------------------------------
Summary: MessageBodyReader and MessageBodyWritter should follow
different sorting rule
Key: CXF-6412
URL: https://issues.apache.org/jira/browse/CXF-6412
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.0.5, 2.7.15, 3.0.4
Reporter: iris ding
According to JSR-339 spec, section 4.2.1 and 4.2.2, we need follow different
sorting rule for MessageBodyReader and MessageBodyWritter:
For MessageBodyReader, it is:
<h3> 2. Identify the Java type of the parameter whose value will be mapped
from the entity body. Section 3.7</h3>
describes how the Java method is chosen.
<h3>3. Select the set of MessageBodyReader classes that support the media
type of the request, see Section 4.2.3. </h3>
For MessageBodyWritter, it is:
<h3>4. Sort the selected MessageBodyWriter providers with a primary key of
generic type where providers whose generic type is the nearest superclass of
the object class are sorted first and a secondary key of media type (see
Section 4.2.3).</h3>
But in our implementation, we use the same sorting rule:
1. compareClasses() ->compareSortedMediaTypes()
This caused an issue in https://issues.apache.org/jira/browse/CXF-6380.
Actually we need to adjust the MessageBodyReader sorting method.
