@Fail("jsp:jsp/login")
@Ok("jsp:jsp/index")
@At
@RequiresRoles("admin")
public Result downloadapp(HttpServletRequest request, HttpServletResponse response,String name) {
    Apps apps=dao.fetch(Apps.class, Cnd.where("linkId", "=", name));
    if(apps!=null){
       return Result.success()
       }else{
       return Result.fail("无app下载数据");
    }
}
这个我应该怎么设置  不是@Fail吗？
