After JAVAEE8 published , now you can use the new JAVAEE API JSON-B (JSR367)

Maven dependency :

    javax.json.bind
    javax.json.bind-api
    1.0



    org.eclipse
    yasson
    1.0



    org.glassfish
    javax.json
    1.1

Here is some code snapshot :

Jsonb jsonb = JsonbBuilder.create();
// Two important API : toJson fromJson
String result = jsonb.toJson(listaDePontos);

JSON-P is also updated to 1.1 and more easy to use. JSON-P 1.1 (JSR374)

Maven dependency :

    javax.json
    javax.json-api
    1.1



    org.glassfish
    javax.json
    1.1

Here is the runnable code snapshot :

String data = "{\"name\":\"Json\","
                + "\"age\": 29,"
                + " \"phoneNumber\": [10000,12000],"
                + "\"address\": \"test\"}";
        JsonObject original = Json.createReader(new StringReader(data)).readObject();
        /**getValue*/
        JsonPointer pAge = Json.createPointer("/age");
        JsonValue v = pAge.getValue(original);
        System.out.println("age is " + v.toString());
        JsonPointer pPhone = Json.createPointer("/phoneNumber/1");
        System.out.println("phoneNumber 2 is " + pPhone.getValue(original).toString());
