Mapping fields for Input Types with different names between schema and Java Object

[gaganis]

Is there a way to map fields for input types? I have been unable to find how to do this neither in the documentation or by searching the web.

For example to be able to map full_name in the schema to fullName in the java object:

input CreateUserInput {
    full_name: String
}

to

public class CreateUserInput {
    private String fullName;  // Must match GraphQL schema

    public String getFullName() {
        return fullName;
    }

    public void setFullName(String fullName) {
        this.fullName = fullName;
    }
}

We are migrating our app from https://github.com/graphql-java-kickstart and we used to do that using jackson@JsonProperty.

Any pointers would be greatly appreciated

Thanks

We used to decode through Jackson, but it involves serializing the argument map to JSON first, which can cause issues with scalar value formatting, see #122. We now use our own mechanism, the GraphQlArgumentBinder. Currently, it does not support this kind of mapping. We could consider some sort of naming strategy, or a Function to map keys from the argument map.

Thanks for you reply

In my POV something like this would make a lot of sense to me. Not sure if this would fit any of your suggestions @rstoyanchev

public class CreateUserInput {

    @ShemaMapping(field="full_name")
    private String fullName;  // Must match GraphQL schema
    ...
}
