Apache CXF 第一篇：HelloWorld
1、开发环境：JDK 1.6，Spring 2.0，LZ使用Apache CXF 2.6.2 版本。因为使用Spring 2.0故不能使用CXF with Spring的方式配置WebServices服务，故采用传统的Servlet方式。2、所需CXFJAR，在CXF下载包中均存在

3、服务端接口：
package com.vtradex.training.server.cxf.helloworld;
import javax.jws.WebParam;
import javax.jws.WebService;
import com.vtradex.training.server.cxf.WsConstants;
/**
*
* @author <a href="mailto:brofe.pan@gmail.com">潘宁波</a>
* @version $Revision: v1.0 $Date: 2012-8-31 $
*/
@WebService(name = "HelloWorldService", targetNamespace = WsConstants.NS)
public interface HelloWorldService {
String say(@WebParam(name="message") String message);
}
4、服务端实现类：
package com.vtradex.training.server.cxf.helloworld.impl;
import javax.jws.WebService;
import com.vtradex.training.server.cxf.WsConstants;
import com.vtradex.training.server.cxf.helloworld.HelloWorldService;
/**
* WebService服务端实现类.
*
* serviceName与portName属性指明WSDL中的名称, endpointInterface属性指向Interface定义类.
*
* @author <a href="mailto:brofe.pan@gmail.com">潘宁波</a>
* @version $Revision: v1.0 $Date: 2012-8-31 $
*/
@WebService(serviceName = "HelloWorldService", portName = "HelloWorldServicePort", endpointInterface = "com.vtradex.training.server.cxf.helloworld.HelloWorldService", targetNamespace = WsConstants.NS)
public class HelloWorldServiceImpl implements HelloWorldService {
@Override
public String say(String message) {
return "Hello, " + message;
}
}
5、常量定义类：
package com.vtradex.training.server.cxf;
/**
* WebService常量定义.
*
* @author <a href="mailto:brofe.pan@gmail.com">潘宁波</a>
* @version $Revision: v1.0 $Date: 2012-8-31 $
*/
public class WsConstants {
/**项目内统一的NameSpace定义, for SOAP.*/
public static final String NS = "http://thorn4.training.vtradex.com";
/**项目内统一的XML charset定义, for REST*/
public static final String CHARSET = ";charset=UTF-8";
}
6、发布服务的 Servlet
package com.vtradex.training.server.cxf.helloworld;
import javax.servlet.ServletConfig;
import javax.xml.ws.Endpoint;
import org.apache.cxf.transport.servlet.CXFNonSpringServlet;
import com.vtradex.training.server.cxf.helloworld.impl.HelloWorldServiceImpl;
/**
*
*
* @author <a href="mailto:brofe.pan@gmail.com">潘宁波</a>
* @version $Revision: v1.0 $Date: 2012-9-1 $
*/
public class WsServlet extends CXFNonSpringServlet {
private static final long serialVersionUID = 1L;
@Override
protected void loadBus(ServletConfig sc) {
super.loadBus(sc);
System.out.println("Starting CXF Web Services... HelloWorldServices");
//: http://localhost:8088/training/ws/helloWorldService?wsdl
Endpoint.publish("/helloWorldService", new HelloWorldServiceImpl());
}
}
7、web.xml
<servlet>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>com.vtradex.training.server.cxf.helloworld.WsServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/ws/*</url-pattern>
</servlet-mapping>
8、启动Web服务，在浏览器中即可查看WSDL
9、CXF 客户端调用：
package com.vtradex.training.server.cxf.helloworld;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
/**
*
*
* @author <a href="mailto:brofe.pan@gmail.com">潘宁波</a>
* @version $Revision: v1.0 $Date: 2012-9-1 $
*/
public class WsClient {
public static void main(String[] args) {
/**
* 这种方式要求客户端必须依赖服务端
*/
//JaxWsProxyFactoryBean bean = new JaxWsProxyFactoryBean();
// bean.setServiceClass(HelloWorldService.class);
// bean.setAddress("http://localhost:8088/training/ws/helloWorldService");
// HelloWorldService helloWorldService = (HelloWorldService)bean.create();
// String result = helloWorldService.say("Brofe");
// System.out.println(result);
/**
* 通过WSDL调用
*/
JaxWsDynamicClientFactory clientFactory = JaxWsDynamicClientFactory.newInstance();
Client client = clientFactory.createClient("http://localhost:8088/training/ws/helloWorldService?wsdl");
client.getInInterceptors().add(new LoggingInInterceptor());
client.getOutInterceptors().add(new LoggingOutInterceptor());
Object[] result;
try {
result = client.invoke("say", "brofe");
System.out.println(result);
} catch (Exception e) {
e.printStackTrace();
}
}
}
