一、项目简介

如今生活节奏也是不断加快，越来越多的喜欢看书的人选择通过网上在线租赁图书方式租赁图书，为了更好的方便消费者和图书馆管理人员，结合目前流行的在线经营理念，让每一本图书能够让更多的读者阅读。该系统前端使用JQuery框架对DOM操作，后端代码使用Java语言编写的，高效快速。数据库管理系统使用开源软件MYSQL，节约成本。该网站页面简洁，能够让浏览网站的用户快速查询到自己想要获得的信息，并做出相应的处理。

二、系统设计

2.1软件功能模块设计

系统整体功能如下：

2.2系统E-R图

1.管理员实体图：

2.会员实体图：

3.订单项实体图

4.友情链接实体图

5.评论实体图

6.首页轮播图实体图

三、系统项目部分截图

3.1图书馆书库管理系统操作主界面

由于该项目只是用来测试，用户登录首页展示的图片等数据有的是从图书本地拿到的，有的则是从数据库中获取的。其中head.jsp和bootom.jsp是进行的公共样式抽取的部分，简化了页面的设计，便于后期的维护。左侧是的菜单栏是通过js制作的，根据登录的角色不同，会显示不同的操作界面。
用户登录首页之后会显示如下的一个操作窗口。如下图：

3.2添加与登录功能实现

该图书馆书库管理系统会员用户是需要先注册的，注册成功以后才能进行登录。管理员的创建是需要管理员进行新建用户的，所有这点上两种不同用户的添加方式是不同的。以会员用户注册为例，如下图：
