mvc-百步飞剑-06
说明:LogForNet,操作之前建议阅读mvc中简单的异常记录
1.1 在WebApp的Model中 添加异常处理类 继承于HandleErrorAttribute
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace BBFJ.OA.WebApp.Models { public class MyExceptionAttribute:HandleErrorAttribute { public static Queue<Exception> ExceptionQueue = new Queue<Exception>(); /// <summary> /// 捕获异常信息 /// 别忘了在在异常处理过滤器中注册一下 /// </summary> /// <param name="filterContext"></param> public override void OnException(ExceptionContext filterContext) { base.OnException(filterContext); //捕获异常信息 Exception ex = filterContext.Exception; //写到日志时,多个线程同时访问,会造成并发,形成死锁===>写入队列 ExceptionQueue.Enqueue(ex); //跳转到错误页 filterContext.HttpContext.Response.Redirect("/Error.html"); } } } MyExceptionAttribute
1.2 在WebApp下App_Start的FilterConfig异常处理过滤器中注册一下
using BBFJ.OA.WebApp.Models; using System.Web; using System.Web.Mvc; namespace BBFJ.OA.WebApp { public class FilterConfig { //在异常处理过滤器中注册一下 public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new MyExceptionAttribute()); } } } RegisterGlobalFilters
1.3 在WebApp中添加错误页面Error.html
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> </head> <body> 服务器忙,5秒钟后跳转到首页! </body> </html>
1.4 WebApp中引用Log4net(百度云盘)
1.5在WebConfig文件中加入配置信息

1.6 初始化：在程序最开始加入log4net.Config.XmlConfigurator.Configure();在日志记录的地方 ILog logger=LogManager.GetLogger("errorMsg")
using BBFJ.OA.WebApp.Models; using log4net; using Spring.Web.Mvc; using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Threading; using System.Web; using System.Web.Http; using System.Web.Mvc; using System.Web.Optimization; using System.Web.Routing; namespace BBFJ.OA.WebApp { // 注意: 有关启用 IIS6 或 IIS7 经典模式的说明， // 请访问 http://go.microsoft.com/?LinkId=9394801 //SpringMvcApplication继承了System.Web.HttpApplication //通过SpringMvcApplication中的ConfigureApplicationContext();方法,读取配置文件创建IHttpApplication容器 public class MvcApplication : SpringMvcApplication //System.Web.HttpApplication { protected void Application_Start() { //在程序启动时读取了配置文件中关于log4Net的配置信息 log4net.Config.XmlConfigurator.Configure(); AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); //开启线程,扫描异常 //建立日志文件夹,拿到物理路径 string filePath = Server.MapPath("/Log/"); //线程池中取线程 ThreadPool.QueueUserWorkItem((a) => { while (true) { //检查异常队列中是否有数据 if (MyExceptionAttribute.ExceptionQueue.Count() > 0) { Exception ex= MyExceptionAttribute.ExceptionQueue.Dequeue(); if (ex != null) { //将异常写入日志文件 // string fileName = DateTime.Now.ToString("yyyy-MM-dd"); // File.AppendAllText(filePath+fileName+".txt",ex.ToString(),System.Text.Encoding.UTF8); //引用using log4net; ILog logger = LogManager.GetLogger("errorMsg"); //将异常信息写入日志 //只存错误信息,不存堆栈信息 logger.Error(ex.Message); logger.Error(ex.ToString()); } else { Thread.Sleep(3000); } } else { //很重要,如果队列中没有数据休息一会 Thread.Sleep(3000); } } }, filePath); } } }
