Apache CXF jax-rs with Spring Boot: how to configure interceptors automatically

Question

I have CXF Rest Api with using Spring Boot, so here's my application.properties:

cxf.path=/
cxf.jaxrs.server.address=/api
cxf.jaxrs.component-scan=true
cxf.jaxrs.classes-scan-packages=org.apache.cxf.jaxrs.swagger,org.apache.cxf.metrics

My endpoints are annotated as @Component, but the problem is I have not only the components or providers, but also ExceptionMappers, In/Out/Fault Interceptors.

Now I'm wondering if it can be configured via properties file as well.

And I know possible solution (don't propose me this one):

@Bean
public Server rsServer() {
  final JAXRSServerFactoryBean endpoint = new JAXRSServerFactoryBean();

  endpoint.setInInterceptors(Arrays.<Interceptor<? extends Message>>asList(
    interceptor1,
    interceptor2,
    interceptor3
  ));

  endpoint.setOutInterceptors(Arrays.<Interceptor<? extends Message>>asList(out1));
  endpoint.setOutFaultInterceptors(Arrays.<Interceptor<? extends Message>>asList(out1));

  endpoint.setProviders(Arrays.asList(
    provider1(),
    provider2()
  ));

  endpoint.setBus(bus);

  endpoint.setAddress("/api");

  endpoint.setServiceBeans(Arrays.asList(
    endpoint1,
    endpoint2,
    ...,
    endpointN
  ));

  endpoint.setFeatures(Arrays.asList(new Swagger2Feature()));
  return endpoint.create();
}

This is not cool at all as far as so many features can be configured automatically and now for some additional configs I have to configure everything manually.

It kills the purpose of using Spring Boot at all. So.. any suggestions?

Please check CxfAutoConfiguration.java and AbstractSpringComponentScanServer.java, you need not create server bean manually, AutoConfiguration does for you, you need to just set property cxf.jaxrs.component-scan=true, it will add all spring beans annotated @Path and @Provider to server instance. If you have custom interceptors make it bean by adding @Component and @Provider(//with type). For Swagger and Metrics generally I create bean using @Bean, please check the example here
