How to enable gzip compression for content encoding with Jersey (JAX-RS 2.0) client?

I have a Java application that uses the Jersey implementation of JAX-RS 2.0 and I want to enable gzip compression on the client side. The server has it enabled and I have verified that by looking in Chrome at the "Size/Content" in the Developer Tools for the specific URL the client is using.

I see a lot of information and documentation floating around the web about setting the HTTP Headers with filters and decoding response bodies with interceptors and I cannot decipher what I actually need to code in the client.

I have this code:

private synchronized void initialize() {
    Client client = ClientBuilder.newClient();
    client.register(new HttpBasicAuthFilter(username, password));
    WebTarget targetBase = client.target(getBaseUrl());
    ...
}

What should I add to enable compression?

managed to do it with:

private synchronized void initialize() {
    Client client = ClientBuilder.newClient();
    client.register(new HttpBasicAuthFilter(username, password));
    client.register(GZipEncoder.class);
    client.register(EncodingFilter.class);
    WebTarget targetBase = client.target(getBaseUrl());
    ...
}

Pretty much the same as @Jason, but EncodingFilter detects the GzipEncoder for me.
