MVC下的全局异常过滤器注册方式如下：标红为asp.net mvc ，asp.net mvc api 注册全局异常过滤器的不同之处
using SuperManCore;
using System.Web;
using System.Web.Mvc;
namespace SuperMan
{
public class FilterConfig
{
/// <summary>
/// 注册全局过滤器 add by caoheyang 20150205
/// </summary>
/// <param name="filters"></param>
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new WebHandleErrorAttribute()， 1);
filters.Add(new HandleErrorAttribute()， 2);
}
}
/// <summary>
/// 自定义异常处理类 add by caoheyang 20150205
/// </summary>
public class WebHandleErrorAttribute : HandleErrorAttribute
{
/// <summary>
/// 重写异常处理方法 add by caoheyang 20150205 需要将该特性标注于各个controller上。
/// </summary>
/// <param name="filterContext">上下文对象 该类继承于ControllerContext</param>
public override void OnException(ExceptionContext filterContext)
{
LogHelper.LogWriterFromFilter(filterContext.Exception);
}
}
}
MVC API下的注册方式如下：
在WebApiConfig.cs文件下加入标红代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web.Http;
using Microsoft.Owin.Security.OAuth;
using Newtonsoft.Json.Serialization;
namespace SuperManWebApi
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务
// 将 Web API 配置为仅使用不记名令牌身份验证。
config.SuppressDefaultHostAuthentication();
config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
config.Filters.Add(new ApiHandleErrorAttribute()); //注册全局异常过滤器 add by caoheyang 20150206 不需要将该特性标注于各个controller上
// Web API 路由
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi"，
routeTemplate: "{controller}/{action}/{id}"，
defaults: new { id = RouteParameter.Optional }
);
}
}
}
/// <summary> /// 自定义异常处理类 add by caoheyang 20150205 不需要将该特性标注于各个controller上。 /// </summary> public class ApiHandleErrorAttribute : ExceptionFilterAttribute { /// <summary> /// 重写异常处理方法 add by caoheyang 20150205 /// </summary> /// <param name="filterContext">上下文对象 该类继承于ControllerContext</param> public override void OnException(HttpActionExecutedContext filterContext) { LogHelper.LogWriterFromFilter(filterContext.Exception); }
}
另外附LogHelper源码:
public class LogHelper
{
public static Logger logger = LogManager.GetLogger("SuperManCore.LogHelper");
/// <summary>
/// 备注日志
/// </summary>
/// <param name="dec">需要捕获的参数（必须为属性类）</param>
/// <param name="rmark">描述操作</param>
public new static void LogWriter(string rmark=""，object dec=null)
{
try
{
string logstr = "\r\n-----------------start----------------------\r\n";
MethodBase m = new StackTrace().GetFrame(1).GetMethod();
ParameterInfo[] pm = m.GetParameters();
string classname = m.DeclaringType.ToString();
string propertyName = m.Name;
logstr = logstr + "备注:" + rmark + "\r\n";
//写类名
logstr = logstr + "函数类名:" + classname + "\r\n";
//写函数方法
logstr = logstr + "函数名称为:" + propertyName + "\r\n";
for (int i = 0; i < pm.Length; i++)

}

logstr += "--------------------end---------------------\r\n";
//写日志
logger.Info(logstr);
}
catch (Exception)

throw;
