一、项目概述
1.项目内容
本项目利用IDEA，Visual Studio Code 开发工具，借助Mysql,Navicat for MySQL 工具，实现了一个基于springboot+vue的垃圾分类管理系统。系统为两种类型的用户提供服务，用户和管理员。
2.实现功能
（1）登陆功能
通过和数据库建立联系后，数据库内的用户和管理员可在登录页面输入账号和密码登陆网页。
（2）数据的增、查、改、删功能
① 垃圾的增、查、改、删
② 管理员的增、查、改、删
③ 用户的增、查、改、删
（3）通过饼状图，柱状图可显示用户的性别比例，入库垃圾的数量信息，用户总数，管理员总数，入库垃圾数量，查询次数等。
二、具体实现
1.前端登陆界面
垃圾分类信息管理系统登录
2.增删改查实现
（1）管理员信息增删改查：
/**

}3.解决跨域问题
public class WebMvcConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowCredentials(true) /*访问是否需要验证*/
.allowedOriginPatterns("*")
.allowedMethods("*");
}
}三、功能演示
1.跟随前端网址访问网页
2.登陆主页
3.查看垃圾信息
4.用户管理页面
5.管理员管理页面
