Sergey Beryozkin commented on CXF-4782:
---------------------------------------
I think you can simply write a basic CXF interceptor which will sit at any
stage before or at the one used by JAXRSInInterceptor and replace "_type" with
"format" by updating Message.QUERY_STRING on the message; and also update
RequestPreprocessor by getting it from the message:
{code:java}
ProviderFactory providerFactory = ProviderFactory.getInstance(message);
RequestPreprocessor rp = providerFactory.getRequestPreprocessor();
{code}
Hope it will do it
> Cannot easily override the Accept content type

> Key: CXF-4782
> URL: https://issues.apache.org/jira/browse/CXF-4782
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.7.2
> Reporter: Jason Chaffee
>
> I need to add the ability to override the Accept header using a query
> parameter. I know CXF supports "_type", but there are two problems with the
> way that is implemented that won't work for us. 1) We need to parameter name
> to be "format" instead of "_type" and currently this is not configurable. 2)
> We need to be able to pass in a map of special type that we would like to
> map. This would added to the SHORTCUTS.
> Since the current RequestPreProcessor doesn't allow for either one of those,
> I decided to write a JAXRS Filter/RequestHandler. The problem I found is
> that the JAXRSInInterceptor has already looked up the acceptContentType
> before my RequestHandler.handleRequest() method is called. Thus, I am unable
> to override it using this approach.
> Ideally, the fix would be to simply make them configurable in the
> RequestPreProcessor. However, I am not quite sure how that would be done
> since this is not a class that is managed/configured in the IoC/DI container.
>
> Another approach would be to call the RequestHandlers before resolving the
> acceptContentType.
