1、项目介绍及开发技术
1.1 项目介绍
现代经济快节奏发展以及不断完善升级的信息化技术，让传统数据信息的管理升级为软件存储，归纳，集中处理数据信息的管理方式。本城市垃圾分类管理系统就是在这样的大环境下诞生，其可以帮助管理者在短时间内处理完毕庞大的数据信息，使用这种软件工具可以帮助管理人员提高事务处理效率，达到事半功倍的效果。此城市垃圾分类管理系统利用当下成熟完善的SSM框架，使用跨平台的可开发大型商业网站的Java语言，以及最受欢迎的RDBMS应用软件之一的Mysql数据库进行程序开发。实现了用户在线选择试题并完成答题，在线查看考核分数。管理员管理字典管理、论坛管理、公告管理、垃圾管理、垃圾收藏管理、垃圾留言管理、留言板管理、用户管理、政策管理、管理员管理等功能。城市垃圾分类管理系统的开发根据操作人员需要设计的界面简洁美观，在功能模块布局上跟同类型网站保持一致，程序在实现基本要求功能时，也为数据信息面临的安全问题提供了一些实用的解决方案。可以说该程序在帮助管理者高效率地处理工作事务的同时，也实现了数据信息的整体化，规范化与自动化。
1.2 开发技术
Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。
2、系统功能模块设计
用户：注册登录、首页、论坛、公告、垃圾、留言板、政策、个人中心（个人信息、垃圾收藏）
管理员：登录、首页、个人中心（修改密码、个人信息）、管理员管理、基础数据管理（帖子类型管理、公告类型管理、所属分类管理、政策类型管理、）、论坛管理、公告管理、垃圾管理、留言板管理、用户管理、政策管理、轮播图信息。
3、功能截图
垃圾列表：查看垃圾、新增垃圾、修改垃圾、删除垃圾等。
公告信息管理： 新增公告，修改公告，删除公告操作。下图就是公告信息管理页面。
公告类型管理： 可以添加新的公告信息类型，也能对已有的公告类型信息执行编辑更新，失效的公告类型信息也能让管理员快速删除。
4、数据库表结构设计
