一、能够使用Control中的AOP实现非业务需求的功能
一、ActionFilterAttribute类
二、实现自定义Attribute
1 using System;
2
3 namespace System.Web.Mvc
4 {
5 // Summary:
6 // Represents the base class for filter attributes.
7 [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false)]
8 public abstract class ActionFilterAttribute : FilterAttribute, IActionFilter, IResultFilter
9 {
10 // Summary:
11 // Initializes a new instance of the System.Web.Mvc.ActionFilterAttribute class.
12 protected ActionFilterAttribute();
13
14 // Summary:
15 // Called by the ASP.NET MVC framework after the action method executes.
16 //
17 // Parameters:
18 // filterContext:
19 // The filter context.
20 public virtual void OnActionExecuted(ActionExecutedContext filterContext);
21 //
22 // Summary:
23 // Called by the ASP.NET MVC framework before the action method executes.
24 //
25 // Parameters:
26 // filterContext:
27 // The filter context.
28 public virtual void OnActionExecuting(ActionExecutingContext filterContext);
29 //
30 // Summary:
31 // Called by the ASP.NET MVC framework after the action result executes.
32 //
33 // Parameters:
34 // filterContext:
35 // The filter context.
36 public virtual void OnResultExecuted(ResultExecutedContext filterContext);
37 //
38 // Summary:
39 // Called by the ASP.NET MVC framework before the action result executes.
40 //
41 // Parameters:
42 // filterContext:
43 // The filter context.
44 public virtual void OnResultExecuting(ResultExecutingContext filterContext);
45 }
46 }
OnActionExecuting：在Action执行之前执行该方法
OnActionExecuted：在Action执行之后执行该方法
OnResultExecuting：在Result执行之前执行该方法
OnResultExecuted：在Result执行之后执行该方法
1.代码
1 using System.Web.Mvc;
2
3 namespace MVC3.Demo.App_Code
4 {
5 public class LogActionFilter : ActionFilterAttribute
6 {
7 public string LogMessage { get; set; }
8
9 public override void OnActionExecuting(ActionExecutingContext filterContext)
10 {
11 filterContext.HttpContext.Response.Write(@"在Action执行之前执行" + LogMessage + "<br />");
12 base.OnActionExecuting(filterContext);
13 }
14
15 public override void OnActionExecuted(ActionExecutedContext filterContext)
16 {
17 filterContext.HttpContext.Response.Write(@"在Action执行之后执行" + LogMessage + "<br />");
18 base.OnActionExecuted(filterContext);
19 }
20
21 public override void OnResultExecuting(ResultExecutingContext filterContext)
22 {
23 filterContext.HttpContext.Response.Write(@"在Result执行之前执行" + LogMessage + "<br />");
24 base.OnResultExecuting(filterContext);
25 }
26
27 public override void OnResultExecuted(ResultExecutedContext filterContext)
28 {
29 filterContext.HttpContext.Response.Write(@"在Result执行之后执行" + LogMessage + "<br />");
30 base.OnResultExecuted(filterContext);
31 }
32 }
33 }
2.使用
1 [LogActionFilter(LogMessage = "日志写入：Validation方法")]
2 public ActionResult Validation()
3 {
4 return View();
5 }
3.效果
做笔记使用
