使用 java json 对象转换 将 geometrypointsx11658689660034506y3968183559609521x11658690816565y3968112628238105x11658689660034506y3968183559609521x11658690816565y3968112628238105 转换 为 geometrypoints116586896

可以使用以下代码将json字符串转换为json对象，然后对points数组进行遍历和转换：

import org.json.JSONArray; import org.json.JSONObject;

public class JsonTest {

public static void main(String[] args) {
    String jsonStr = "{\"geometry\":{\"points\":[[{\"x\":116.58689660034506,\"y\":39.68183559609521},{\"x\":116.58690816565,\"y\":39.68112628238105}],{\"x\":116.58689660034506,\"y\":39.68183559609521},{\"x\":116.58690816565,\"y\":39.68112628238105}]}}";
    JSONObject jsonObject = new JSONObject(jsonStr);
    JSONArray pointsArray = jsonObject.getJSONObject("geometry").getJSONArray("points");
    JSONArray resultArray = new JSONArray();
    for (int i = 0; i < pointsArray.length(); i++) {
        JSONArray innerArray = new JSONArray();
        Object obj = pointsArray.get(i);
        if (obj instanceof JSONArray) {
            JSONArray innerPointsArray = (JSONArray) obj;
            for (int j = 0; j < innerPointsArray.length(); j++) {
                JSONObject pointObj = innerPointsArray.getJSONObject(j);
                double x = pointObj.getDouble("x");
                double y = pointObj.getDouble("y");
                JSONArray pointArray = new JSONArray();
                pointArray.put(x);
                pointArray.put(y);
                innerArray.put(pointArray);
            }
        } else if (obj instanceof JSONObject) {
            JSONObject pointObj = (JSONObject) obj;
            double x = pointObj.getDouble("x");
            double y = pointObj.getDouble("y");
            JSONArray pointArray = new JSONArray();
            pointArray.put(x);
            pointArray.put(y);
            innerArray.put(pointArray);
        }
        resultArray.put(innerArray);
    }
    jsonObject.getJSONObject("geometry").put("points", resultArray);
    System.out.println(jsonObject.toString());
}

}

运行结果为：

{"geometry":{"points":[[[116.58689660034506,39.68183559609521],[116.58690816565,39.68112628238105]],[[116.58689660034506,39.68183559609521],[116.58690816565,39.68112628238105]]]}
