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。
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
