采用JAVA设计一个小型图书管理程序（只要增删查改）

Posted 2023-03-23

采用JAVA设计一个小型图书管理程序，具有信息添加、查询、修改和删除功能。图书信息包括: 图书编号，书名，作者名，分类号，出版单位，出版时间，价格。
用eclipse编写然后连接到数据库，能正常运行出现图形用户界面实现增删查改四个功能就行了，谢谢了，可以发到我邮箱[e-mail]。

参考技术A 使用java语言设计一款小型图书管理系统，能够通过主界面根据关键字查询图书信息，能够添加图书信息和删除过去图书信息

参考技术B 私信我 我或许可以完成哦 参考技术C 可以做，要的话，私信追问

私了

ElasticSearch 7.3采用restful风格 基本的增删查改语句

1 、新建图书索引

首先建立图书索引 book

语法：put /index

PUT /book

结果

2、新增图书 :新增文档

语法：PUT /index/type/id

PUT /book/_doc/1

"name": "Bootstrap开发",
"description": "Bootstrap是由Twitter推出的一个前台页面开发css框架，是一个非常流行的开发框架，此框架集成了多种页面效果。此开发框架包含了大量的CSS、JS程序代码，可以帮助开发者（尤其是不擅长css页面开发的程序人员）轻松的实现一个css，不受浏览器限制的精美界面css效果。",
"studymodel": "201002",
"price":38.6,
"timestamp":"2019-08-25 19:11:35",
"pic":"group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
"tags": [ "bootstrap", "dev"]

PUT /book/_doc/2

"name": "java编程思想",
"description": "java语言是世界第一编程语言，在软件开发领域使用人数最多。",
"studymodel": "201001",
"price":68.6,
"timestamp":"2019-08-25 19:11:35",
"pic":"group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
"tags": [ "java", "dev"]

PUT /book/_doc/3

"name": "spring开发基础",
"description": "spring 在java领域非常流行，java程序员都在用。",
"studymodel": "201001",
"price":88.6,
"timestamp":"2019-08-24 19:11:35",
"pic":"group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
"tags": [ "spring", "java"]

结果

3、查询图书：检索文档

语法：GET /index/type/id

查看图书:

GET /book/_doc/1

就可看到json形式的文档。方便程序解析。

为方便查看索引中的数据，kibana可以如下操作

Kibana-discover- Create index pattern- Index pattern填book

下一步，再点击discover就可看到数据。点击json还可以看到原始数据

4、修改图书：替换操作

PUT /book/_doc/1

    "name": "Bootstrap开发教程1",
    "description": "Bootstrap是由Twitter推出的一个前台页面开发css框架，是一个非常流行的开发框架，此框架集成了多种页面效果。此开发框架包含了大量的CSS、JS程序代码，可以帮助开发者（尤其是不擅长css页面开发的程序人员）轻松的实现一个css，不受浏览器限制的精美界面css效果。",
    "studymodel": "201002",
    "price":38.6,
    "timestamp":"2019-08-25 19:11:35",
    "pic":"group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
    "tags": [ "bootstrap", "开发"]

替换操作是整体覆盖，要带上所有信息。

5、 修改图书：更新文档

语法：POST /index/type /id/_update

或者POST /index/_update/id

POST /book/_update/1/ 

  "doc": 
   "name": " Bootstrap开发教程高级"
  

返回：

6、删除图书：删除文档

语法：

DELETE /book/_doc/1

返回：
