How to set HTTP header in RESTEasy 3.0 client framework (with ResteasyClientBuilder and ResteasyWebTarget)?

I'm trying to figure out how to set HTTP headers similar to what was explained here:

However, I want to use RESTeasy 3.0 functionality (ResteasyClientBuilder and ResteasyWebtarget) and not the deprecated ProxyFactory, as explained here:

And just to clarify, I also do not want to set the header(s) on every request / don't want them to be passed to the client, I'd like them to be set on ResteasyClientBuilder/ResteasyWebtarget level if possible.

Found a solution.

The trick is to register a ClientRequestFilter with the ResteasyClient (line #2 of the method below):

public Resource getResource(Credentials credentials) {
    ResteasyClient client = new ResteasyClientBuilder().build();
    client.register(new AuthHeadersRequestFilter(credentials));
    return client.target(restServiceRoot).proxy(Resource.class);
}

And then have your request filter do something like:

public class AuthHeadersRequestFilter implements ClientRequestFilter {

    private final String authToken;

    public AuthHeadersRequestFilter(Credentials credentials) {
        authToken = credentials.getAuthorizationHeader();
    }

    @Override
    public void filter(ClientRequestContext requestContext) throws IOException {
        requestContext.getHeaders().add("Authorization", authToken);
    }
}
