https://stackoverflow.com/questions/42446990/parse-html-table-to-json-using-jsoup-in-java

maven：

<!--将html转换为Map-->
<dependency>
   <groupId>org.jsoup</groupId>
   <artifactId>jsoup</artifactId>
   <version>1.10.3</version>
</dependency>

实现:

public String TableToJson(String url) throws JSONException { Document doc = Jsoup.connect(url).get(); JSONObject jsonParentObject = new JSONObject(); //JSONArray list = new JSONArray(); for (Element table : doc.select("table")) { for (Element row : table.select("tr")) { JSONObject jsonObject = new JSONObject(); Elements tds = row.select("td"); String Name = tds.get(0).text(); String Group = tds.get(1).text(); String Code = tds.get(2).text(); String Lesson = tds.get(3).text(); String Day1 = tds.get(4).text(); String Day2 = tds.get(5).text(); String Day3= tds.get(6).text(); jsonObject.put("Group", Group); jsonObject.put("Code", Code); jsonObject.put("Lesson", Lesson); jsonObject.put("Day1", Day1); jsonObject.put("Day2", Day2); jsonObject.put("Day3", Day3); jsonParentObject.put(Name,jsonObject); } } return jsonParentObject.toString(); }
