Chapter 26. GZIP Compression/Decompression

RESTEasy has automatic GZIP decompression support. If the client framework or a JAX-RS service receives a message body with a Content-Encoding of gzip, the message will be automatically decompressed. The client framework also sets the Accept-Encoding header to gzip, deflate automatically.

RESTEasy also supports automatic compression. If a request or response with a Content-Encoding header of gzip is sent or received, RESTEasy performs the compression. You can use the @org.jboss.resteasy.annotation.GZIP annotation if you do not want to set each Content-Encoding manually.

@Path("/")
public interface MyProxy {

   @Consumes("application/xml")
   @PUT
   public void put(@GZIP Order order);
}

Here, the order message body is tagged for GZIP compression. You can use the same annotation to tag server responses:

@Path("/")
public class MyService {

   @GET
   @Produces("application/xml")
   @GZIP
   public String getData() {...}
}
