Neal Hu commented on CXF-6307:
------------------------------
Correct the signature to
public Object readFrom(Class<Object > type,
Type type1,
Annotation[] antns,
MediaType mt, MultivaluedMap<String, String> mm,
InputStream in) throws IOException, WebApplicationException
I guess that add media type checking in the isReadable will not impact the
result of Reader sorting(depends on @Consume), right?
According to the spec, we may need mix the default and custom providers and
sort. If they all match the Java type and media type is the same then choose
custom provider. Any comment please let me know.

> Key: CXF-6307
> URL: https://issues.apache.org/jira/browse/CXF-6307
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.0.3
> Environment: Windows
> Reporter: Neal Hu
> Fix For: 3.0.5
>
>
> This is a CTS testcase, the resource class is like this:
> @POST
> @Path("boolean")
> public Boolean postBoolean(Boolean bool) {
> if(bool){
> throw new WebApplicationException(Status.NOT_ACCEPTABLE);
> }
> return false;
> }
> The application provided provider is like this:
> public class MyReader implements MessageBodyReader<Boolean> {
> @Override
> public boolean isReadable(Class<?> type, Type type1, Annotation[] antns,
> MediaType mt) {
> return type== Boolean.class;
> }
> @Override
> public Object readFrom(Class<Object > type,
> Type type1,
> Annotation[] antns,
> MediaType mt, MultivaluedMap<String, String> mm,
> InputStream in) throws IOException,
> WebApplicationException {
> return Boolean.valueOf("true");
> }
> }
> The request
> Content-Type:text/plain
> Accept:text/plain
> Method:POST
> Body:false
> According to jsr339 section 4.2.4 Standard Entity Providers
> java.lang.Boolean, java.lang.Character, java.lang.Number Only for text/plain.
> Corresponding primitive types supported via boxing/unboxing conversion.
> An implementation MUST support application-provided entity providers and MUST
> use those in preference to its own pre-packaged providers when either could
> handle the same request. More precisely, step 4 in Section 4.2.1 and step 5
> in Section 4.2.2 MUST prefer application-provided over pre-packaged entity
> providers.
> 4.2.1 Message Body Reader
> 3. Select the set of MessageBodyReader classes that support the media type of
> the request, see Section
> 4.2.3.
> 4. Iterate through the selected MessageBodyReader classes and, utilizing the
> isReadable method of
> each, choose a MessageBodyReader provider that supports the desired Java type.
> It says the entity providers should be sorted by media type firstly then(the
> media type is the same) on Section 4.2.1 and step 5 in Section 4.2.2 MUST
> prefer application-provided over pre-packaged entity providers. So
> org.apache.cxf.jaxrs.provider.PrimitiveTextProvider should be selected as its
> media type MUST be text/plain and the application provider's media type is
> */*.(x/y>x/*>*/*)
> So at this point the CTS expected response code is 200 instead of 406, the
> application provided provider should not be chosen.
