I'm writing a RESTful web service in Jersey 2. I want to support the Gzip encoding for the responses. Following this answer, I enabled the org.glassfish.jersey.server.filter.EncodingFilter in my ResourceConfig class.

public class MyWebService extends ResourceConfig 
 public MyWebService() 
 register(EncodingFilter.class);
 register(GZipEncoder.class);
 register(DeflateEncoder.class);
 

On my resource class, I'm returning a javax.ws.rs.core.Response object.

@GET
@Path("api/configs") 
public Response listConfigs() throws Exception 
 List<UserConfig> configs = configService.getAll();
 return Response.ok().entity(configs).build();

Now when I hit this api, I get a response but the response headers do not contain a Content-Encoding header, rather it contains Transfer-Encoding: chunked.

Request:

> GET /api/configs HTTP/1.1
> Accept-Encoding: gzip

Response:

> HTTP/1.1 200 
> Transfer-Encoding: chunked
* Received 14.8 KB chunk
* Received 504 B chunk
* Received 15.2 KB chunk
* Received 506 B chunk
* Received 15.1 KB chunk
* Received 514 B chunk

There is no Content-Encoding: gzip header in the response, nor there is any Content-Length header.

I'm using Jersey 2.27 on Tomcat 9.

Is there any other configuration I'm missing? How do I get these two headers and get the response as gzip compressed rather than receiving chunked response?

Edit: I have noticed that when I send large files ( > 1000 KB) I get both the Content-Encoding: gzip and Transfer-Encoding: chunked headers.

  I don't think MyWebService is being picked up by the container. Are you loading it from web.xml like shown in this answer? --- Try putting a breakpoint on the first register(...) call to see if it's being executed. If it is, then put a breakpoint at the beginning of filter(...) in the class EncodingFilter, and step through to see any it's not applying the gzip encoding.

Whether to use Transfer-Encoding or Content-Length is entirely the container's discretion. It depends on the allowed buffer size.

If the container has to set the Content-Length header, it has to know the length of the compressed response beforehand, therefore, the container has to buffer the entire response in the memory.

In case of Jersey, the content length buffer size is defined by ServerProperties.OUTBOUND_CONTENT_LENGTH_BUFFER. By default, this is 8192 bytes.

You can easily increase this from your MyWebService class:

public class MyWebService extends ResourceConfig 
 public MyWebService() 
 register(EncodingFilter.class);
 register(GZipEncoder.class);
 register(DeflateEncoder.class);

 ...

 property(ServerProperties.OUTBOUND_CONTENT_LENGTH_BUFFER, 32768);

 

Hope this helps.
