Boon JSON - Change Field Name for Object Deserialization

Question

I am using Boon JSON and I'd like to change the name of a field on a class that is being generated from JSON.

I just want to change

{"first_name": "Cristine", "last_name": "McVie"}

So it maps to the Java fields:

String firstName;
String lastName;

I've already got everything working (ie, if I use camel-case in the JSON, the object is created properly.

I've tried the @JsonPropery and (based on the suggestion in comments) the @Named annotations on the class, like so:

public class Person {
    @Named("first_name")
    private String firstName;
    @Named("first_name")
    public String getFirstName() {
        return firstName;
    }
    @Named("first_name")
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

---

Just for edification, this is why I didn't see @JsonProperty working at first. This app is running in Eclipse debug mode, and I was trusting Eclipse to redeploy the updated code, but adding an annotation is apparently NOT enough to trigger the update. Had to restart the app to pick it up.

You need to add either a SerializedName annotation (like GSON) or aJsonProperty annotation (like Jackson) to the fields, like so:

import org.boon.json.annotations.JsonProperty;
import org.boon.json.annotations.SerializedName;

public static class Person {
    @SerializedName("first_name")
    String firstName;

    @JsonProperty("last_name")
    String lastName;
}

You can see another example in the documentation.
