以前工作中也用CXF,但都是用別人現成搭好的環境，這次自己重頭搭建一遍環境。過程中也有遇到的問題，也做了簡單的整理。

對于CXF是干什么用的，我不想多說，大家都知道這是我們在java編程中webService技術的一種實現工具。我們說說為什么用CXF來實現webService：

1.??????Java的webService實現本身就是一個很耗性能的實現方案（xml與java對象之間在服務端以及客戶端的互轉比較消耗性能）

2.??????目前java主流的webService應用以CXF、AXIS2為主；

3.??????通過網絡渠道的了解,目前CXF的效率要比AXIS2高出至少50%；

4.??????另外有一個webService的工具metro的效率比CXF高出10%；

5.??????CXF的實現資料網上可以隨便找出一大堆，metro的資料相對少一些；

6.??????CXF在java應用實現中已經很成熟，企業更傾向于用這樣一個成熟的解決方案；

基于以上原因，我選擇CXF來實現webService。

一 ? 以annotation注解方式實現發布webService應用

1、? 基礎環境

新建java web工程cxf之后，下載cxf工具包。解壓CXF之后，把cxf工具包lib下的jar包全部放到工程的lib下。

此處用到的cxf工具包版本為：apache-cxf-2.7.12

下載地址：

http://www.apache.org/dyn/closer.cgi?path=/cxf/2.7.12/apache-cxf-2.7.12.zip

?

2、? 編寫服務接口

見文件HelloWorld.java

[java]?view plain?copy ?

package?com.hsy.server;??

??

import?java.util.List;??

??

import?javax.jws.WebParam;??

import?javax.jws.WebService;??

??

import?com.hsy.pojo.User;??

??

@WebService??

public?interface?HelloWorld?{??

????String?sayHi(@WebParam(name="text")String?text);??

????String?sayHiToUser(User?user);??

????String[]?SayHiToUserList(List<User>?userList);??

}??

?

3、? 服務接口實現

見文件HelloWorldImpl.java

[java]?view plain?copy ?

package?com.hsy.server;??

??

import?java.util.LinkedHashMap;??

import?java.util.List;??

import?java.util.Map;??

??

import?javax.jws.WebParam;??

import?javax.jws.WebService;??

??

import?com.hsy.pojo.User;??

??

@WebService(endpointInterface="com.hsy.server.HelloWorld",serviceName="HelloWorld")??

public?class?HelloWorldImpl?implements?HelloWorld?{??

????Map<Integer,?User>?users?=?new?LinkedHashMap<Integer,?User>();??

??

????public?String?sayHi(@WebParam(name?=?"text")?String?text)?{??

????????return?"Hello,"+text;??

????}??

??

????public?String?sayHiToUser(User?user)?{??

????????users.put(users.size()+1,?user);??

????????return?"Hello,"+user.getName();??

????}??

??

????public?String[]?SayHiToUserList(List<User>?userList)?{??

????????String[]?result?=?new?String[userList.size()];??

????????int?i?=?0;??

????????for(User?u:userList){??

????????????result[i]?=?"Hello?"?+?u.getName();??

????????????i++;??

????????}??

????????return?result;??

????}??

??

????/**?

?????*?@param?args?

?????*/??

????public?static?void?main(String[]?args)?{??

????????//?TODO?Auto-generated?method?stub??

??

????}??

??

}??

4、? 發布服務app

見文件webServiceApp.java

[java]?view plain?copy ?

package?com.hsy.server;??

??

import?javax.xml.ws.Endpoint;??

??

public?class?webServiceApp?{??

??

????/**?

?????*?@param?args?

?????*/??

????public?static?void?main(String[]?args)?{??

?????????System.out.println("web?service?start");??

?????????HelloWorldImpl?implementor?=?new?HelloWorldImpl();??

?????????String?address?=?"http://localhost:8080/helloWorld";??

?????????Endpoint.publish(address,?implementor);??

?????????System.out.println("web?service?started");??

????}??

??

}??

右鍵 run as 選擇java application發布服務；然后在瀏覽器輸入地址：http://localhost:8080/helloWorld?wsdl

如圖：20140805132120.jpg

說明webService服務發布成功。

?

5、? 客戶端訪問服務

見文件HelloWorldClient.java

[java]?view plain?copy ?

package?com.hsy.client;??

??

import?org.apache.cxf.jaxws.JaxWsProxyFactoryBean;??

??

import?com.hsy.pojo.User;??

import?com.hsy.server.HelloWorld;??

??

public?class?HelloWorldClient?{??

??

????/**?

?????*?@param?args?

?????*/??

????public?static?void?main(String[]?args)?{??

??????????

????????//首先右鍵run?as?運行com.hsy.server.webServiceApp類，然后再運行這段客戶端代碼??

????????JaxWsProxyFactoryBean?jwpfb?=?new?JaxWsProxyFactoryBean();??

????????jwpfb.setServiceClass(HelloWorld.class);??

????????jwpfb.setAddress("http://localhost:8080/helloWorld");??

????????HelloWorld?hw?=?(HelloWorld)?jwpfb.create();??

????????User?user?=?new?User();??

????????user.setName("馬克思");??

????????user.setDescription("懷念馬克思");??

????????System.out.println(hw.sayHiToUser(user));??

