How to use Spring Autowired in a custom cxf interceptor? - web-services

Question

i seem to run into a small issue when using #Autowired into a custom cxf interceptor.
My use case is that i want to log soap messages and send these using AMQP to another system. This process works for normal services etc.
But whatever i do, the needed properties do not get autowired and stay null.
I checked the Spring DI log and the context is scanned and pickedup, so what am i missing?
Is this even possible in CXF interceptors?
#Component
public class LogInInterceptor extends AbstractSoapInterceptor {
private #Value("#{rabbitMQProperties['rabbitmq.binding.log.soap']}")
String binding;
#Autowired
AmqpTemplate amqpTemplate;
public LogInInterceptor() {
super(Phase.RECEIVE);
}
#Override
public void handleMessage(SoapMessage soapMessage) throws Fault {
logIt(soapMessage);
}
private void logIt(SoapMessage message) throws Fault {
// rest of the code omitted...!!!
amqpTemplate.convertAndSend(binding, buffer.toString());
}
}

Answer 1

You can't mix #InInterceptors (a CXF annotation) and #Component (a Spring annotation). That will create two separate instances of your interceptor: the one whose dependencies are getting injected by Spring, and one created by CXF. (You are providing class names in the #InInterceptors annotation, not a bean ID, so CXF has no way of knowing that you already created an instance in the Spring context.)
Remove the #InInterceptors annotation and, in addition to the component scan:
<context:component-scan base-package="org.example.config"/>
You also need something like this in your application context:
<jaxws:endpoint id="myWebService" address="/MyWebService">
<jaxws:inInterceptors>
<ref bean="myInInterceptor" />
</jaxws:inInterceptors>
</jaxws:endpoint>

I know this is an old question, but Jonathan W's answer helped me and I would like to add to it.
This is how I got custom interceptors and #Autowired to work with Spring Boot 1.3.1:
http://cxf.apache.org/docs/jax-ws-configuration.html
import java.util.Arrays;
import javax.jws.WebService;
import org.apache.cxf.Bus;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
#Configuration
#EnableAutoConfiguration
#ImportResource({ "classpath:META-INF/cxf/cxf.xml" })
public class Application extends SpringBootServletInitializer {
#Autowired
private ApplicationContext applicationContext;
#Autowired
private MyInterceptor myInterceptor;
#Autowired
private HelloWorldImpl helloWorldImpl;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
// Replaces the need for web.xml
#Bean
public ServletRegistrationBean servletRegistrationBean(ApplicationContext context) {
return new ServletRegistrationBean(new CXFServlet(), "/api/*");
}
// Replaces cxf-servlet.xml
#Bean
// <jaxws:endpoint id="helloWorld" implementor="demo.spring.service.HelloWorldImpl" address="/HelloWorld"/>
public EndpointImpl helloService() {
Bus bus = (Bus) applicationContext.getBean(Bus.DEFAULT_BUS_ID);
EndpointImpl endpoint = new EndpointImpl(bus, helloWorldImpl);
// Set interceptors here
endpoint.setInInterceptors(Arrays.asList(myInterceptor));
endpoint.publish("/hello");
return endpoint;
}
// Used when deploying to a standalone servlet container, i.e. tomcat
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
// Web service endpoint
#WebService(endpointInterface = "demo.spring.service.HelloWorld")
//#InInterceptors not defined here
public static class HelloWorldImpl {
}
public static class MyInterceptor extends LoggingInInterceptor {
// #Autowired works here
}
}
