Tomee与spring管理的cxf jaxrs休息服务无法正常工作

我有一个使用JAX-RS注释和spring CDI的应用程序。 它在tomcat（apache-tomcat-7.0.57）中工作正常，但在Tomee-plus（apache-tomee-plus-1.7.2）中它不会运行错误：

  

命名空间[http://cxf.apache.org/jaxrs]

的NamespaceHandler类[org.apache.cxf.jaxrs.spring.NamespaceHandler]无效

在tomcat版本中，我在.war文件中包含了cxf-rt-frontend-jaxrs和cxf-rt-transports-http jars，而对于Tomee-plus版本，我将这些jar标记为提供，如tomee-plus已经有了。

这是我的pom（只是因为所有存在的依赖关系（这是提供scope =的tomee-plus版本）：

    <cxf.version>2.6.16</cxf.version>

这是我的春季配置

            <ref bean="userService" />
        </jaxrs:serviceBeans>
    </jaxrs:server>
</beans>

这是web.xml 

<web-app>

      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicationConfig.xml</param-value>

    <servlet-mapping>
        <servlet-name>cxf</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>
</web-app>

这是我的REST服务

@Component
@Path("/user")
public  class UserService {
    @GET
    @Path("get")
    public String get(){
        return "hello";
    }

}

在tomcat中运行时一切正常，但是在tomee-plus中我得到以下异常（请注意，在tomee-plus中，cxf jar在tomee lib目录中提供，因此不包含在.war文件中）< / p>

根本原因报告为org.springframework.beans.factory.xml.NamespaceHandlerSupport未找到的类，但我认为这是误导性的。 在跟踪代码时，我发现错误是由于'org.apache.cxf.jaxrs.spring.NamespaceHandler'因为LinkageError而无法加载而引起的。

我需要这个的原因是因为我正在尝试将使用cfx和spring的第三方库集成到现有应用程序中。

这个错误是否与tomee-plus中的类加载问题有关，因为cxf在tomee lib中？

如果我将弹簧罐移动到tomee-plus lib目录中，它可以正常工作，但是，我们要避免必须修改tomee。

有没有人知道如何解决这个问题，以便spring / cfx应用可以在tomee-plus中运行？
