Error in the JAX-RS implementation for matching method types to Accept Header
-----------------------------------------------------------------------------
Key: CXF-1431
URL: https://issues.apache.org/jira/browse/CXF-1431
Project: CXF
Issue Type: Bug
Components: REST
Affects Versions: 2.1
Reporter: Barry Fitzgerald
Fix For: 2.1
Consider the following scenario:
I have a resource with 2 methods:
@HttpMethod("GET")
@UriTemplate("/users/{id}")
@ProduceMime("text/xml")
public Response getUser(@UriParam("id") String id) throws Exception { ....}
@HttpMethod("GET")
@UriTemplate("/users/{id}")
@ProduceMime("application/json")
public Response getUserJSON(@UriParam("id") String id) throws Exception { ....}
If I then send a request to /users/24 with Accept headers of "text/xml, */*"
one would expect the "text/xml" method to be invoked. However in the CXF
implementation the application/json one is invoked. Suggest changing the
algorithm to:
1. Sort the Accept header according to the W3 standards
2. Iterate through the accept header list. For each one:
1. Find all matching methods
2. If there is only one method return this and break out of the accept
header loop
3. If there are multiple methods sort these methods using consume mime
and produce mime. Then return the first
