通过@Resource 注解的WebServiceContext 注入问题

Question

我在通过 @Resource 注释注入 WebServiceContext 时遇到问题。 我正在使用 JAXWS + Spring 组合。 这是我使用的一段代码。

@WebService 
public class AdminWSImpl {

  @Resource
  private WebServiceContext context;

...
}

我的 web.xml 的一部分：

...
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


<listener>
    <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
</listener>


<servlet>
    <description>JAX-WS endpoint of Admin Service</description>
    <display-name>JAX-WS Admin servlet</display-name>
    <servlet-name>AdminService</servlet-name>
    <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>


<servlet>
    <servlet-name>context</servlet-name>
    <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>     
    <load-on-startup>2</load-on-startup>
</servlet>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

问题是上下文总是空的！ 根据How to use @Resource WebServiceContext injection with Spring's @Transactionalsprings-transactional，我已经为上下文定义了setter，并将@Resource注解放在了setter上。

将@Resource 注解放在setter 上的结果是这个堆栈跟踪：

    javax.xml.ws.WebServiceContext is an interface, and JAXB can't handle interfaces.

谁能提供帮助？

提前谢谢你！

我找到了现在可行的解决方案！ 我将 WebService 注释与 endpointInterface 属性一起添加，并添加了由 wsimport 生成的类实现 Admin 接口。 我的 web.xml 与问题中描述的保持一致！

  @WebService(endpointInterface = "my.app.admin.Admin")
  public class AdminWSImpl implements Admin{

  @Resource
  private WebServiceContext wsContext;

  public void setWsContext(WebServiceContext wsContext) {
    this.wsContext = wsContext;
}
 }
