Beanparam without fields is not supported #47545
Description
Describe the bug
If I use a class as a @BeanParam, which has no fields annotated as jax-rs parameters (e.g. QueryParam), I get an exception on start. see below.
@Path("/hello")
public class GreetingResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String hello(@BeanParam Params params) {
return "Hello from Quarkus REST";
}
public static class Params {
//@RestQuery
//String matchCode;
}
}
Expected behavior
The exception itself states
No annotations found on fields at 'org.acme.GreetingResource$Params'. Annotations like @QueryParam should be used in fields, not in methods.
However, the jakarta rest spec states (Appendix A):
https://jakarta.ee/specifications/restful-ws/4.0/jakarta-restful-ws-spec-4.0.pdf
So this is behaviour which (unintentionally?) differs from the spec
No matter what decision is taken here, the log message itself is confusing. The second sentence does not seem to have any relevance to the first sentence?
