生成Log日志文件.NE

首先创建一个log4net.config的文件，在文件里面设置如下：

<?xml version="1.0" encoding="utf-8"?>

<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
  </configSections>
  <log4net>

    <logger name="LogSystem">
      <level value="ALL"/>
      <!--<appender-ref ref="AdoNetAppender_SqlServer" />-->
      <appender-ref ref="rollingFile" />
    </logger>

    <!--<root>
            <level value="OFF"/>
            <appender-ref ref="AdoNetAppender_SqlServer"/>
        </root>-->

    <!--记录到文件方式-->
    <appender name="rollingFile" type="log4net.Appender.RollingFileAppender,log4net" >
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <!--Log/文件夹下面的 以时间命名的文件 -->
      <param name="File" type="" value="Log/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <param name="DatePattern" value="yyyyMMdd'.txt'" />
      <param name="StaticLogFileName" value="false" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} | [%t] | %-5p | %c | %m%n" />
      </layout>
    </appender>
    <!--记录到sqlserver数据库方式-->
    <!--<appender name="AdoNetAppender_SqlServer" type="log4net.Appender.AdoNetAppender">
            <buffersize value="1" />
            <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
             <connectionString value="server=192.168.0.181;database=TopSystem;uid=TOPUSER;pwd=TOPSYS2010;"/>

                <parameterName value="@log_date"/>
                <dbType value="DateTime"/>
                <layout type="log4net.Layout.PatternLayout" value="%date{yyyy'-'MM'-'dd HH':'mm':'ss'.'fff}"/>
            </parameter>
            <parameter>
                <parameterName value="@thread"/>
                <dbType value="String"/>
                <size value="255"/>
                <layout type="log4net.Layout.PatternLayout" value="%thread"/>
            </parameter>

                <size value="4000"/>

            </parameter>
        </appender>-->
  </log4net>
</configuration>

在web.config配置：

<appSettings>
<!-- 作业调度配置 -->
<add key="cronExpr" value="00 18 16 ? * *"/>
</appSettings>

在global.asax配置如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;
using System.Configuration;

namespace Webcode
{
    public class Global : System.Web.HttpApplication
    {
        Quartz.IScheduler sched;
        protected void Application_Start(object sender, EventArgs e)
        {
            ComLib.LogLib.Log4NetBase.Log("程序启动");
            //在应用程序启动时运行的代码
            Quartz.ISchedulerFactory sf = new Quartz.Impl.StdSchedulerFactory();
            sched = sf.GetScheduler();
            Quartz.JobDetail job = new Quartz.JobDetail("daily", "dailygroup", typeof(Webcode.BussniesLogic.Service.QuartzJobService));
            string cronExpr = ConfigurationManager.AppSettings["cronExpr"];
            Quartz.CronTrigger trigger = new Quartz.CronTrigger("daily_trigger", "dailygroup", "daily", "dailygroup", cronExpr);
            sched.AddJob(job, true);
            DateTime ft = sched.ScheduleJob(trigger);
            sched.Start();
            ComLib.LogLib.Log4NetBase.Log("程序启动结束");
        }

        protected void Session_Start(object sender, EventArgs e)
        {

        }

        protected void Application_BeginRequest(object sender, EventArgs e)
        {

        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {

        }

        protected void Application_Error(object sender, EventArgs e)
        {
            
        }

        protected void Session_End(object sender, EventArgs e)
        {

        }

        protected void Application_End(object sender, EventArgs e)
        {

        }
    }
}

本人不喜欢LOG文件记录太多没必要的信息，如果需要每次都记录可以在Application_Error里面添加：

 protected void Application_Error(object sender, EventArgs e)
{
Exception ex = Server.GetLastError().GetBaseException();

         if (ex != null)
        {
             ComLib.LogLib.Log4NetBase.Log(string.Format(@"错误的信息{0}--出错的方法名{1}--
               出错的类名{2}", ex.Message, ex.TargetSite.Name, ex.TargetSite.DeclaringType.FullName));
           }
            // 清空最后的错误
          Server.ClearError();
           Response.Redirect("/operate/error.htm");
}

public class QuartzJobService : IJob
    {
        #region IJob Members

        public void Execute(JobExecutionContext context)
        {
            ComLib.LogLib.Log4NetBase.Log("Job开始:" + DateTime.Now);
            DbSession.Default.FromProc("Report_Daily_Job").Execute();
            ComLib.LogLib.Log4NetBase.Log("JobReport_Daily_Job:" + DateTime.Now);
            DbSession.Default.FromProc("Report_Daily_TSL").Execute();
            ComLib.LogLib.Log4NetBase.Log("JobReport_Daily_TSL:" + DateTime.Now);
            DbSession.Default.FromProc("Report_Daily_ShortKey_TSL").Execute();
            ComLib.LogLib.Log4NetBase.Log("JobReport_Daily_ShortKey_TSL:" + DateTime.Now);
        }

        #endregion
    }

QuartzJobService.cs的代码如上

由于本人所用的框架限制不能黏贴太多代码，也是新手一枚，如果需要帮助请留言~欢迎大家批评共同进步
