David J. M. Karlsen commented on CXF-5448:
------------------------------------------
Did anything happen to this? I think this is even more applicable now as Spring
Boot /@Configuration is spreading. I see the boot support in
http://cxf.apache.org/docs/springboot.html - but when you are trying to fit
JAX-WS and JAX-RS services into the same app, under separate prefixes and buses
it won't work - so making the programmatic approach easier would be a great
benefit. In my case I have in one app:
- inbound JAX-RS (on one bus, with some distinct Features, some overlapping
with with other bus'es)
- inbound JAX-WS (on another bus, some distinct Features, some common with
other bus'es)
- outbound JAX-WS clients (yet another bus, with yet distinct Features, and
also some overlapping ones with the others)

> Hi,
> as per dev mailing list thread started by me
> http://mail-archives.apache.org/mod_mbox/cxf-dev/201312.mbox/%3c1386597934463-5737561.p...@n5.nabble.com%3e
> I would like to share my solution to get rid of XML file with CXF services
> definition.
> My case is rather simple (read: uncomplete) as I just want to automatically
> register in CXF @WebService and @WebServiceProvider annotated classes, so
> that they are exposed via CXFServlet.
> The end developer just needs to annotate her services with e.g. @WebService
> annotation and also needs to add a following Spring configuration
> (application code):
> {code:title=SampleAppConfig.java|borderStyle=solid}
> import javax.jws.WebService;
> import javax.xml.ws.WebServiceProvider;
> import org.springframework.context.annotation.ComponentScan;
> import org.springframework.context.annotation.ComponentScan.Filter;
> import org.springframework.context.annotation.Configuration;
> import org.springframework.context.annotation.Import;
> @Configuration
> @Import(JaxWsConfig.class)
> @ComponentScan(value = { "package filters" },
> includeFilters = {
> @Filter(WebService.class),
> @Filter(WebServiceProvider.class)
> })
> public class SampleAppConfig {
> }
> {code}
> where JaxWsConfig is a reference to CXF Spring configuration (it should be a
> part of CXF):
> {code:title=JaxWsConfig.java|borderStyle=solid}
> @Configuration
> @ImportResource({
> "classpath:META-INF/cxf/cxf.xml",
> "classpath:META-INF/cxf/cxf-servlet.xml"
> })
> public class JaxWsConfig {
> }
> {code}
> The crucial part is Spring bean post processor (that should be also a part of
> CXF distribution):
> {code:title=JaxWsBeanPostProcessor.java|borderStyle=solid}
> @Named
> public class JaxWsBeanPostProcessor implements BeanPostProcessor {
> @Inject
> ListableBeanFactory beanFactory;
>
> @Override
> public Object postProcessBeforeInitialization(Object bean, String beanName)
> throws BeansException {
> return bean;
> }
> @Override
> public Object postProcessAfterInitialization(Object bean, String beanName)
> throws BeansException {
> if (isWebService(bean)) {
> Bus bus = beanFactory.getBean(Bus.DEFAULT_BUS_ID, Bus.class);
> SpringEndpointImpl endpoint = new SpringEndpointImpl(bus, bean);
> // capitalization is just a nice feature - totally optional
> endpoint.setAddress("/" + StringUtils.capitalize(beanName));
> // adds ALL features registered / discovered by Spring
> Map<String, AbstractFeature> featureMap =
> beanFactory.getBeansOfType(AbstractFeature.class);
> endpoint.getFeatures().addAll(featureMap.values());
> endpoint.publish();
> }
>
> return bean;
> }
> boolean isWebService(Object bean) {
> Class<?> beanClass = bean.getClass();
> return beanClass.getAnnotation(WebService.class) != null
> || beanClass.getAnnotation(WebServiceProvider.class) != null;
> }
> }
> {code}
> And then if you also want to configure / inject your features using CDI
> (Spring) you do stuff like this (application code):
> {code:title=MyFeature.java|borderStyle=solid}
> @Named
> public class MyFeature extends AbstractFeature {
>
> @Inject
> MyInInterceptor inInterceptor;
> @Inject
> MyOutInterceptor outInterceptor;
> @Override
> protected void initializeProvider(InterceptorProvider provider, Bus bus) {
> bus.getInInterceptors().add(inInterceptor);
> bus.getOutInterceptors().add(outInterceptor);
> }
> {code}
> Does that make sense?
> Please note that my implementation is simplified but works for me. You should
> probably add all other possible customizations in JaxWsBeanPostProcessor
> class.
