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

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.

In my example (with JAX RS 2.x) and Jersey where multipart is being used, none of the above worked but this did:

Client client = ClientBuilder.newBuilder()
            .register(EncodingFilter.class)
            .register(GZipEncoder.class)
            .property(ClientProperties.USE_ENCODING, "gzip")
            .register(MultiPartFeature.class)
            .register(LoggingFilter.class)
            .build();

Essentially same as the above answers but had to add that one property for "gzip".

Modify to look like:

private synchronized void initialize() {
    Client client = ClientBuilder.newClient();
    client.register(new HttpBasicAuthFilter(username, password));
    client.register(GZipEncoder.class);
    WebTarget targetBase = client.target(getBaseUrl());
    ...
    // new lines here:
    Invocation.Builder request = targetBase.request(MEDIA_TYPE);
    request.header(HttpHeaders.ACCEPT_ENCODING, "gzip");
    ...
}

In this example, there are some fields and methods being referenced that I don't include in the example (such as MEDIA_TYPE), you'll have to figure those out yourself. Should be pretty straight forward.

I verified this worked by analyzing the response headers and monitoring the application network usage. I got a 10:1 compression ratio according to the network usage checks I did. That seems about right, yay!
