Apache cxf using annotations and integration with Spring

Today I will show you how you can create a webservice using Apache CXF version 2.2.1. I will be building this webservice on top of my previous application.

Create a interface AirlineManager to expose methods over webservice. The create method takes airline code and name to create a Airline record in database. Annotation @WebService tells that this is a interface for webservice.

package com.travel;

import javax.jws.WebService;

@WebService
public interface AirlineManager {
    public void create(String code, String name);
}

Implement the above webservice interface. We are using AirlineDao created in earlier post. Notice the @WebService(endpointInterface = "com.travel.AirlineManager") which tells that this implementation is for AirlineManager interface.

package com.travel;

import com.travel.dao.AirlineDao;
import javax.jws.WebService;

@WebService(endpointInterface = "com.travel.AirlineManager")
public class AirlineManagerImpl implements AirlineManager {
    private AirlineDao airlineDao;

    public AirlineManagerImpl(AirlineDao aAirlineDao) {
        airlineDao = aAirlineDao;
    }

    @Override
    public void create(String code, String name) {
        airlineDao.create(code, name);
    }
}

Add this in the spring-context.xml. Here we are importing some cxf beans, defining bean AirlineManagerImpl and creating airlineManagerService webservice.

 <import resource="classpath:META-INF/cxf/cxf.xml" />
 <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
 <import resource="classpath:META-INF/cxf/cxf-extension-http-jetty.xml"/>
 <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

 <bean id="airlineManager" class="com.kaleconsultants.travel.AirlineManagerImpl">
  <constructor-arg><ref bean="airlineDao"/></constructor-arg>
 </bean>

 <jaxws:endpoint id="airlineManagerService" implementor="#airlineManager" address="/AirlineManagerService" />

Add this in your web.xml.

 <servlet>
  <servlet-name>CXFServlet</servlet-name>
  <display-name>CXF Servlet</display-name>
  <servlet-class>
   org.apache.cxf.transport.servlet.CXFServlet
  </servlet-class>
  <load-on-startup>1</load-on-startup>
 </servlet>
  
 <servlet-mapping>
  <servlet-name>CXFServlet</servlet-name>
  <url-pattern>/*</url-pattern>
 </servlet-mapping>

Deploy the application in tomcat and your webservice is ready. You can check the wsdl http://host:port/travel/AirlineManagerService?wsdl.

To test the webservice, you need to create a client. You can use wsdl2java available in the bin directory of cxf.

Execute this command, this will generate the wsdl stubs.
wsdl2java http://host:port/travel/AirlineManagerService?wsdl

Write a client like this and there you go.......

package com.travel;

public class ClientTest {
    public static void main(String[] args) {
        AirlineManagerImplService service = new AirlineManagerImplService();
        AirlineManager airlineManager = service.getAirlineManagerImplPort();
        airlineManager.create("IC", "Indian");
    }
}
