JAX-RS (wrongly?) complaining about no resource methods for ExceptionMappers.
-----------------------------------------------------------------------------
Key: CXF-3248
URL: https://issues.apache.org/jira/browse/CXF-3248
Project: CXF
Issue Type: Improvement
Components: JAX-RS
Affects Versions: 2.3.2
Reporter: Glen Mazza
Priority: Minor
Example 7-1 of the JAX-RS book samples (see
https://issues.apache.org/jira/browse/CXF-3247) is returning a unclear error
message when it processes the following ExceptionMapper:
@Provider
public class NotFoundExceptionMapper implements
ExceptionMapper<NotFoundException>
{
public Response toResponse(NotFoundException exception)
{
return Response.status(Response.Status.NOT_FOUND)
.entity(exception.getMessage())
.type("text/plain").build();
}
}
This is the error message it's returning:
WARNING: No resource methods have been found for resource class
com.restfully.shop.services.NotFoundExceptionMapper
I'm not sure why an exception mapper needs to have resource methods, or what a
"resource method" is for that matter. I think this error is appropriate for
root resources only and not exception mappers, if so, this message should be
suppressed for exception mappers. OTOH, if this warning does have meaning for
exception mappers, could it be made clearer for newbies/novices?
Note this example has other bugs with it, not related to this problem
(https://issues.jboss.org/browse/RESTEASY-495).
To duplicate, download and extract RESTEasy and make the pom.xml and web.xml
changes all described in https://issues.apache.org/jira/browse/CXF-3247. Then
just run mvn clean install and you'll see the above error message.
