java axis调用cxf 的坑object is not an instance of declaring class while invoking public

简单说一下出错的场景，项目需要为别人系统开放webservice,于是在springmvc框架下集成cxf开发webservice接口，网上教程一大堆，小有波折，参考的
https://my.oschina.net/long0419/blog/192788，我用的maven工程，cxf依赖如下：
<dependency>  

        <groupId>org.apache.cxf</groupId>  

        <artifactId>cxf-rt-frontend-jaxws</artifactId>  

        <version>${cxf.version}</version>  

 </dependency>  

<dependency>  

        <groupId>org.apache.cxf</groupId>  

        <artifactId>cxf-rt-frontend-jaxws</artifactId>  

        <version>${cxf.version}</version>  

 </dependency>  

 <dependency>  
       <groupId>org.apache.cxf</groupId>  
       <artifactId>cxf-rt-transports-http</artifactId>  
       <version>${cxf.version}</version>  

</dependency>  
       <!-- Jetty is needed if you're are not using the CXFServlet -->  

<dependency>  
       <groupId>org.apache.cxf</groupId>  
       <artifactId>cxf-rt-transports-http-jetty</artifactId>  
       <version>${cxf.version}</version>  

</dependency> 

<properties>下加入版本

<cxf.version>2.2.3</cxf.version> ,

web.xml下配置classpath:webservice/webservice.xml,配置servlet,这个按照https://my.oschina.net/long0419/blog/192788的介绍，完全没问题，

值得注意的是，在webservice.xml中

<beans

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"

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

    <!-- 接口的实现类声明 -->
    <jaxws:endpoint id="testservice" 

        implementorClass="com.fy.util.webservice.TestWebServiceImpl" 

        address="/testws" />

</beans>

<jaxws:endpoint id="testservice" 

        implementorClass="com.fy.util.webservice.TestWebServiceImpl" 

        address="/testws" />这里我这样定义的接口实现位置，完成接口，项目发布后，没有错误，打开浏览器，输入http://localhost:8880/fs_door/ws/testws?wsdl，页面显示如下：

到此，我以为webservice服务的开发已经ok了，但自己用写客户端测试，用的axis，jar包网上很容易找到，如需要请留言，测试代码如下：

Service service = new Service();
Call call;
String result="";

try {
call = (Call)service.createCall();
call.setTargetEndpointAddress("http://localhost:8880/fs_door/ws/testws");// 远程调用路径
call.setOperationName(new QName("http://webservice.util.fy.com/", "test"));

call.addParameter("name", // 参数名
XMLType.XSD_STRING,// 参数类型:String
ParameterMode.IN);
call.setReturnType(XMLType.XSD_STRING);
call.setUseSOAPAction(true);
result=(String) call.invoke(new Object[]{"asdf"});

} catch (ServiceException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
} 
catch (Exception e) {
System.out.println(e.getMessage());
}
System.out.println(result);

测试别的webservice接口都ok，可是测试上面的接口时，一直报错：

反复的检查客户端调用程序无果，最后怀疑服务端有问题，才回到服务端有关于webservice的所有地方。

问题原因：<jaxws:endpoint id="testservice" 
        implementorClass="com.fy.util.webservice.TestWebServiceImpl" address="/testws"
/>

这一句换成

<bean id="hello" class="com.fy.util.webservice.TestWebServiceImpl"
/>

<jaxws:endpoint id="testws" implementor="#hello" address="/testws"
/>

问题解决，至于为什么，尚在学习，希望知道的大神能指点留言，非常感谢！
