### 一、CXF的介绍 ###

Apache CXF是一个开源的WebService框架，CXF大大简化了Webservice的创建，同时它继承了XFire的传统，一样可以和[spring][]天然的进行无缝的集成。CXF框架是一种基于servlet技术的SOA应用开发框架，要正常运用基于CXF应用框架开发的企业应用，除了CXF应用本身之外，还需要JDK和servlet容器的支持。

## 三、创建webservice服务端 ##

### 1在web.xml中添加cxf的核心servlet ###

<servlet>
    		<servlet-name>CXFServlet</servlet-name>
    		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    		<load-on-startup>1</load-on-startup>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>CXFServlet</servlet-name>
    		<url-pattern>/webservice/*</url-pattern>
    	</servlet-mapping>

### 2在applicationContext.xml中配置webservice服务 ###

### 3 定义webservice接口和实现类。 ###

@WebService
    public interface GetInfo {
    	
    	/*发现有时不用@WebParam也可以接收到参数*/
    	public void sayHello(@WebParam(name="userName") String userName,@WebParam(name="age") int age);	
    }

@WebService(targetNamespace="http://inter.webservice.zhan.com/",
    endpointInterface="com.zhan.webservice.inter.GetInfo")
    public class GetInfoImpl implements GetInfo {
    
    	public GetInfoImpl() {
    		System.out.println("service GetInfoImpl()..");
    	}
    
    	@Override
    	public String sayHello(String name,int age) {
      		System.out.println("service sayHello()..."+ name +",年龄："+age);
     		return "hello:"+name +"年龄："+age;
     	}
    }

###        4 保存代码，启动tomcat，发布项目。 ###

地址栏输入：[http://localhost:8080/webservice\_cxf\_server/webservice/getInfo?wsdl 即可看到文档][http_localhost_8080_webservice_cxf_server_webservice_getInfo_wsdl]

## 四、创建webservice客户端 ##

### 1、新建java工程：webservice\_cxf\_client测试代码如下： ###

import java.net.URL;
    import javax.xml.namespace.QName;
    import org.apache.axis.client.Call;
    import org.apache.axis.client.Service;
    import org.apache.cxf.endpoint.Client;
    import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
    
    public class ClientTest {
    
    	public static void main(String[] args) {
    		JaxWsDynamicClientFactory cf = JaxWsDynamicClientFactory.newInstance();
    		String wsurl = "http://127.0.0.1:8080//webservice_cxf_server/webservice/getInfo?wsdl";
    		Client client = cf.createClient(wsurl);
    		String namespace = "http://inter.webservice.zhan.com/";
    		String method="sayHello";
    		 try {
    			/**
    			 * cxf方式 : 2种方式
    			 */
    			 //第1种方式：不使用命名空间，直接使用方法名
    			Object[] objects=client.invoke(method,"cxf1",11);//方法名,参数
    			System.out.println("=="+objects[0].toString());
    			
    			//第2种方式：使用命名空间，使用QName对象(QName+方法名)+参数，
    			QName qname = new QName("http://inter.webservice.zhan.com/", method);//(namespace,method)
    			Object[] objects2=client.invoke(qname,"cxf2",22);//QName,参数
    			System.out.println(objects2[0]); 
    			
    			/**
    			 * axis 调用webservice
    			 */
    			Service service = new Service();
    			Call call = (Call) service.createCall();
    			call.setTargetEndpointAddress(wsurl);//wsurl换为new URL(wsurl)也可以
    			call.setOperation(method);// 要调用的方法名
    			call.setUseSOAPAction(true);
    			call.setOperationName(new QName(namespace,method));
    			call.addParameter(
    					"userName",//如果服务端收不到参数，可以试试 new QName(namespace,"userName"), 
    					org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
    			call.addParameter("age",//如果服务端收不到参数，可以试试 new QName(namespace,"age"), 
    					org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
    			call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
    			String str = (String) call.invoke(new Object[]{"axis",33});
    			System.out.println(str);
    			
    		} catch (Exception e) {
    			e.printStackTrace();
    		}   
    		 
    	}
    
    }

二、xfire开发webservice

1.web.xml 配置：xfire

<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>
    			classpath:applicationContext.xml,
    		        classpath:xfire-servlet.xml
    		</param-value>
    	</context-param>

<servlet>
    		<servlet-name>XFireServlet</servlet-name>
    		<servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>XFireServlet</servlet-name>
    		<url-pattern>/services/*</url-pattern>
    	</servlet-mapping>

2.配置xfire-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    	xmlns:tx="http://www.springframework.org/schema/tx"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
                http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
    	
    	
    	
    	<bean name="lsService" class="org.codehaus.xfire.spring.ServiceBean">
    		<property name="serviceBean" ref="lservice" />
    		<property name="serviceClass" value="com.myland.webservice.service.LearnerService" />
    		<property name="inHandlers">
    			<list>
    				<ref bean="addressingHandler"/>
    			</list>
    		</property>
    	</bean>

3.编写接口和实现类：

/\*\*  
 \* 删除学员信息  
 \* @author gyz  
 \* 2017年11月3日 上午11:28:12  
 \*  
 \*/  
public interface LearnerService \{  
   
  public String deleteLearner(String icCard,String area);  
    
\}

public class LearnerServiceImpl   implements LearnerService \{  
   
 private static final Logger log = Logger.getLogger(LearnerServiceImpl.class);  
   
 @SuppressWarnings("unchecked")  
 public String deleteLearner(String icCard, String area) \{

//TODO 。。。

｝

4.http://127.0.0.1/gx/services/LearnerService?wsdl.....打开。

5.客户端采用cxf调用：

public static void main(String\[\] args) throws Exception \{  
    
  JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();  
   Client client = dcf.createClient("http://127.0.0.1/gx/services/LearnerService?wsdl");  
   Object\[\] objects = client.invoke("deleteLearner", new Object\[\]\{"24354","450800"\});  
   System.out.println("Echo response: "+ objects\[0\]);

｝
