Subject [jira] [Commented] (CXF-5360) Resource classes are selected incorrectly
Date Mon, 28 Oct 2013 15:06:33 GMT

    [ https://issues.apache.org/jira/browse/CXF-5360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13806833#comment-13806833
] 

Ivan Bondarenko commented on CXF-5360:
--------------------------------------

Approximately this code (regardless of CXF styling, possible bugs etc) must be added to ClassResourceInfo
comparison:
{code}OperationResourceInfo ori1 = null, ori2 = null;
try {
	ori1 = JAXRSUtils.findTargetMethod(cri1, message, httpMethod, values, requestContentType,
acceptContentTypes, false);
}catch (Throwable e) {
}
try {
	ori2 = JAXRSUtils.findTargetMethod(cri2, message, httpMethod, values, requestContentType,
acceptContentTypes, false);
}catch (Throwable e) {
}
if (ori1 != ori2) {
	return (ori1 == null) ? 1 : -1;
}{code}

>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 2.7.7
>            Reporter: Ivan Bondarenko
>            Priority: Blocker

> The problem: the resource is selected incorrectly when multiple classes can 'visually'
handle request. For example if we have two classes
> {code}@Path("/") class Foo {
>   @GET @Path("bar") public String bar() { return "bar"; }
> }
> @Path("/") class Real {
>   @GET @Path("hello") public String hello() { return "hello"; }
> }{code}
> and their instances are registered in this order (e.g. in jaxrs:serviceBeans), when I
GET the "/hello" path, the Foo will be selected, while it is not even able to handle this
request.
> The starting point to investigate the problem is org.apache.cxf.jaxrs.utils.JAXRSUtils.selectResourceClass(List<ClassResourceInfo>,
String, MultivaluedMap<String, String>, Message), where 'candidateList' variable is
filled incorrectly. Unfortunately I'm not so familiar with CXF code to provide a patch, but
resource class must be selected basing on full class description (all methods and annotations
must be taken into account).
> Why this is a problem: except obvious reason (unexpected behavior), this bug disallows
to make REST service modular. For example we may want to provide different feature sets for
different servers. Right now it is not possible to implement.
