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

下面来看看HelloWorld的具体例子。
1.创建HelloWorld 接口类
package com.googlecode.garbagecan.cxfstudy.helloworld;  
import javax.jws.WebMethod;  
import javax.jws.WebParam;  
import javax.jws.WebResult;  
import javax.jws.WebService;  
@WebService  
public interface HelloWorld {  
@WebMethod  
@WebResult String sayHi(@WebParam String text);  
}  


2.创建HelloWorld实现类
package com.googlecode.garbagecan.cxfstudy.helloworld;  
public class HelloWorldImpl implements HelloWorld {  
public String sayHi(String name) {  
String msg = "Hello " + name + "!";  
return msg;  
}  
}  

3.创建Server端测试类
package com.googlecode.garbagecan.cxfstudy.helloworld;  
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;  
// http://localhost:9000/HelloWorld?wsdl  
public 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);  
}  
}  

4.创建Client端测试类
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);  
}  
}  


5.测试
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。
