有时候调取接口的，返回一个HTML页面，我们后台拿到HTML页面字符串，需要解析发给前台使用，比如一个地址，或者HTML字符串里面的相关内容。

获取jsoup的jar包，可以去maven仓库中下载，下载地址：

解析案例如下：

 @Test
    public void test5() {
        String html = "<html><head><title>302 Moved Temporarily</title></head>\n" +
                "<body bgcolor=\"#FFFFFF\">\n" +
                "<p>This document you requested has moved \n" +
                "temporarily.</p>\n" +
                "<p>It's now at <a href=\"https://pay.ceibs.edu/paycenter/dopay/selectprovider?u=4f54d017-8605-4c64-8367-96a38257a92e\">https://pay.ceibs.edu/paycenter/dopay/selectprovider?u=4f54d017-8605-4c64-8367-96a38257a92e</a>.</p>\n" +
                "</body></html>";
        Document doc = Jsoup.parse(html);
        System.out.println(doc); // 输出带标签的html文档
        System.out.println("---------------------\n"+doc.text()); // 输出内容
        Elements element = doc.getElementsByTag("a");
        System.out.println("---------------------\n"+element.text());
    }

结果如下：

<html>
 <head>
  <title>302 Moved Temporarily</title>
 </head> 
 <body bgcolor="#FFFFFF"> 
  <p>This document you requested has moved temporarily.</p> 
  <p>It's now at <a href="https://pay.ceibs.edu/paycenter/dopay/selectprovider?u=4f54d017-8605-4c64-8367-96a38257a92e">https://pay.ceibs.edu/paycenter/dopay/selectprovider?u=4f54d017-8605-4c64-8367-96a38257a92e</a>.</p> 
 </body>
</html>
---------------------
302 Moved Temporarily This document you requested has moved temporarily. It's now at https://pay.ceibs.edu/paycenter/dopay/selectprovider?u=4f54d017-8605-4c64-8367-96a38257a92e.
