Resteasy has automatic GZIP decompression support. If the client framework or a JAX-RS service receives a messagy body with a Content-Encoding of "gzip", it will automatically decompress it. The client framework automatically sets the Accept-Encoding header to be "gzip, deflate". So you do not have to set this header yourself.
Resteasy also supports automatic compression. If the client framework is sending a request or the server is sending a response with the Content-Encoding header set to "gzip", Resteasy will do the compression. So that you do not have to set the Content-Encoding header directly, you can use the @org.jboss.resteasy.annotation.GZIP annotation.
@Path("/")
public interface MyProxy {
@Consumes("application/xml")
@PUT
public void put(@GZIP Order order);
}
In the above example, we tag the outgoing message body, order, to be gzip compressed. You can use the same annotation to tag server responses
@Path("/")
public class MyService {
@GET
@Produces("application/xml")
@GZIP
public String getData() {...}
}
