spring3 mvc的拦截器

Question

@Authority(controllerName = "admin", pri= "save")
@RequestMapping(value = "/save")
public String save(Model model) {
}public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {

return true;
}我想通过拦截器直接取到请求controller的Method从而取得权限注解@Authority做方法权限处理··请问应该怎么做呢·
按网上说这样试过:ServletHandlerMethodResolver methodResolver = getMethodResolver(handler);
Method handlerMethod = methodResolver.resolveHandlerMethod(request);但没用``
请问下这里应该怎么做呢··谢谢大家

 @Override
    public void doFilter(ServletRequest requestSer, ServletResponse responseSer, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) requestSer;
        HttpServletResponse response = (HttpServletResponse) responseSer;
      
        // 设置请求参数
        setParameters(WebUtils.getParametersStartingWith(request, ""));
        // 获取根目录所对应的绝对路径:
        String currentURI = request.getRequestURI();
        log.info("doFilter.currentURI: " + currentURI);
        log.info("request.getContextPath():"+ request.getContextPath()+".");
        // 截取命名空间、action、路径参数
        String targerURI ="";
        if ("".equals(request.getContextPath())) {
            targerURI = currentURI.substring(currentURI.indexOf("/", 0), currentURI.length());
        }else{
            targerURI = currentURI.substring(currentURI.indexOf("/", 1), currentURI.length());
        }
        log.info("doFilter.targerURI: " + targerURI);
        
        if ("/".equals(targerURI)|| (!targerURI.endsWith(".htm"))) {
            chain.doFilter(request, response);
            return;
       }
        
        // 如果属于白名单，直接返回
        if (checkBlank(targerURI)) {
             chain.doFilter(request, response);
             return;
        }        HttpSession session = request.getSession();        // 子系统登录
        if (null == session || session.getAttribute(SessionConstants.SESSION_USER) == null) {
            request.getSession().setAttribute(SessionConstants.SESSION_PRE_URL, request.getRequestURL());
            response.sendRedirect(request.getContextPath() + VGS_LOGIN_URL);
            return;
        }
        
        // 从COOKIE中取出B2C登陆信息
        Cookie[] cookies = request.getCookies();
        String memberId = "";
        if (null != cookies) {
            for (Cookie cookie : cookies) {
                if (cookie.getName().startsWith("WC_USERACTIVITY_")) {
                    memberId = cookie.getName().substring(cookie.getName().lastIndexOf("_") + 1); // 取出B2C登陆的会员ID
                    //log.info("doFilter.memberId: "+memberId); 
                    break;
                }
            }
        }
