ObjectMapper - String JSON to java object with sublevel arrays

I am trying to de-serialize the json string to objects, and facing an issue where I have array of objects in sub level. I looked into the below stackoverflow links where they have designed one class and classes with in that for each sub level; and used List<> for array of data. I have used the same but have seprate classes for each object (separate java files)

How to use Jackson to deserialise an array of objects

Let me give you a vision of my code:

JSON for Person details

{
"name" : "abcd",
"age" : 30,
"addressList" : {
   "count" : 2,
   "data" : [
     {
      "state" : "NY",
      "city" : "Bronx"
     },
     {
      "state" : "NJ",
      "city" : "Chestnut"
     }
   ]
 }
}

Classes

public class Person {
    private String name;
    private int age;
    private AddressList addressList;

    public Person() { }

    //getters and setters
}

public class AddressList {
    private int count;
    private List<Address> data;

    public AddressList() { }

    //getters and setters
}

public class Address {
    private String state, city;

    public Address() { }

    //getters and setters
}

In my main class, doing like below:

ObjectMapper mapper = new ObjectMapper();
Defect defect = mapper.readValue(jsonString, Person.class);

Now, All the values are loading properly except the address list. Even I tried Address[] instead of List<Address> in AddressList.java but no luck. Can anyone give me some ideas on this or what could be the mistake. Thanks in advance.
