使用com.alibaba.fastjson.JSON将这个json数据转化，使其可以在java中去除对应值{"addvcd":"","areacd":"","stcd":"","rvcd":"","zdycd":"","zdqh_geojson":{}}

以下是使用com.alibaba.fastjson.JSON将json数据转化的示例代码：

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;

public class JsonTest {
    public static void main(String[] args) {
        String jsonStr = "{\"addvcd\":\"\",\"areacd\":\"\",\"stcd\":\"\",\"rvcd\":\"\",\"zdycd\":\"\",\"zdqh_geojson\":{}}";
        JSONObject jsonObject = JSON.parseObject(jsonStr);
        String addvcd = jsonObject.getString("addvcd");
        String areacd = jsonObject.getString("areacd");
        String stcd = jsonObject.getString("stcd");
        String rvcd = jsonObject.getString("rvcd");
        String zdycd = jsonObject.getString("zdycd");
        JSONObject zdqh_geojson = jsonObject.getJSONObject("zdqh_geojson");
        System.out.println(addvcd);
        System.out.println(areacd);
        System.out.println(stcd);
        System.out.println(rvcd);
        System.out.println(zdycd);
        System.out.println(zdqh_geojson);
    }
}

输出结果为：
