Apache的CXF现在几乎成了Java领域构建Web Service的首选类库，并且它也确实简单易用，下面就通过几篇系列文章做一下简单介绍。
当然首先想到的当然还是那个Hello World示例。这个系列文章中用到的例子都是基于Maven构建的工程，下面是我的pom.xml文件内容

package com.googlecode.garbagecan.cxfstudy.helloworld;import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;@WebServicepublic interface HelloWorld { @WebMethod @WebResult String sayHi(@WebParam String text);}package com.googlecode.garbagecan.cxfstudy.helloworld;public class HelloWorldImpl implements HelloWorld { public String sayHi(String name) { String msg = "Hello " + name + "!"; return msg; }}package com.googlecode.garbagecan.cxfstudy.helloworld;import org.apache.cxf.jaxws.JaxWsServerFactoryBean;// http://localhost:9000/HelloWorld?wsdlpublic class Server { public static void main(String[] args) throws Exception { JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean(); factory.setServiceClass(HelloWorldImpl.class); factory.setAddress("http://localhost:9000/ws/HelloWorld"); factory.create(); System.out.println("Server start..."); Thread.sleep(60 * 1000); System.out.println("Server exit..."); System.exit(0); }}package com.googlecode.garbagecan.cxfstudy.helloworld;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.setServiceClass(HelloWorld.class); factory.setAddress("http://localhost:9000/ws/HelloWorld"); HelloWorld helloworld = (HelloWorld) factory.create(); System.out.println(helloworld.sayHi("kongxx")); System.exit(0); }}首先运行Server类来启动Web Service服务，然后访问http://localhost:9000/ws/HelloWorld?wsdl地址来确定web service启动正确。
运行Client测试类，会在命令行输出Hello kongxx!的message。
