dubbo REST添加扩展的filter时，如何注入Spring中的Bean ?

[sunxboy]

<dubbo:protocol name="rest" port="${dubbo.protocol.rest.port}" threads="500" contextpath="rest" server="tomcat" accepts="500" extension="com.pip.rest.serv.extension.AuthenticationTraceFilter"/>

如上配置，添加了一个扩展，AuthenticationTraceFilter 分别实现了ContainerRequestFilter，ContainerResponseFilter接口。 我想在AuthenticationTraceFilter引入spring中的其它对象，怎么做？@Autowired注解试过了，不行。

@Priority(900)
@PreMatching
@Provider
public class AuthenticationTraceFilter implements ContainerRequestFilter, ContainerResponseFilter {

    @Context
    private HttpServletRequest httpRequest;
    @Autowired
    private MyService service;
 ...........
}

static { userService = BeanContext.getBean(UserService.class); applicationDao = BeanContext.getBean(ApplicationDao.class); } public class BeanContext implements ApplicationContextAware
