围绕中小学（注：无图书馆）图书管理需求（如采购入库、图书编码、借书还书、图书出库），设计合理的系统功能模块和数据库结构，构建一个较为实用的图书管理系统。
任务要求：按照软件工程理论，依次完成分析、设计、实现、测试各步骤，有较好的用户界面，考虑相关数据的安全和隐私性，所有数据通过用户界面输入输出。
该项目采用三层B/S架构，数据层，表示层，控制层。
NetBeans8.2（如果要直接使用提供的代码最好用该开发工具，该工具Servlet的方法是自动生成，与目前主流的IDE有所不同）
JDK1.8
数据库为Oracle 11g 简化版
表示层使用前端框架Pintuer。具体情况请参阅官网资料：www.pintuer.com
在该系统中使用的是1.0版本。下载后在web文件夹里面建立两个文件夹，css文件夹和js文件夹。将下载后的pintuer框架文件夹解压，将里面的js文件放到js文件夹，css文件放到css文件夹。
具体如下：
同时还需要如下架包：
jstl.jar
ojdbc6.jar
standard.jar
这些文件的下载请自行下载。这里不提供。
将这个三个架包放到WEB-INF的lib文件夹。lib文件夹请自己建立。具体如上图所示。
同时这些文件还要导入到库文件夹下面
具体如下图：
所需的tomcat服务器请自行到tomcat官网下载，请使用8.5以上版本，使用7.0版本会有中文乱码，本系统没有做这方面的处理。
项目结构如下：
数据层主要负责对数据库表的各种增删改查。采用DAO模式，将对数据库的操作封装在一个接口里，一个类来实现。
数据库表的设计如下：
三个表：图书表，用户表，用户借书表
create table Book /*图书表*/
(
Bno varchar2(15) primary key, /*书的编号*/
Bname varchar2(30), /*书名*/
Bauthor varchar2(24), /*书的作者*/
Bnum int check(Bnum>=0) /*书的数量*/
)
create table BookUser /*用户表*/
(
username varchar2(12) primary key, /*用户名*/
passwords varchar2(12) not null, /*密码*/
permission int not null /*权限*1：管理员 2：普通用户/
)
create table UB /*用户借书信息表*/
(
username varchar2(12), /*用户名*/
Bno varchar2(15), /*书的编号*/
Bname varchar2(30), /*书名*/
LendTime date, /*借书时间*/
primary key(username,Bno),
foreign key(username) references BookUser(username) on delete cascade,
foreign key(Bno) references Book(Bno) on delete cascade
)
数据层的java类如下图所示：
