首先 要用浏览器分析网页代码

得到想要的信息

引入依赖

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

 

Document document = Jsoup.connect("url")
        .ignoreContentType(true)
        .userAgent(new DateList().ua[**])  // 伪造用户
        .data("p", s.getName())            // 请求参数  get直接拼写到链接后面
        .post();  　　　　　　　　　　　　　　　// 请求方式  post


// 获取 id 元素 
Element id = document.getElementById("id");

// 获取 class 元素
Elements class= document.getElementsByClass("class");

// 获取 li 标签  (其它标签一样)
Elements li = element.getElementsByTag("li");

// 以上元素获取完 全部都可以接着向下遍历
for (Element element : class) { 
　　....
}

 

// 获取元素的值
String span = element.getElementsByTag("span").text();

// 获取a标签的链接
String url = element1.getElementsByTag("a").attr("abs:href");

//获取元素值截取
String lastime = byClass.getElementsByTag("script").toString().substring(24, 34);

 

以上基本够用了
根据自己的网页解析分析使用

数据：

public static class DateList {
    String[] ua = {"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0",
