Apache CXF 第一篇：HelloWorld

阅读更多

1、开发环境：JDK 1.6，Spring 2.0，LZ使用Apache CXF 2.6.2 版本。因为使用Spring 2.0故不能使用CXF with Spring的方式配置WebServices服务，故采用传统的Servlet方式。

2、所需CXFJAR，在CXF下载包中均存在

                true
            
        

3、服务端接口：

package com.vtradex.training.server.cxf.helloworld;

import javax.jws.WebParam;
import javax.jws.WebService;

import com.vtradex.training.server.cxf.WsConstants;

/**
 * 
 * @author 潘宁波
 * @version $Revision: v1.0 $Date: 2012-8-31 $
 */
@WebService(name = "HelloWorldService", targetNamespace = WsConstants.NS)
public interface HelloWorldService {
	
	String say(@WebParam(name="message") String message);
	
}

4、服务端实现类：

package com.vtradex.training.server.cxf.helloworld.impl;

import javax.jws.WebService;

import com.vtradex.training.server.cxf.WsConstants;
import com.vtradex.training.server.cxf.helloworld.HelloWorldService;

/**
 * WebService服务端实现类.
 * 
 * serviceName与portName属性指明WSDL中的名称, endpointInterface属性指向Interface定义类.
 * 
 * @author 潘宁波
 * @version $Revision: v1.0 $Date: 2012-8-31 $
 */
@WebService(serviceName = "HelloWorldService", portName = "HelloWorldServicePort", endpointInterface = "com.vtradex.training.server.cxf.helloworld.HelloWorldService", targetNamespace = WsConstants.NS)
public class HelloWorldServiceImpl implements HelloWorldService {

	@Override
	public String say(String message) {
		return "Hello, " + message;
	}

}

5、常量定义类：

package com.vtradex.training.server.cxf;

/**
 * WebService常量定义.
 * 
 * @author 潘宁波
 * @version $Revision: v1.0 $Date: 2012-8-31 $
 */
public class WsConstants {
	
	/**项目内统一的NameSpace定义, for SOAP.*/
	public static final String NS = "http://thorn4.training.vtradex.com";

	/**项目内统一的XML charset定义, for REST*/
	public static final String CHARSET = ";charset=UTF-8";
}

6、发布服务的 Servlet

package com.vtradex.training.server.cxf.helloworld;

import javax.servlet.ServletConfig;
import javax.xml.ws.Endpoint;

import org.apache.cxf.transport.servlet.CXFNonSpringServlet;

import com.vtradex.training.server.cxf.helloworld.impl.HelloWorldServiceImpl;

/**
 * 
 * 
 * @author 潘宁波
 * @version $Revision: v1.0 $Date: 2012-9-1 $
 */
public class WsServlet extends CXFNonSpringServlet {
	
	private static final long serialVersionUID = 1L;

	@Override
	protected void loadBus(ServletConfig sc) {
		super.loadBus(sc);
		
		System.out.println("Starting CXF Web Services... HelloWorldServices");
		
		//: http://localhost:8088/training/ws/helloWorldService?wsdl
		Endpoint.publish("/helloWorldService", new HelloWorldServiceImpl()); 
	}
}

7、web.xml

		CXFServlet
		com.vtradex.training.server.cxf.helloworld.WsServlet
		2
	
	
	
		CXFServlet
		/ws/*
	

8、启动Web服务，在浏览器中即可查看WSDL

9、CXF 客户端调用：

package com.vtradex.training.server.cxf.helloworld;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

/**
 * 
 * 
 * @author 潘宁波
 * @version $Revision: v1.0 $Date: 2012-9-1 $
 */
public class WsClient {
	public static void main(String[] args) {
		
		/**
		 * 这种方式要求客户端必须依赖服务端
		 */
//		JaxWsProxyFactoryBean bean = new JaxWsProxyFactoryBean();  
//        bean.setServiceClass(HelloWorldService.class);  
//        bean.setAddress("http://localhost:8088/training/ws/helloWorldService");  
//        HelloWorldService helloWorldService = (HelloWorldService)bean.create();  
//        String result = helloWorldService.say("Brofe");  
//        System.out.println(result); 
		
		/**
		 * 通过WSDL调用
		 */
		JaxWsDynamicClientFactory clientFactory = JaxWsDynamicClientFactory.newInstance();
        Client client = clientFactory.createClient("http://localhost:8088/training/ws/helloWorldService?wsdl");
        client.getInInterceptors().add(new LoggingInInterceptor());
        client.getOutInterceptors().add(new LoggingOutInterceptor());
        Object[] result;
		try {
			result = client.invoke("say", "brofe");
			 System.out.println(result[0]); 
		} catch (Exception e) {
			e.printStackTrace();
		}  
	}
}
