Java爬虫获取省市区镇村5级行政区划

        公司有个项目需要五级行政区划，没有现成的数据，写了一段代码，从gj统计j获取的数据。记录一下。

1.引入maven解析html

<!-- jsoup -->
<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.11.3</version>
</dependency>

2.Java代码实现

@GetMapping("/hh")
    public void hh(){
        Division d=new Division();
        final String url = "https://www.stats.gov.cn/sj/tjbz/tjyqhdmhcxhfdm/2023/";
        String provinceurl = "https://www.stats.gov.cn/sj/tjbz/tjyqhdmhcxhfdm/2023/index.html"; // 需要爬取的目标网站地址
        try {
            Document document = Jsoup.connect(provinceurl).get(); // 获取该网页的文档对象
            String title = document.title(); // 获取页面标题
            //省
            Elements provincetable=document.body().select("tr.provincetr").select("a[href]");
            for (Element province : provincetable) {
                String provinceHref = province.attr("href"); // 获取链接地址
                String provinceText = province.text(); // 获取链接文字
                d.setProvincialCode(provinceHref.replace(".html",""));
                d.setProvincialName(provinceText);
                String cityurl=url+provinceHref;
                //System.out.println("cityurl = " + cityurl);
                Document citytabledocument = Jsoup.connect(cityurl).get();
                //市
                Elements citytable=citytabledocument.body().select("table.citytable").select("a[href]");
                //System.out.println("citytable = " + citytable);
                for(int i=0;i<citytable.size()/2;i++){
                    d.setMunicipalCode(citytable.get(i).text());
                    i=i+1;
                    d.setMunicipalName(citytable.get(i).text());
                    String cityHref = citytable.get(i).attr("href"); // 获取链接地址
                    String countyurl=url+cityHref;
                    System.out.println("countyurl = " + countyurl);
                    Document countytableocument = Jsoup.connect(countyurl).get();
                    //区
                    Elements countytable=countytableocument.body().select("table.countytable").select("a[href]");
                    for(int j=0;j<countytable.size()/2;j++){
                        d.setDistrictCode(countytable.get(j).text());
                        j=j+1;
                        d.setDistrictName(countytable.get(j).text());
                        String countyHref = countytable.get(j).attr("href"); // 获取链接地址
                        String townturl = url + provinceHref.replace(".html", "") + "/" + countyHref;
                        Document townttableocument = Jsoup.connect(townturl).get();
                        //镇
                        Elements towntable = townttableocument.body().select("table.towntable").select("a[href]");
                        for(int k=0;k<towntable.size()/2;k++){
                            d.setStreetTownCode(towntable.get(k).text());
                            k=k+1;
                            d.setStreetTownName(towntable.get(k).text());

                            String towntHref = towntable.get(k).attr("href"); // 获取链接地址
                            String villageurl = townturl.substring(0, townturl.length() - 11) + towntHref;
                            System.out.println("villageurl = " + villageurl);
                            Document villagetabledocument = Jsoup.connect(villageurl).get();
                            //村
                            Elements villagetable = villagetabledocument.body().select("table.villagetable").select("tr.villagetr");
                            for (Element village : villagetable) {
                                String villageText = village.text(); // 获取链接文字
                                String[] vi = villageText.split(" ");
                                System.out.println("统计用区划代码: " + vi[0]);
                                System.out.println("城乡分类代码: " + vi[1]);
                                System.out.println("名称: " + vi[2]);
                                d.setCommunityVillageCode(vi[0]);
                                d.setUrbanRural( vi[1]);
                                d.setCommunityVillageName(vi[2]);
                                System.out.println("d.toString() = " + d.toString());
                                System.out.println("vi = " + vi);
                                divisionService.insertDivision1(d);
                            }
                            //我想让他跑慢点，你可以自己调
                            try {
                                Thread.sleep(2000);
                            } catch (InterruptedException e) {
                                throw new RuntimeException(e);
                            }

                        }

                    }
                }
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

3.用到的实体类

其他的代码不贴了，就是数据入库。
