基于javaweb+jsp的垃圾分类查询管理系统

本文主要是介绍基于javaweb+jsp的垃圾分类查询管理系统，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

基于javaweb+jsp的垃圾分类查询管理系统

JavaWeb JavaBean JSP MVC MySQL Tomcat JavaScript Layui Ajax

基础JSP+Servlet或JSP+SSM(Spring、SpringMVC、MyBatis)框架或JSP+SSM+Maven(pom.xml)框架或SpringBoot…均可

开发工具：idea或eclipse或myeclipse

部分代码实现JSP
