Java 实战项目之学生信息管理系统的实现流程
作者：qq_1334611189
读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实战中才能获得能力的提升，本篇文章手把手带你用java+SSM+jsp+mysql+maven实现学生信息管理系统,大家可以在过程中查缺补漏，提升水平
一、项目简述
功能包括： 用户的登录注册，学生信息管理，教师信息管理，班级信 息管理，采用mvcx项目架构，覆盖增删改查，包括学生， 教币班级的信息导出上传导入等等功能。
二、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： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + maven等等。
