SpringBoot @SpringBootApplication.exclude not working properly

I created my own autoconfiguration to auto-register services to CXF:

@Configuration
@ImportResource({ "classpath:META-INF/cxf/cxf.xml" })
public class ServiceConfig {

  @Inject
  private ApplicationContext applicationContext;

  @Inject
  private ObjectMapperFactory objectMapperFactory;

  @Bean
  public ServletRegistrationBean cxfServletRegistration() {
    return new ServletRegistrationBean(new CXFServlet(), "/services/*");
  }

  @Bean
  public JacksonJsonProvider jacksonJsonProvider() {
    return new JacksonJsonProvider(this.objectMapperFactory.createInstance());
  }

  @Bean
  public Server jaxRsServer() {
    List<Object> restServiceBeans = new ArrayList<>(this.applicationContext.getBeansWithAnnotation(Path.class).values());
    List<Object> providerBeans = new ArrayList<>(
        this.applicationContext.getBeansWithAnnotation(Provider.class).values());

    JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();
    factory.setBus(this.applicationContext.getBean(SpringBus.class));
    factory.setAddress("/rest");
    factory.setServiceBeans(restServiceBeans);
    factory.setProviders(providerBeans);

    return factory.create();
  }
}

Next I added this as META-INF/spring.factories:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=io.oasp.module.rest.ServiceConfig

Works like a charm if there are services available... However my spring tests in the same module stopped working. I am using a dummy @SpringBootApplication class to configure the tests. Now I can see that ServiceConfig.jaxRsServer() is called in the test what lets the application context fail to startup. I added an exclude on ServiceConfig but still I am getting the same error.

@SpringBootApplication(exclude = { ServiceConfig.class })
public class SpringBootTestConfig {

I also observed the same problem for regular spring boot apps (without spring-test). It seems as if @SpringBootApplication.exclude is ignored in my context. Spring will still instantiate the excluded ServiceConfig and call all @Bean methods what fails in that case. All I want is to tell spring to stop instantiating my ServiceConfig and IMHO that is exactly what @SpringBootApplication.exclude should be for. In case I am using @Profile I can prevent spring from instantiating the ServiceConfig but this is not a real solution.

Is your ServiceConfig class in sub-package of SpringBootTestConfig? If so it might be getting loaded due to @ComponentScan. Perhaps try replacing @SpringBootApplication with @Configuration and @EnableAutoConfiguration (and leave off @ComponentScan)

Jep. Thanks for the explanation. You saved my day.

I added this to SpringBootTestConfig and now it is working:

@ComponentScan(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ServiceConfig.class) )

For users not understanding the internals of spring the behavior of "exclude" is somewhat confusing. However, feel free to close this issue as there is a easy workaround.
