**一.开发环境**

我的开发环境是：

MyEclipse 10

Apache cxf-2.3.0 相关jar包下载地址： [ http://www.apache.org/dist/cxf/2.3.0/][http_www.apache.org_dist_cxf_2.3.0]

**二.开发步骤**

**创建Server**

**1.**新建一个Java工程CxfDemo，并添加apache cfx-2.3.0的j相关ar包至lib文件夹中,然后建个com.study包。Java工程效果截图：

在com.study包里面创建HelloWorld接口

代码如下

package com.study;
    
    import javax.jws.WebMethod;
    import javax.jws.WebParam;
    import javax.jws.WebResult;
    import javax.jws.WebService;
    
    @WebService
    public interface HelloWorld {
    	@WebMethod
    	@WebResult String say(@WebParam String context);
    
    }

再创建一个类实现HelloWorld接口

package com.study;
    
    public class HelloImpl implements HelloWorld {
    	
    	public String say(String context) {
    		// TODO Auto-generated method stub
    		String msg = "Hello " + context + "!";
    		return msg;
    	}
    
    <span style="font-family:SimHei;">}
    </span>

再创建一个Server端测试类

package com.study;
    
    import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
    
    public class Server {
    	public static void main(String[] args) throws Exception {
    		JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
    		factory.setServiceClass(HelloImpl.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);
    
    	}
    
    }

再创建一个Client端测试类

package com.study;
    
    import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
    
    public class Client {
    
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
    		factory.setServiceClass(HelloWorld.class);
    		factory.setAddress("http://localhost:9000/ws/HelloWorld");
    		HelloWorld helloworld = (HelloWorld) factory.create();
    		System.out.println(helloworld.say("zhouzhigang"));
    		System.exit(0);
    
    	}
    
    }

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 zhouzhigang!的message。
