CXF和Axis2是兩個比較流行的webService框架，接下來我會寫幾篇部落格簡單介紹如何使用這兩種框架。首先，先簡單介紹一下CXF的使用。

CXF釋出webService有多種方法，這裡我介紹三種：

1、不使用Spring，CXF自動釋出webService

2、不使用Spring，CXF手動釋出webService

3、使用Spring + CXF釋出webService

這篇部落格以例項介紹第一種方法——不使用Spring，CXF自動釋出webService。

服務端：

目錄結構如下：

IHelloWorldServer程式碼：

<span style="font-family:Microsoft YaHei;font-size:18px;">package com.test.server;

public interface IHelloWorldServer {
	public String sayHello(String username); 
}</span>
 

<span style="font-family:Microsoft YaHei;font-size:18px;">package com.test.server;

public class HelloWorldServerImp implements IHelloWorldServer {

	@Override
	public String sayHello(String username) {
		return username+" : HelloWorld";
	}
}</span>

WebServlet程式碼：

<span style="font-family:Microsoft YaHei;font-size:18px;">package com.test.server;

import javax.servlet.ServletConfig;

import org.apache.cxf.Bus;
import org.apache.cxf.BusFactory;
import org.apache.cxf.frontend.ServerFactoryBean;
import org.apache.cxf.transport.servlet.CXFNonSpringServlet;

public class WebServlet extends CXFNonSpringServlet {
//	private static final String SERVICE_SUFFIX = "";
	private static final long serialVersionUID = 1L;  
	  
    @Override  
    protected void loadBus(ServletConfig servletConfig) {  
        super.loadBus(servletConfig);  
        
        Bus bus = getBus();  
        BusFactory.setDefaultBus(bus);  
        HelloWorldServerImp helloWorld = new HelloWorldServerImp();//實現類  
       
        ServerFactoryBean serverFactoryBean = new ServerFactoryBean(); //server工廠  
        serverFactoryBean.setServiceClass(IHelloWorldServer.class);// 介面類  
        serverFactoryBean.setAddress("/helloWorld"); //服務請求路徑  
        serverFactoryBean.setServiceBean(helloWorld);  
        serverFactoryBean.create();  
    }  
}</span>

客戶端：

HelloWorldClient程式碼：

<span style="font-family:Microsoft YaHei;font-size:18px;">package com.test.client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

public class HelloWorldClient {
	public static void main(String[] args) {
		JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
		org.apache.cxf.endpoint.Client client = dcf.createClient("http://localhost:8080/cxf_demo_noSpring_1/ws/helloWorld?wsdl");
                Object[] objects;
		try {
			objects = client.invoke("sayHello", "haitao");
			//輸出呼叫結果
			System.out.println(objects[0].toString());
		} catch (Exception e) {
			e.printStackTrace();
		} 
	}
}
</span>

至此，第一種方式介紹完畢，接下來的部落格我會繼續介紹其他方法。
