Servlet doPost obtain JSON

Question

I would like to retrieve the following information from a JSON:

{
    "list_folder": {
            "accounts": [
                        "dbid:Aapamskfpano1-l2_12oKKn123o1pk23"
                        ]
    },
    "delta": {
            "users": [
                      12321512
            ]
    }

}

I need both the accounts array and users array. This JSON is in the body.

How I can obtain and parse this?

but you mean retrieve the JSON in the controller or in the client side by javascript? — cralfaro, Jul 18 '17 at 08:52
[`ServletRequest::getReader`](http://docs.oracle.com/javaee/7/api/javax/servlet/ServletRequest.html#getReader--) is what you're looking for. — Flown, Jul 18 '17 at 08:56
I want to retrieve the JSON in the doPost method in the server side. — Lechucico, Jul 18 '17 at 08:57

Obtaining this JSON and parsing it are two separate questions that both have been addressed on SO. — Turtle, Jul 18 '17 at 09:03

JSONObject json = new JSONObject(jsonString);
MyObject myObject = new Gson().fromJson(jsonString, MyObject.class);
