。论文首先介绍了微信小程序点餐系统的开发背景和现状，随后阐述了设计该系统的目标，进行了系统的需求分析和开发技术方案设计，较详细的论述了系统的详细设计和实现。

微信小程序点餐系统的开发是基于B/S结构来进行开发的，同时运用当下热门的Spring Boot技术，数据库采用MySQL来作为数据的存储和管理，很大的保障了数据的完整性，也为开发这个系统提供了安全性。

系统根据微信小程序点餐系统调研总结出所需要的开发的各种功能，能够很好的实现数据的增删查改，还对系统的前台小程序端和后台管理这两个模块进行了优化，以满足不同权限下不同用户的实际需求，系统分工明确，能够极大的提高点餐管理信息的效率，本系统界面简洁、易操作、功能较多、安全性高、实用性强，是一个具有良好功能扩展性以及简单维护性的信息管理系统。该系统功能齐全，界面布局比较吸引人，功能比较全，操作简单，符合当今社会的发展趋势。

ABSTRACT

With the development and continuous transformation of Internet technology, the  method of placing orders in many milk tea shops on the market has become unable to meet the increasing customer flow. Therefore, in order to solve this problem, a system of Yihetang of City College was designed. The paper firstly introduces the development background and current situation of Yihetang ordering system of the City College,  then elaborates the goal of designing the system, carries on the demand analysis of the system and develops the technical scheme design, and discusses the detailed design and realization of the system in detail.

The development of Yihetang ordering system of City College is based on B/S structure. At the same time, the popular spring boot technology is used, MySQL is used as data storage and management, which greatly guarantees the integrity of data and provides security for the development of this system.

According to the investigation of Yihetang ordering system of City College, the system summarizes all kinds of functions that need to be developed, which can well realize the addition, deletion, check and modification of data. It also optimizes the two modules of the system, the Wechat Mini Program and the background management, so that the system can meet the actual needs of different users under different permissions. The system layout is clear and easy to understand, which speeds up the management of order information. The system has been tested and studied many times, and the results are stable, easy to operate and fast. It is an information management system with many functions, strong security and practicability, various excellent function expansibility and simple maintenance. The system is fully functional, the interface layout is attractive, the function is more complete, the operation is simple, in line with the development trend of today's society

Keywords: Ordering system  B/S structure  Spring Boot  MySQL
