MVC里面的Filter public class AOPFilterAttribute : ActionFilterAttribute, IExceptionFilter { public void OnException(ExceptionContext filterContext) { throw new System.NotImplementedException(); } public override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); } public override void OnActionExecuted(ActionExecutedContext filterContext) { base.OnActionExecuted(filterContext); } } 在controller里面使用该特性: [AOPFilter] public JsonResult GetEditModel(string strType) { var lstRes = new List<List<DragElementProp>>(); var lstResPage = new List<PageProperty>(); //.........todo return Json(new { lstDataAttr = lstRes, PageAttr = lstResPage, lstJsConnections = lstJsPlumbLines }, JsonRequestBehavior.AllowGet); } 调试可知,在执行GetEditModel(string strType)方法之前,会先执行OnActionExecuting()方法,GetEditModel(string strType)之后,又会执行OnActionExecuted()方法。这在我们MVC里面权限验证、错误页导向、日志记录等常用功能都可以方便解决
