Apache CXF实战之一
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
