POST request from Ember js (Ember-cli) to Spring Boot application

This is the JSON format that I get from Ember js when I make a POST request. I use RestAdapter to make an API call. { "programmer": { "firstName": "Janaki", "lastName": "Rathinam" } } But my spring boot would accept only

{
    "Programmer": {
      "id": 1,
      "firstName": "Maha",
      "lastName": "Shankar"
    }
}

How do I resolve this mismatching JSONs so that I can make a POST call from emberjs. Will adding Serializer resolve my issue? If yes how do I write a serializer for this?
