Simon Gerber commented on CXF-5066:
-----------------------------------
My sincere apologies - reviewing my test case the actual cause of my issue was
mixing and matching parameter and method annotations.
I.e.
{noformat}
@Path("example")
public interface Example {
@Path("{reference}")
ExampleResponse get(@PathParam("reference") String reference);
}
public class ExampleImpl implements Example {
@Override
public ExampleResponse get(@PathParam("reference") String reference) { //
... }
}
{noformat}
Eclipse's 'extract interface' refactor leaves the annotations behind on the
implementation class - and I forgot to strip the PathParam annotations. At the
time I was absolutely convinced I saw this issue on a method that only had the
Path annotation - but I cannot replicate now either.

> Key: CXF-5066
> URL: https://issues.apache.org/jira/browse/CXF-5066
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.7.5
> Reporter: Simon Gerber
> Priority: Minor
>
> Consider an annotated interface and implementation as follows
> {noformat}
> @Path("example")
> public interface Example {
>
> @GET
> ExampleResponse get();
> }
> public class ExampleImpl implements Example {
> @Override
> public ExampleResponse get() { // ... }
> }
> {noformat}
> The documentation states that 'most JAX-RS annotations can be inherited from
> the superclass or interface'. However in the above example CXF will reject
> this resource as ResourceUtils.createClassResourceInfo() fails to find any
> dispatcher methods.
> The reason for this is that AnnotationUtils.doGetAnnotatedMethod() returns
> the concrete class method because it has an Override annotation on it.
> Therefore it does not find the method annotation.
> The workaround is to remove the Override annotation - however since many IDEs
> (such as Eclipse) are configured to add this by default it could be
> considered a case where user expectations will not be met. This caveat was
> not documented anywhere and it required debugging into the CXF source code to
> isolate the issue.
