4 |
5 | ### 基本信息：
6 |
7 | - **开发环境**：windows10+jdk1.8+Tomcat8+IDEA+MySQL+MVC开发模式
8 |
9 | - 注意：IDE为 `jetbrains IntelliJ IDEA` ，不知道导入Eclipse会出现什么问题。
10 |
11 | - **注意事项**: 调试之前请创建名为library的数据库，相关sql脚本为项目根目录下`library.sql`；并且需要导入相关jar包(相关jar包已经放在该目录下---lib.zip)
12 | 并且在resource中需要配置druid.properties的相关数据库配置文件
13 |
14 | - **存在问题**：管理员登录之后进入主页面不会直接显示图书信息，需要点击查询按钮后才能显示图书信息；
15 |
16 | - 当进行修改或者添加书籍后，也需要重新点击查询按钮之后才能显示图书信息；部分图书信息的描述图片以及相关内容不能显示。
17 |
18 | #### 项目细节描述：
19 |
20 | 1. **登录**：
21 | 其中的验证码可以点击刷新并且不区分大小写
22 |
23 | 2. **主页**：
24 | 1. 可以通过部分(名字)书名、作者或者类别来进行查询
25 | 2. 可以通过点击全选来选中该页面所有书籍
26 | 3. 当通过书名、作者或者类别来查询时在点击下方的下页，输入框中会回显输入记录
27 |
28 | 3. **增加**：
29 | 增加的书籍会有命名的显示规则，需正确输入命名规则才能进行添加书籍
30 |
31 | 4. **修改**：
32 | 点击修改后进入进入修改页面中输入框也会回显出主页面的书籍的信息，但是部分书籍信息不能显示完全
33 |
34 | 5. **删除**：
35 | 可以通过点击全选框在点击删除选中进行多个删除；也可进行单个删除

内容简介 《呐喊》这部短篇集诞生于五四运动及新文化运动的大背景之下，收录了鲁迅从1918年至1922年所创作的14篇短篇小说，其中包括《狂人日记》、《孔乙己》、《药》、《明天》、《一件小事》、《头发的故事》、《风波》、《故乡》、《阿Q正传》、《端午节》、《白光》、《兔和猫》、《鸭的喜剧》以及《社戏》。其中《狂人日记》、《阿Q正传》、《孔乙己》、《故乡》等更是成为传世名篇，艺术价值极高。小说生动真实地描绘了从辛亥革命到“五四”时期的社会生活，揭示了种种深层次的社会矛盾，对中国麻木、愚昧的国民性进行批判，表现出对民族生存浓重的忧患意识和对社会变革的强烈渴望，呈现了鲁迅先生爱国主义思想的发展、探求救国救民道路的精神历程。
作者简介 鲁迅（1881～1936），原名樟寿，字豫才，后改名周树人，浙江绍兴人。我国现代伟大的无产阶级文学家，思想家，革命家，世界十大文豪之一，是中国现代文学的一面旗帜。他的著作主要以小说、杂文、散文为主，代表作有：小说集《呐喊》《彷徨》《故事新编》，散文集《朝花夕拾》，散文诗集《野草》，杂文集《热风》《华盖集》《华盖集续编》《南腔北调集》《三闲集》《二心集》《而已集》《坟》等。鲁迅以笔代戈、奋笔疾书、战斗一生，被誉为“中国现代文学之父”。

内容简介 《本草纲目》对16世纪以前的中医药学的进行了系统的总结，被誉为“东方药物巨典”，对人类近代科学以及医学方面影响较大，是我国医药宝库中的一份珍贵遗产。
《（插图本）本草纲目》对这部中医药巨典进系了完整严谨的点校整理，并请北京中医药大学博导王致谱亲自审订，另加两千余幅图片辅助理解。本书是众多版本中切于实用的文本。
作者简介 [明]李时珍（1518—1593），字东璧，晚年自号濒湖山人，湖北蕲春县蕲州镇东长街之瓦屑坝（今博士街）人。明代著名医药学家，著述有《奇经八脉考》、《濒湖脉学》、《本草纲目》等多种。
李伯钦： 1963年生于北京，1985年毕业于北京大学中文系。在中华书局从事编辑工作八年，负责《国务院古籍整理出版情况简报》编辑与出版。1997年创建智品图书（北京）有限公司，任董事长兼总编辑。先后策划的文化项目有《唐宋八大家全集》、《康熙字典（现代版）》、《说文解字（现代版）》、《中国历代碑刻书法全集》、《百衲本二十四史（标点本）》、“家藏四库”百部系列、《中国通史》《东方圣典》等；其中有多种图书荣获国家和省级出版奖项。
前言/序言 神农尝百草，这个只存在于神话传说中的故事，已经流传了几千年。本草保佑了华夏民族的繁衍和健康，至唐代，出现了世界上第一部由国家编定和颁布的药典——《唐本草》。唐以后，盛朝必修“本草”，明朝时，李时珍集大量古代本草书籍之大成，编写出一部中医学、药物学的专著——《本草纲目》。书中记载药物一千八百多种,方剂一万多个,全面总结了16世纪以前的中国医药学，是中国医药学的全典和中华医药的百科全书，被誉为“东方医药巨典”。
《本草纲目》中的一些资料,直接影响了达尔文生物进化论的形成。达尔文在奠定进化论、论证人工选择原理的过程中，参阅了《本草纲目》，并称它为“中国古代百科全书”。如达尔文在《变异》中谈到鸡的变种、金鱼家化史等，均吸取和引用了《本草纲目》的内容。李约瑟博士在评价《本草纲目》时写道：“毫无疑问，明代最伟大的科学成就，是李时珍那部在本草书中登峰造极的著作《本草纲目》。”“中国博物学家中‘无冕之王’李时珍写的《本草纲目》，至今这部伟大著作仍然是研究中国文化史的化学史和其他各门科学史的一个取之不尽的知识源泉。”
