Java Spring portlet ajax调用fmt不显示消息

我在ajax控制器中使用以下代码来加载html并使用jquery返回，问题是html输出并没有显示fmt:消息，而是？？当我尝试不使用ajax调用时，这个JSP工作得很好。谢谢你的帮助

 @Controller("ajaxRequestController")
    @RequestMapping(value = "VIEW")
    public class AjaxRequestController implements PortletConfigAware  {

        @ResourceMapping("entitledRequest")
            public void getServiceAutoComplete(@RequestParam("accNum")  String accNum, ResourceRequest request, ResourceResponse response){
            portletConfig.getPortletContext().getRequestDispatcher("/WEB-INF/jsp/account_summary.jsp").include(request, response);
        }

@Override
    public void setPortletConfig(PortletConfig portletConfig) {
    this.portletConfig = portletConfig;
    }

}

但问题是，由于代码中的下一行，Spring并没有正确处理您的视图

 portletConfig.getPortletContext().getRequestDispatcher("/WEB-INF/jsp/account_summary.jsp").include(request, response);

尝试将其更改为下面提到的代码。我想您已经在Spring上下文文件中定义了viewResolver

  @ResourceMapping("entitledRequest")
        public String getServiceAutoComplete(@RequestParam("accNum")  String accNum, ResourceRequest request, ResourceResponse response){
        //portletConfig.getPortletContext().getRequestDispatcher("/WEB-INF/jsp/account_summary.jsp").include(request, response);
        return "account_summary";
    }
