Vedran Pavic commented on CXF-6869:
-----------------------------------

Hey Sergey,

The thing that's causing the issue with your sample is it's unnecessary 
complexity - you have two Spring Boot main classes in your project, 
{{SampleRestApplication}} and {{SampleScanRestApplication}}. It does not matter 
that you explicitly mark one of them as main-class in your {{pom.xml}} - the 
other is still in the same package tree and it's a valid {{@Configuration}} 
class (by virtue of {{@SpringBootApplication}} being composite annotation 
which, among other things, includes {{@Configuration}} annotation) so it's 
going to get picked up by Spring's application context component scanning 
mechanisms.

In practice, this means that when you designate {{SampleRestApplication}} as 
your Spring Boot main-class the {{@Import(SpringComponentScanServer.class)}} 
from {{SampleScanRestApplication}} will still be in effect.

This kind of usage is actually not considered the best practice in Spring Boot 
world.

I encourage you to reuse the samples I've prepared as much as possible - they 
are simple and provide best practices without additional complexity.

> I've recently authored a PR in Spring Boot to add support for 
> auto-configuration of {{CXFServlet}} and default CXF's configuration:
> https://github.com/spring-projects/spring-boot/pull/5659
> The PR was closed with "won't fix" resolution since Boot team are unwilling 
> to add CXF as a dependency to the project. Instead a 3rd party starter was 
> suggested.
> The concept of a 3rd party starter is generally encouraged for technologies 
> that don't have first-class support in projects from Spring portfolio. Such 
> 3rd party starters are listed here:
> https://github.com/spring-projects/spring-boot/blob/master/spring-boot-starters/README.adoc
> If CXF team is interested, I'm willing to port my PR to CXF.
> Note that the original PR was focused around JAX-WS support, but can be 
> easily expanded to include JAX-RS support as well.
