jsoup爬虫实战

爬取地址http://wufazhuce.com/

这是一个很不错的网站，每天会更新一个鸡汤以及一幅配图，下面是爬取近7天的鸡汤以及配图的实战。

导包

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.10.2</version>
</dependency>

使用jsoup拿到网页

Document doc = Jsoup.connect("http://wufazhuce.com/").get();

分析源代码，在查看源代码中，我发现，所需要的内容集中在这一块

<div id="carousel-one" class="carousel slide">

                <div class="carousel-inner">
                                    <div class="item active">

                    </div>
                                </div>

所以，首先先拿到这一部分

Element body = doc.getElementById("carousel-one");

然后抽取出图片，文本以及时间，遍历放到集合中

Elements imgs = body.getElementsByClass("fp-one-imagen");
        Elements texts = body.getElementsByClass("fp-one-cita");
        Elements times1 = body.getElementsByClass("dom");
        Elements times2 = body.getElementsByClass("may");

        int i = 0;
        for (Element elem : imgs) {
            LinkedHashMap<String, String> map = new LinkedHashMap<>();

            map.put("img",imgs.get(i).attr("src"));
            map.put("text",texts.get(i).text());
            map.put("time",times1.get(i).text() +" "+ times2.get(i).text());
            arrayList.add(map);

            i++;
        }

完整接口示范

import com.example.api.util.Res;
import org.jsoup.Jsoup;

import org.springframework.stereotype.Controller;

    @ResponseBody

    public Res imgText() {

      try {

      } catch (IOException e) {

      }
        Element body = doc.getElementById("carousel-one");

            i++;
        }

        return new Res("200",arrayList);

结果集实体类
