可以声明一个自定义控制器BaseController继承Controller重写Controller中的OnActionExecuting虚方法，然后其他控制器继承BaseController就可以，避免了给每个控制器打个过滤标签去验证
public class BaseController : Controller
{
public UserInfo LoginUser { get; set; }
/// <summary>
/// 执行控制器中的方法之前先执行该方法。
/// </summary>
/// <param name="filterContext"></param>
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
base.OnActionExecuting(filterContext);
//if (Session["userInfo"] == null)
bool isSucess = false;
if(Request.Cookies["sessionId"]!=null)
{
string sessionId = Request.Cookies["sessionId"].Value;
//根据该值查Memcache.
object obj=Common.MemcacheHelper.Get(sessionId);
if(obj!=null)
{
UserInfo userInfo = Common.SerializeHelper.DeserializeToObject<UserInfo>(obj.ToString());
LoginUser = userInfo;
isSucess = true;
Common.MemcacheHelper.Set(sessionId, obj, DateTime.Now.AddMinutes(20));//模拟出滑动过期时间.
//留一个后门，测试方便。发布的时候一定要删除该代码。
if (LoginUser.UName == "itcast")
{
return;
}
//完成权限校验。
//获取用户请求的URL地址.
string url = Request.Url.AbsolutePath.ToLower();
//获取请求的方式.
string httpMehotd = Request.HttpMethod;
//根据获取的URL地址与请求的方式查询权限表。
IApplicationContext ctx = ContextRegistry.GetContext();
IBLL.IActionInfoService ActionInfoService = (IBLL.IActionInfoService)ctx.GetObject("ActionInfoService");
var actionInfo= ActionInfoService.LoadEntities(a=>a.Url==url&&a.HttpMethod==httpMehotd).FirstOrDefault();
if (actionInfo != null)
{
filterContext.Result = Redirect("/Error.html");
return;
}
//判断用户是否具有所访问的地址对应的权限
IUserInfoService UserInfoService = (IUserInfoService)ctx.GetObject("UserInfoService");
var loginUserInfo = UserInfoService.LoadEntities(u=>u.ID==LoginUser.ID).FirstOrDefault();
//1:可以先按照用户权限这条线进行过滤。
var isExt =(from a in loginUserInfo.R_UserInfo_ActionInfo

if (isExt != null)
{
if (isExt.IsPass)
{
return;
}
else

filterContext.Result = Redirect("/Error.html");

//2：按照用户角色权限这条线进行过滤。
