以前工作中也用CXF,但都是用别人现成搭好的环境，这次自己重头搭建一遍环境。过程中也有遇到的问题，也做了简单的整理。

对于CXF是干什么用的，我不想多说，大家都知道这是我们在java编程中webService技术的一种实现工具。我们说说为什么用CXF来实现webService：

1.??????Java的webService实现本身就是一个很耗性能的实现方案（xml与java对象之间在服务端以及客户端的互转比较消耗性能）

2.??????目前java主流的webService应用以CXF、AXIS2为主；

3.??????通过网络渠道的了解,目前CXF的效率要比AXIS2高出至少50%；

4.??????另外有一个webService的工具metro的效率比CXF高出10%；

5.??????CXF的实现资料网上可以随便找出一大堆，metro的资料相对少一些；

6.??????CXF在java应用实现中已经很成熟，企业更倾向于用这样一个成熟的解决方案；

基于以上原因，我选择CXF来实现webService。

一 ? 以annotation注解方式实现发布webService应用

1、? 基础环境

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

此处用到的cxf工具包版本为：apache-cxf-2.7.12

下载地址：

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

2、? 编写服务接口

见文件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、? 服务接口实现

见文件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、? 发布服务app

见文件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");??
????}??
??
}??

右键 run as 选择java application发布服务；然后在浏览器输入地址：http://localhost:8080/helloWorld?wsdl

如图：20140805132120.jpg

说明webService服务发布成功。

5、? 客户端访问服务

见文件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)?{??
??????????
????????//首先右键run?as?运行com.hsy.server.webServiceApp类，然后再运行这段客户端代码??
????????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("马克思");??
????????user.setDescription("怀念马克思");??
????????System.out.println(hw.sayHiToUser(user));??
??????????
????}??
??
}??

右键 run as 选择java application，控制台打印如图：

Ok，客户端访问也成功了。

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;??
????}??
??????
??????
}??

二与spring集成实现webService

1、? 配置web.xml

见文件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-mapping>????
????????<filter-name>encoding</filter-name>????
????????<url-pattern>*.3g</url-pattern>????
????</filter-mapping>?????
????
</web-app>??

2、? 配置applicationContext.xml

见文件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、? 修改客户端代码

见文件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("马克思");??
????????user1.setDescription("怀念马克思");??
????????User?user2?=?new?User();??
????????user2.setName("恩格斯");??
????????user2.setDescription("怀念恩格斯");??
????????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、? 启动tamcat发布webService

然后在浏览器输入地址：http://localhost:8080/cxf/webservice/helloWorld?wsdl

如图：20140805133642.jpg

说明webService服务发布成功。

5、? 运行客户端代码访问webService

右键 run as 选择java application，控制台打印如图：

20140805134838.jpg

Ok，客户端访问也成功了。

?此篇实现了webService服务的发布以及在本工程下的客户端调用服务的示例，或许不是很直观。

请看下一篇：CXF客户端代码生成与服务调用（二）
