参考:CXF Spring整合 ——又一个helloword！ http://pphqq.iteye.com/blog/1447800
使用apache CXF和maven开发Web Service http://www.cnblogs.com/holbrook/archive/2012/12/12/2814821.html
Web Service的CXF实现(Spring整合方式) http://m.oschina.net/blog/196308
一个依赖问题:
tomcat下运行cxf异常 java.lang.ClassCastException http://m.blog.csdn.net/blog/xyzroundo/9086205
A: 如果希望以一种一致的方式实现webservice，特别是有跨语言的需求时，应该使用Axis2
B: 如果需要在现有的java程序（包括web应用）中增加webservice支持，应该使用CXF

注解：
标注 说明
WebService 将 Java 类标记为实现 Web Service，或者将 Java 接口标记为定义 Web Service 接口
WebMethod 定制Web Service方法
WebParam 定制Web Service方法的参数
WebResult 定制Web Service方法的返回值
SOAPBinding 指定WebService的SOAP映射样式

User.java 
package com.module;

import java.io.Serializable;

/**
 * Created by Administrator on 14-5-21.
 */
public class User implements Serializable {


    private static final long serialVersionUID = 2035807023987192387L;
    private String userName;
    private String userCode;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserCode() {
        return userCode;
    }

    public void setUserCode(String userCode) {
        this.userCode = userCode;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof User)) return false;

        User user = (User) o;

        if (userCode != null ? !userCode.equals(user.userCode) : user.userCode != null) return false;
        if (userName != null ? !userName.equals(user.userName) : user.userName != null) return false;

        return true;
    }

    @Override
    public int hashCode() {
        int result = userName != null ? userName.hashCode() : 0;
        result = 31 * result + (userCode != null ? userCode.hashCode() : 0);
        return result;
    }


    @Override
    public String toString() {
        return "User{" +
                "userName='" + userName + '\'' +
                ", userCode='" + userCode + '\'' +
                '}';
    }
}




下面开始写服务器端代码，首先定制服务器端的接口，代码如下：
IHelloWorld.java 
package com.service;

import javax.jws.WebService;

/**
 * Created by Administrator on 14-5-21.
 * 定制服务器端的接口
 */
@WebService
public interface IHelloWorld {
    public String sayHello(String name);

    public User getUser(String name);
}




下面编写WebService的实现类，服务器端实现代码如下：
注意的是和Spring集成，这里一定要完成接口实现，如果没有接口的话会有错误的。
HelloWorldImpl.java 
package com.service.impl;

import com.service.IHelloWorld;

/**
 * Created by Administrator on 14-5-21.
 * WebService的实现类，服务器端实现代码
 * 注意的是和Spring集成，这里一定要完成接口实现，如果没有接口的话会有错误的。
 */
public class HelloWorldImpl implements IHelloWorld {


    public String sayHello(String name) {
        System.out.println("sayHello is called by " + name);
        return "服务器返回的信息[" + name+"]";
    }


    @Override
    public User getUser(String name) {
        User user = new User();
        user.setUserCode("Pandy");
        user.setUserName(name);
        return user;
    }
}





下面要在applicationContext-server.xml文件中添加如下配置： applicationContext-client.xml 
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.0.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"/>

    <!--
        定义一个客户端的类，用来连接WebService的信息
             这个和服务端开放的借口是实现同一个类的。
    -->
    <jaxws:client id="helloWorldClient" address="http://localhost:8080/SpringCXF/ws/HelloWorld" serviceClass="com.service.IHelloWorld"/>
</beans>

下面启动tomcat服务器后，在WebBrowser中请求：
http://localhost:8080/SpringCXF/ws/HelloWorld?wsdl
---------------------- 
<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions name="HelloWorldImplService" targetNamespace="http://impl.service.com/" xmlns:ns1="http://service.com/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <wsdl:import location="http://localhost:8080/SpringCXF/ws/HelloWorld?wsdl=IHelloWorld.wsdl" namespace="http://service.com/">
    </wsdl:import>
  <wsdl:binding name="HelloWorldImplServiceSoapBinding" type="ns1:IHelloWorld">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="getUser">
      <soap:operation soapAction="" style="document"/>
      <wsdl:input name="getUser">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="getUserResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
    <wsdl:operation name="sayHello">
      <soap:operation soapAction="" style="document"/>
      <wsdl:input name="sayHello">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="sayHelloResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="HelloWorldImplService">
    <wsdl:port binding="tns:HelloWorldImplServiceSoapBinding" name="HelloWorldImplPort">
      <soap:address location="http://localhost:8080/SpringCXF/ws/HelloWorld"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

如果你能看到wsdl的xml文件的内容，就说明你成功了，注意的是上面地址的HelloWorld就是上面xml配置中的address的名称，是一一对应的。



下面编写客户端请求的代码，代码如下：
Client.java 
package com.client;

/**
 * Created by Administrator on 14-5-21.
 * 客户端调用服务端，许多东西都被Spring和CXF自己处理了，只实现调用和输出就好。
 *
 */
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.service.IHelloWorld;

public class Client {

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
        IHelloWorld helloWorld = (IHelloWorld) context.getBean("helloWorldClient");
        System.out.println(helloWorld.sayHello("客户端传进去的信息"));
        System.out.println(helloWorld.getUser("Panyongzheng").toString());
    }

}





先运行服务器
在以应用程序的方式运行客户端，得到输出：
......
org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://service.com/}IHelloWorldService from class com.service.IHelloWorld
服务器返回的信息[客户端传进去的信息]
