使用SSM实现农产品溯源系统保证食品安全

Posted 2022-01-13 编程指南针

项目编号：BS-XX-012

运行环境：

开发工具：IDEA / ECLIPSE，同时提供有MAVEN版本和非MAVEN版本，根据需要选择

数据库：mysql5.7

TOMCAT:8.5.31

使用技术：

后台开发：SSM框架

前台开发:Jquery+Css+Layui框架

本系统主要定位于农产品的信息溯源工作，可以根据农产品的相关信息生成二维码，然后将二维码贴到我们的农产品包装上，购买产品的顾客可以通过手机扫描二维码获得产品的相关信息，从而实现产品的溯源。在系统的前端页面，也提供了供用户查询农产品信息的入口搜索。本系统基于SSM框架技术实现，数据库采用mysql，开发工具为IDEA。农产品溯源管理平台后台管理主要分为两个角色进入系统进行管理：一个是管理员账户，一个是企业账户。管理员账户可以添加企业，管理用户。企业用户登陆系统可以添加产品，根据产品生成二维码，并可以进行产品的信息统计操作。

系统前端功能展示如下：

展示如下：

根据产品ID查询产品信息

后台部分功能展示如下：

管理员账户进入：http://localhost/ncpsy/admin/login    admin/admin

企业管理：

用户管理：

企业用户登陆：  user /user

http://localhost/ncpsy/login 

企业用户注册

农产品管理：

新增农产品：

二维码管理：

查看二维码：        

二维码中包含产品的详情信息，可以将生成的二维码打印粘贴至我们的农产品包装上，供客户扫描查看产品的溯源信息。

溯源管理：

溯源列表：数据表tb_syly 模拟相关数据即可

溯源图表：

设置企业信息：

本系统运行无误，功能完整，操作简单，适合做毕业设计使用。

核心代码实现：