??????????

????}??

??

}??

右鍵 run as 選擇java application，控制臺打印如圖：

20140805132610.jpg

Ok，客戶端訪問也成功了。

6、? 附：

User.java

[java]?view plain?copy ?

package?com.hsy.pojo;??

??

import?java.io.Serializable;??

??

@SuppressWarnings("serial")??

public?class?User?implements?Serializable?{??

??

????private?String?id;??

????private?String?name;??

????private?String?age;??

????private?String?description;??

??????

????public?User()?{??

????????super();??

????}??

??

????public?String?getId()?{??

????????return?id;??

????}??

??

????public?void?setId(String?id)?{??

????????this.id?=?id;??

????}??

??

????public?String?getName()?{??

????????return?name;??

????}??

??

????public?void?setName(String?name)?{??

????????this.name?=?name;??

????}??

??

????public?String?getAge()?{??

????????return?age;??

????}??

??

????public?void?setAge(String?age)?{??

????????this.age?=?age;??

????}??

??

????public?String?getDescription()?{??

????????return?description;??

????}??

??

????public?void?setDescription(String?description)?{??

????????this.description?=?description;??

????}??

??????

??????

}??

?

二與spring集成實現webService

1、? 配置web.xml

見文件web.xml

[html]?view plain?copy ?

<?xml?version="1.0"?encoding="UTF-8"?>??

<web-app?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"?xmlns="http://java.sun.com/xml/ns/javaee"?xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"?xsi:schemaLocation="http://java.sun.com/xml/ns/javaee?http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"?id="WebApp_ID"?version="2.5">??

????????<filter-name>encoding</filter-name>????

????????<url-pattern>*.3g</url-pattern>????

????</filter-mapping>?????

????

</web-app>??

?

2、? 配置applicationContext.xml

見文件applicationContext.xml

[html]?view plain?copy ?

<?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:jaxws="http://cxf.apache.org/jaxws"??

???????xsi:schemaLocation="??

?????????????http://www.springframework.org/schema/beans??

?????????????http://www.springframework.org/schema/beans/spring-beans.xsd??

?????????????http://cxf.apache.org/jaxws???

?????????????http://cxf.apache.org/schemas/jaxws.xsd">??

??

??????<import?resource="classpath:META-INF/cxf/cxf.xml"/>??

??????<import?resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>??

??????<import?resource="classpath:META-INF/cxf/cxf-servlet.xml"/>??

??

??????<jaxws:endpoint???

?????????????id="helloWorld"??

?????????????implementor="com.hsy.server.HelloWorldImpl"??

?????????????address="/helloWorld"?/>??

??

?????<bean?id="client"???

????????????class="com.hsy.server.HelloWorld"???

????????????factory-bean="clientFactory"???

????????????factory-method="create"/>??

??

?????<bean?id="clientFactory"?class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">??

????????????<property?name="serviceClass"?value="com.hsy.server.HelloWorld"/>??

????????????<property?name="address"?value="http://localhost:8080/cxf/webservice/helloWorld"/>??

?????</bean>??

???????

</beans>??

?

3、? 修改客戶端代碼

見文件HelloWorldClient.java

[java]?view plain?copy ?

package?com.hsy.client;??

??

import?java.util.ArrayList;??

import?java.util.List;??

??

import?org.springframework.beans.factory.BeanFactory;??

import?org.springframework.beans.factory.xml.XmlBeanFactory;??

import?org.springframework.context.ApplicationContext;??

import?org.springframework.context.support.ClassPathXmlApplicationContext;??

import?org.springframework.core.io.FileSystemResource;??

import?org.springframework.core.io.Resource;??

??

import?com.hsy.pojo.User;??

import?com.hsy.server.HelloWorld;??

??

public?class?HelloWorldClient?{??

??

????/**?

?????*?@param?args?

?????*/??

????public?static?void?main(String[]?args)?{??

??????????

????????//Resource?resource=?new?FileSystemResource("F:/workspaces4me2013/.metadata/.me_tcat/WEB-INF/classes/applicationContext.xml");?????

????????//BeanFactory?factory=?new?XmlBeanFactory(resource?);???

????????ApplicationContext?factory?=?new?ClassPathXmlApplicationContext("/applicationContext.xml");??

????????HelloWorld?client?=?(HelloWorld)factory.getBean("client");??

????????User?user1?=?new?User();??

????????user1.setName("馬克思");??

????????user1.setDescription("懷念馬克思");??

????????User?user2?=?new?User();??

????????user2.setName("恩格斯");??

????????user2.setDescription("懷念恩格斯");??

????????List<User>?userList=?new?ArrayList<User>();??

????????userList.add(user1);??

????????userList.add(user2);??

????????String[]?res?=?client.SayHiToUserList(userList);??

????????System.out.println(res[0]);??

????????System.out.println(res[1]);????

??????????

????}??

??

}??

?

4、? 啟動tamcat發布webService

然后在瀏覽器輸入地址：http://localhost:8080/cxf/webservice/helloWorld?wsdl

如圖：20140805133642.jpg

說明webService服務發布成功。

?

5、? 運行客戶端代碼訪問webService

右鍵 run as 選擇java application，控制臺打印如圖：

20140805134838.jpg

Ok，客戶端訪問也成功了。
