Java實現(xiàn)獲取行政區(qū)劃的示例代碼

更新時間：2023年03月13日 08:34:13 作者：歸去來兮

這篇文章主要為大家詳細(xì)介紹了如何利用Java語言實現(xiàn)獲取行政區(qū)劃的功能，文中的示例代碼講解詳細(xì)，感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)游戲

背景

公司的行政區(qū)劃代碼有問題，有的沒有街道信息，有的關(guān)聯(lián)信息有誤，然后找到了國家的網(wǎng)站國家統(tǒng)計局-行政區(qū)劃，這個里面是包含了所有的行政信息，但是全是html頁面，這個就沒法自動獲取了，只能去爬取這個數(shù)據(jù)了，java語音有三方類庫Jsoup，他是一個仿瀏覽器的三方庫，可以通過他來獲取頁面信息。

一、導(dǎo)入jar包

下面是筆者用到的全部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>

這里說下，maven配置要從阿里云下載jar，若是從中央倉庫將會非常的慢。

二、代碼展示

這里是代碼的展示，筆者是網(wǎng)上搜的代碼改造的，不然網(wǎng)站有反爬，大概爬取2000條左右就會中斷，筆者加了延時這樣就避開了反爬（可能還有別的規(guī)避措施）。這里爬取的是4級行政區(qū)劃：省、市、區(qū)縣、街道
