Spring Boot + Apache CXF. Publish endpoints with annotations only - spring

Question

According to official Apache CXF documentation we create SOAP services in spring in such way:
Configuration class
import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.xml.ws.Endpoint;
#Configuration
public class WebServiceConfiguration {
private static final String BINDING_URI = "http://www.w3.org/2003/05/soap/bindings/HTTP/";
#Bean
public ServletRegistrationBean<CXFServlet> disServlet() {
return new ServletRegistrationBean<>(new CXFServlet(), "/soap-api/*");
}
#Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
SpringBus bus = new SpringBus();
bus.setProperty("org.apache.cxf.stax.maxTextLength", 1024 * 1024 * 1024);
return bus;
}
#Bean
public Endpoint userServiceEndpoint(UserService userService) {
EndpointImpl endpoint = new EndpointImpl(springBus(), userService);
endpoint.setBindingUri(BINDING_URI);
endpoint.publish("/users");
return endpoint;
}
}
Generated from WSDL SOAP interface:
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.3.2
* Generated source version: 2.2
*
*/
#WebService(name = "UserServiceSoap", targetNamespace = "http://User.no/webservices/")
#XmlSeeAlso({ObjectFactory.class})
public interface UserServiceSoap {
#WebMethod(operationName = "GetUser", action = "http://User.no/webservices/GetUser")
#WebResult(name = "GetUserResult", targetNamespace = "http://User.no/webservices/")
#RequestWrapper(localName = "UserServiceSoap", targetNamespace = "http://User.no/webservices/", className = "no.user.webservices.generated.UserServiceSoap")
#ResponseWrapper(localName = "UserServiceSoapResponse", targetNamespace = "http://User.no/webservices/", className = "no.user.webservices.generated.UserServiceSoapResponse")
public String getUser(#WebParam(name = "username", targetNamespace = "http://User.no/webservices/") String username);
}
Service implementation:
#Service
#WebService(
endpointInterface = "no.altinn.webservices.generated.UserServiceSoap",
serviceName = "UserServiceSoapService",
targetNamespace = "http://User.no/webservices/",
portName = "UserServiceSoapPort"
)
#BindingType("http://java.sun.com/xml/ns/jaxws/2003/05/soap/bindings/HTTP/")
public class UserService implements UserServiceSoap {
#Override
public String getUser(String requestUsername) {
//logic
}
}
What do I want?
Is there any already implemented way to publish SOAP endpoint without creating bean in the spring configuration. I want to do it with annotation on service implementation, for example (#SoapEndpoint):
#Service
#SoapEndpoint(bindingUri = "http://www.w3.org/2003/05/soap/bindings/HTTP/",
publish = "/users")
#WebService(
endpointInterface = "no.altinn.webservices.generated.UserServiceSoap",
serviceName = "UserServiceSoapService",
targetNamespace = "http://User.no/webservices/",
portName = "UserServiceSoapPort"
)
#BindingType("http://java.sun.com/xml/ns/jaxws/2003/05/soap/bindings/HTTP/")
public class UserService implements UserServiceSoap {
#Override
public String getUser(String requestUsername) {
//logic
}
}

Workaround:
Create empty interface named SoapService and #SoapEndpoint and initialize endpoints manually
SoapService interface:
public interface SoapService {
}
#SoapEndpoint interface:
#Target(ElementType.TYPE)
#Retention(RetentionPolicy.RUNTIME)
#Documented
#Inherited
public #interface SoapEndpoint {
String bindingUri() default "http://www.w3.org/2003/05/soap/bindings/HTTP/";
String publish();
}
Initialize endpoints manually
#Configuration
public class WebServiceConfiguration {
private static final String BINDING_URI = "http://www.w3.org/2003/05/soap/bindings/HTTP/";
#Autowired
private List<SoapService> endpoints;
#Bean
public ServletRegistrationBean<CXFServlet> disServlet() {
return new ServletRegistrationBean<>(new CXFServlet(), "/soap-api/*");
}
#Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
SpringBus bus = new SpringBus();
bus.setProperty("org.apache.cxf.stax.maxTextLength", 1024 * 1024 * 1024);
return bus;
}
#PostConstruct
public void init() {
for (SoapService bean : endpoints) {
if (bean.getClass().getAnnotation(SoapEndpoint.class) == null) {
throw new IllegalArgumentException("Missed #SoapEndpoint for " + bean.getClass().getName());
}
EndpointImpl endpoint = new EndpointImpl(springBus(), bean);
endpoint.setBindingUri(BINDING_URI);
endpoint.publish(bean.getClass().getAnnotation(SoapEndpoint.class).publish());
}
}
}
Add SoapService into you implementation classes
#Service
#SoapEndpoint(publish = "/users")
#WebService(endpointInterface = "no.altinn.webservices.generated.UserServiceSoap", serviceName = "UserServiceSoapService", targetNamespace = "http://User.no/webservices/", portName = "UserServiceSoapPort")
#BindingType("http://java.sun.com/xml/ns/jaxws/2003/05/soap/bindings/HTTP/")
public class UserService implements UserServiceSoap, SoapService {
#Override
public String getUser(String requestUsername) {
//logic
}
}
--- Result (I've added OrganitionService which implements OrganizationServiceSoap) ---
