Json编码的关联数组（来自PHP）在Java中转换为json对象

Question

I have a json encoded associative array which contains a combination of map and list this is done in PHP.

This json string is transferred to java via web service call

How do I handle this json string to get the original associative array data. I know java doesn't support associative array. But any alternatives are appreciated.

Sample json string:

Use javax.jason

try (JsonReader jsonReader = Json.createReader(new StringReader(jsonString))) {
    JsonObject object = jsonReader.readObject();
    System.out.println(object);
}
