Java实现获取行政区划的示例代码

作者：归去来 兮

这篇文章主要为大家详细介绍了如何利用Java语言实现获取行政区划的功能，文中的示例代码讲解详细，感兴趣的小伙伴可以跟随小编一起学习游戏

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
