基于jsoup獲取全國省市區區域編碼

本文獲取全國省市區區域編碼路徑：http://www.mca.gov.cn//article/sj/xzqh/2020/202006/202008310601.shtml

前言

省市區區域編碼

一、jsoup是什么？

jsoup是決議HTML得

二、使用步驟

1.引入庫

  <!--決議HTML-->
        <dependency>
            <groupId>org.jsoup</groupId>
            <artifactId>jsoup</artifactId>
            <version>1.11.2</version>
        </dependency>

2.ChinaRegionsInfo.JAVA 物體類

public class ChinaRegionsInfo {

    /**
     * 行政區域編碼
     */
    private String code;

    /**
     * 行政區域名稱
     */
    private String name;

    /**
     * 行政區域型別，1:省份，2：城市，3：區或者縣城
     */
    private Integer type;

    /**
     * 上一級行政區域編碼
     */
    private String parentCode;

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getType() {
        return type;
    }

    public void setType(Integer type) {
        this.type = type;
    }

    public String getParentCode() {
        return parentCode;
    }

    public void setParentCode(String parentCode) {
        this.parentCode = parentCode;
    }

    @Override
    public String toString() {
        return "ChinaRegionsInfo{" +
                "code='" + code + '\'' +
                ", name='" + name + '\'' +
                ", type=" + type +
                ", parentCode='" + parentCode + '\'' +
                '}';
    }
}

3.爬取省市區區域代碼實體

  //需要抓取的網頁地址
    private static final String URL = "http://www.mca.gov.cn//article/sj/xzqh/2020/202006/202008310601.shtml";

    public static void main(String[] args) throws IOException {
        List<ChinaRegionsInfo> regionsInfoList = new ArrayList<>();
        //抓取網頁資訊
        Document document = Jsoup.connect(URL).get();
        //獲取真實的資料體
        Element element = document.getElementsByTag("tbody").get(0);
        String provinceCode = "";//省級編碼
        String cityCode = "";//市級編碼
        if (Objects.nonNull(element)) {
            Elements trs = element.getElementsByTag("tr");
            for (int i = 3; i < trs.size(); i++) {
                Elements tds = trs.get(i).getElementsByTag("td");
                if (tds.size() < 3) {
                    continue;
                }
                Element td1 = tds.get(1);//行政區域編碼
                Element td2 = tds.get(2);//行政區域名稱
                if (StringUtils.isNotEmpty(td1.text())) {
                    if (td1.classNames().contains("xl7030796")) {
                        if (td2.toString().contains("span")) {
                            //市級
                            ChinaRegionsInfo chinaRegions = new ChinaRegionsInfo();
                            chinaRegions.setCode(td1.text());
                            chinaRegions.setName(td2.text());
                            chinaRegions.setType(2);
                            chinaRegions.setParentCode(provinceCode);
                            regionsInfoList.add(chinaRegions);
                            cityCode = td1.text();
                        } else {
                            //省級
                            ChinaRegionsInfo chinaRegions = new ChinaRegionsInfo();
                            chinaRegions.setCode(td1.text());
                            chinaRegions.setName(td2.text());
                            chinaRegions.setType(1);
                            chinaRegions.setParentCode("");
                            regionsInfoList.add(chinaRegions);
                            provinceCode = td1.text();
                        }

                    } else {
                        //區或者縣級
                        ChinaRegionsInfo chinaRegions = new ChinaRegionsInfo();
                        chinaRegions.setCode(td1.text());
                        chinaRegions.setName(td2.text());
                        chinaRegions.setType(3);
                        chinaRegions.setParentCode(StringUtils.isNotEmpty(cityCode) ? cityCode : provinceCode);
                        regionsInfoList.add(chinaRegions);
                    }
                }
            }
        }
        //列印結果
        System.out.println(JSONArray.toJSONString(regionsInfoList));
    }

總結

本文只是一個簡單得獲取省市區區域編碼得案例！非原創！原創是誰俺也忘了！俺很久看見了一個博文！通過那個博文開啟了俺jsoup得啟蒙！感謝！
