Java 实战图书管理系统的实现流程

一、项目简述

功能包括(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 + JavaScript + JQuery + Ajax + layui+ maven等等。
