一，导入依赖

org.jsoup

jsoup

1.10.3

org.apache.httpcomponents

httpclient

二，编写demo类

注意不要导错包了,是org.jsoup.nodes下面的

package com.taotao.entity;

import org.apache.http.HttpEntity;

import org.apache.http.client.methods.CloseableHttpResponse;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.HttpClients;

import org.apache.http.util.EntityUtils;

import org.jsoup.Jsoup;

import org.jsoup.nodes.Document;

import org.jsoup.nodes.Element;

import org.jsoup.select.Elements;

import java.io.IOException;

/**

public class intefaceTest {

public static void main(String[] args) throws IOException {

CloseableHttpClient httpClient = HttpClients.createDefault();//创建httpClient

HttpGet httpGet = new HttpGet("http://www.cnblogs.com/");//创建httpget实例

CloseableHttpResponse response = httpClient.execute(httpGet);//执行get请求

HttpEntity entity = response.getEntity();//获取返回实体

String content = EntityUtils.toString(entity,"utf-8");//网页内容

response.close();//关闭流和释放系统资源

Jsoup.parse(content);

Document doc = Jsoup.parse(content);//解析网页得到文档对象

Elements elements = doc.getElementsByTag("title");//获取tag是title的所有dom文档

Element element = elements.get(0);//获取第一个元素

String title = element.text(); //.html是返回html

System.out.println("网页标题："+title);

Element element1 = doc.getElementById("site_nav_top");//获取id=site_nav_top标签

String str = element1.text();

System.out.println("str:"+str);

}

}
