Sergey Beryozkin commented on CXF-5448:
---------------------------------------
So I wonder, should @Bean annotation be used instead then, which is what is
used in the code contributed to the JAX-RS frontend ? There we use no Filter
(whose purpose is obvious) and it still works, and if we do then we can achieve
the optimization, i.e, the ApplicationContext will only list the matched beans ?

> Spring integration via @Configuration & @ComponentScan annotations

> Key: CXF-5448
> URL: https://issues.apache.org/jira/browse/CXF-5448
> Project: CXF
> Issue Type: Improvement
> Components: Integration
> Affects Versions: 2.6.11
> Reporter: Przemyslaw Bielicki
> Priority: Minor
>
> Hi,
> as per dev mailing list thread started by me
> http://mail-archives.apache.org/mod_mbox/cxf-dev/201312.mbox/%[email protected]%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.
