基于javaweb+jsp的蛋糕商城系统(java+JDBC+Servlet+HTML+Ajax+mysql+Fileupload)

基于javaweb+jsp的蛋糕商城系统(java+JDBC+Servlet+HTML+Ajax+mysql+Fileupload)

一、项目运行

环境配置：
Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）

项目技术：
Jdbc+ Servlert + html+ css + Javascript + JQuery + Ajax + Fileupload等等

适用

课程设计，大作业，毕业设计，项目练习，学习演示等
