行政区划获取

一、导入jar包
二、代码展示

背景：
公司的行政区划代码有问题，有的没有街道信息，有的关联信息有误，然后找到了国家的网站国家统计局-行政区划，这个里面是包含了所有的行政信息，但是全是html页面，这个就没法自动获取了，只能去爬取这个数据了，java语音有三方类库Jsoup，他是一个仿浏览器的三方库，可以通过他来获取页面信息。

一、导入jar包

下面是笔者用到的全部jar包

	<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.9</version></dependency><dependency><groupId>com.google.guava</groupId><artifactId>guava</artifactId><version>30.1.1-jre</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-json</artifactId><version>5.4.0</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.44</version></dependency><dependency><groupId>org.jsoup</groupId><artifactId>jsoup</artifactId><version>1.14.3</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.5</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>2.5.4</version></dependency>

这里说下，maven配置要从阿里云下载jar，若是从中央仓库将会非常的慢。
阿里云私服：http://maven.aliyun.com/nexus/content/repositories/central/

二、代码展示

这里是代码的展示，笔者是网上搜的代码改造的，不然网站有反爬，大概爬取2000条左右就会中断，笔者加了延时这样就避开了反爬（可能还有别的规避措施）。这里爬取的是4级行政区划：省、市、区县、街道
