对于handler不需要实现任何接口

@Controllerpublic class ItemsHandler3 {        @RequestMapping("/queryitems")    public ModelAndView queryitems(){        //*****************        ModelAndView modelAndView = new ModelAndView();        modelAndView.addObject(itemsList);        modelAndView.setViewName("/WEB-INF/jsp/items/itemsList.jsp");        return modelAndView;    }

访问路径为/queryitems.action
