Root name of JSON data format

See original GitHub issue

This is

public class Person {
    private String name;
    private double height;
    private int age;
    private Date date;
    private Address address;
        //normal constructor

This is my main class:

public class AppJson {
    public static void main(String[] arg) throws JsonGenerationException,
            JsonMappingException, IOException {
        Address a = new Address("Jln Koli", "90121", "Vila", "Belgium");
        Person p = new Person("Ali Bin Baba", new Date(), 90.0, 12, a);

        Json json = new Json(p);


  "name" : "Ali Bin Baba",
  "age" : 12,
  "date" : "06-12-2014",
  "Address" : {
    "postcode" : "90121",
    "city" : "Vila",
    "state" : "Belgium",
    "street" : "Jln Koli"

But, the output I want is like this:

  "Person": {
    "name": "Ali Bin Baba",
    "age": "12",
    "date": "06-12-2014",
    "Address": {
      "postcode": "90121",
      "city": "Vila",
      "state": "Belgium",
      "street": "Jln Koli"

Did you know, which part is wrong??

Two ways to go; either use something like:

public class PersonList extends ArrayList<Person> { }

to specify root name for your List subtype.

Or use method in ObjectWriter to use whatever name you want for object:

ObjectWriter w = ...;

You are not using “withRootName(“Person”)” in there.

And from now on, let’s use mailing lists for questions, discussions. Issue trackers are for bugs.
