下面是我用来提取数据的实用程序的代码片段。 下面是示例JSON，我必须在其中提取“其他/车辆/属性”的值，但是却收到错误消息。
请提出我需要添加到实用程序的哪些内容？ 我需要获取其他/车辆/属性的值。 请建议我需要在Utility中进行哪些更改，以便嵌套属性也可以从JSON中获取。
public class TestUtil {
public static JSONObject responsejson;
public static String getValueByJPath(JSONObject responsejson, String jpath){
Object obj = responsejson;
for(String s : jpath.split("/"))
if(!s.isEmpty())
if(!(s.contains("[") || s.contains("]")))
obj = ((JSONObject) obj).get(s);
else if(s.contains("[") || s.contains("]"))
obj = ((JSONArray) ((JSONObject) obj).get(s.split("\\[")[0])).get(Integer.parseInt(s.split("\\[")[1].replace("]", "")));
return obj.toString();
}
}
JSON格式：
