---------------------------------
Summary: Jsonp interceptors do not work with GZIPOutInterceptor
Key: CXF-5240
URL: https://issues.apache.org/jira/browse/CXF-5240
Project: CXF
Issue Type: Bug
Components: JAX-RS, Transports
Affects Versions: 2.5.9
Reporter: Vadim Beilin
Jsonp support via Jsonp(In,PreStream,PostStream)Interceptor (as described in
http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-JSONWithPadding%28JSONP%29)
conflicts with GZIPOutInterceptor.
With a very simple test application request
"http://localhost:7543/12?_jsonp=abc"; without Gzip results in the following
response
bq. abc(24);
With Gzip:
bq. abc();24
Apparent reason is that the method
org.apache.cxf.jaxrs.provider.jsonp.AbstractJsonpOutInterceptor.writeValue(Message,
String) writes directly to the response output stream. When the method is
changed to write to {{message.getContent(OutputStream.class)}}, responses with
and without Gzip interceptor become the same "abc(24);", as expected.
------------------------
Service code:
{code}
package test.cxf.jsonp;
import javax.ws.rs.*;
@Path("/") @Produces("application/json")
public class Service {
@GET @Path("{id}") public int find(@PathParam("id") int id) {
return id * 2;
}
}
{code}
Configuration (with Gzip)
{code}
<jaxrs:server id="jsonp" address="http://localhost:7543/";>
<jaxrs:serviceBeans>
<ref bean="serviceBean" />
</jaxrs:serviceBeans>
<jaxrs:inInterceptors>
<bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpInInterceptor"/>
<bean class="org.apache.cxf.transport.common.gzip.GZIPInInterceptor"/>
</jaxrs:inInterceptors>
<jaxrs:outInterceptors>
<bean
class="org.apache.cxf.jaxrs.provider.jsonp.JsonpPreStreamInterceptor"/>
<bean
class="org.apache.cxf.jaxrs.provider.jsonp.JsonpPostStreamInterceptor"/>
<bean class="org.apache.cxf.transport.common.gzip.GZIPOutInterceptor"/>
</jaxrs:outInterceptors>
</jaxrs:server>
