ABSTRACT

With the efficient development of information technology and the increasingly sound Internet technology, people are paying more and more attention to e-commerce. The fresh food trading applet is a typical representative of e-commerce. The market has changed from the previous roadside goods market to the network, where transactions are conducted according to the trading system. The fresh food trading applet brings farmers a time-saving, labor-saving and cost-effective goods trading platform. It enables farmers to flexibly use the advantages of information technology to solve fresh food, which is more and more smooth, convenient and convenient, and can satisfy users to quickly enjoy the life brought by online shopping. In order to achieve the reasonable utilization of fresh food more conveniently in the future, scientific research on the development of the current trading situation, design a scheme to complete a small program of fresh food trading according to the requirements and feasibility study。

This system is mainly a platform with convenient, strong scalability and good customer interaction. The system provides powerful database management, accurate and efficient data analysis, and fast and flexible data statistics services. The front-end WeChat applet technology is adopted to design a simple interface, high usability and good interpersonal interaction experience; New technologies such as SpringbBoot Mybatis on the back end are adopted to build a management system that is easy to manage, easy to use, high safety factor, coordination ability, scalability, high efficiency, dynamic and interactive to browse the database; Complete visualized, scientific and simple fresh food trading applet。

Keywords: fresh food transaction; WeChat applet; SpringBoot; Mysql

生鲜商城，对国家经济的发展和鹏飞以及对人类社会的文明带来了巨大影响。生鲜行业已成为许多国家的支柱产业，随着人们生活水平以及生鲜性能的不断提高，人们对生鲜的消费和需求也越来越旺盛，世界生鲜行业也保持庞大的市场需求和市场规模。近年来，中国生鲜市场发展迅猛，以接近 37%的速度增长，巨大的市场容量和可观的经济效益，引起各生鲜厂家纷纷加大投资，生鲜市场烽烟四起，生鲜销售策略和模式频出，竞争已是空前的激烈，在此形势下，一种介于生产厂家和用户之间的桥梁，生鲜销售公司正在不断的产生和发展壮大。

通过网络进行生鲜销售，是这个时代发展的必然结果，是随着网络的普及和电子商务概念的兴盛而兴起的。这种全新出现的新型生鲜销售形式，与传统通过生鲜店面进行销售的方式相比优势显著： 1，降低了生鲜销售成本；2，改变生鲜传统的了解和购买方式，使用网络平台了解生鲜信息并购买，使得商业活动没有空间和时间的限制；3，生鲜信息的传递更有效率和直观，新车信息上传后，人们可以立即了解咨询，交易可以马上进行，从而大大提高了生鲜交易的效率。正是由于这些巨大的优势，生鲜销售平台才能得以迅速地开拓市场。生鲜销售平台的主要是借助平台作为交易平台，将生鲜的各项指标，优势劣势，精美图片以发布到网络中，人们能够借助网络登录生鲜销售平台来查看各种生鲜的信息并提交订单订购或者预定生鲜，实现在线交易。开发之前需要做好详细的系统架构，这种系统架构内容包括了市场需求分析，平台前端设计，后台设计，技术可行性分析，框架组合分析等。

1.2 课题目的及意义

生鲜销售信息管理，是企业管理生鲜销售的一个不可缺少的平台。在以往，传统的信息管理方式主要以人为主体，人们投入大量时间和精力去操作，存在着管理上的局限性、主观性和片面性，人为的管理手段已经无法适应互联网时代的发展，这种方法无疑是在浪费大量的人力和财力，而在信息高速发达的时代，主要是以计算机为处理手段。本系统将取代传统的手动操作管理，实现人和计算机的完美结合，充分发挥人和机器的特长，能对生鲜销售信息的数据进行收集、记录、统计和导出的系统。灵活和可配置地为管理人员提供直观可视化、科学化和简约化管理。本系统的开发能一定程度上提高企业工作效率，能够比较全面、准确地掌握企业生鲜销售的信息并进行统计、查询和管理。建立现代化生鲜销售信息管理体制，统一化、规范化和流程化企业各部门之间的业务流程，实现各部门协调合作、无纸办公。
