Java 实战图书管理系统的实现流程

一、项目简述

功能包括关于感动的名言(管理员和学生角色)： 管理员和学生登录，图书管理，图书添加删除修改，图书 借阅，图书归还，图书查看，学生管理，借还管理，读者 管理，密码管理，信息修改等等功能。

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 + javascri寄明信片pt + jquery + ajax + layui+ maven等等。
