多系统（异构系统）进行交互时，一种良好的方式便是调用Web Service，本示例基于Apache组织的CXF，为了方便起见特将服务端和客户端写在同一个工程下，实际项目中是不可能的，但是客户端却依赖于服务 端的Web Service接口，那么可以通过导出jar的方式。

环境：
MyEclipse10
JDK6
Tomcat7
CXF2.5
Spring3

示例项目结构图：

文档结构图

如上图所示，全部依赖的第三方库都在lib中，下面贴出全部代码。
IHelloService.java

package bing.server;import javax.jws.WebService;/*** <p>* WebService接口* </p>** @author IceWee* @date 2012-7-6* @version 1.0*/@WebServicepublic interface IHelloService {    public String sayHello(String username);   }


HelloServiceImpl.java

package bing.server;import javax.jws.WebService;/*** <p>* WebService实现类* </p>** @author IceWee* @date 2012-7-6* @version 1.0*/@WebService(endpointInterface = "bing.server.IHelloService", serviceName = "HelloService")public class HelloServiceImpl implements IHelloService {    @Override    public String sayHello(String username) {        return "hello, " + username;    }}

HelloServiceClient.java

package bing.client;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import bing.server.IHelloService;/*** <p>* WebService调用方-客户端* </p>** @author IceWee* @date 2012-7-6* @version 1.0*/public class HelloServiceClient {    public static void main(String[] args) {        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");        IHelloService helloService = (IHelloService) context.getBean("client");        String response = helloService.sayHello("Peter");        System.out.println(response);    }}

所有项目都已配置完成，可以发布到Tomcat了，在浏览器中输入：http://localhost:8080/CXFDemo/ws，返回如图：

从上图中可以看到我们对外发布的WebService接口，点击蓝色超链接，返回如图：

到此，证明我们的Web Service已经发布成功，可以进行调用测试了。运行HelloServiceClient，返回如图：

补充：

1.启动时报错，class not fount

解决：需要加载spring的jar包和cxf的jar包。网上均有资源可以下载引用。

2.测试client端报错

java.lang.LinkageError: 正在从引导类加载器加载 JAXB 2.1 API, 但此 RI (来自jar:file:/D:/Program%20Files/JAVA_JDK_45/lib/endorsed/jaxb-impl- 2.2.6.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) 需要 2.2 API。请使用授权目录机制将 jaxb-api.jar 放在引导类加载器中。(请参阅 http://java.sun.com/j2se/1.6.0/docs/guide/standards/)

解决：需要把jre System Library 放在第一位。
