log4net 发布后不写log

[LoveJava520]

1.使用vs2008测试时可以写log的，但发布到iis就不写log了
2.代码如下，大家帮忙看些，tks!
(1)web.config文件
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="log4net" type="System.Configuration.IgnoreSectionHandler"/>
</configSections>
<appSettings>
</appSettings>
<log4net>
<!--定义输出到文件中-->
<appender name="LogFileAppender" type="log4net.Appender.FileAppender">
<!--定义文件存放位置-->
<file value="D:\\aa.txt"/>
<appendToFile value="true"/>
<rollingStyle value="Date"/>
<datePattern value="yyyyMMdd-HH:mm:ss"/>
<layout type="log4net.Layout.PatternLayout">
<!--每条日志末尾的文字说明-->
<footer value="by 周公"/>
<!--输出格式-->
<!--样例：2008-03-26 13:42:32,111 [10] INFO Log4NetDemo.MainClass [(null)] - info-->
<conversionPattern value="记录时间：%date 线程ID:[%thread] 日志级别：%-5level 出错类：%logger property:[%property{NDC}] - 错误描述：%message%newline"/>
</layout>
</appender>
<!--定义输出到控制台命令行中-->
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
</layout>
</appender>
<!--定义输出到windows事件中-->
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
</layout>
</appender>
<!--定义输出到数据库中，这里举例输出到Access数据库中，数据库为C盘的log4net.mdb-->
<!--<appender name="AdoNetAppender_Access" type="log4net.Appender.AdoNetAppender">
<connectionString value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:log4net.mdb" />
<commandText value="INSERT INTO LogDetails ([LogDate],[Thread],[Level],[Logger],[Message]) VALUES (@logDate, @thread, @logLevel, @logger,@message)" />
--><!--定义各个参数--><!--
<parameter>
<parameterName value="@logDate" />

</appender>-->
<!--定义日志的输出媒介，下面定义日志以四种方式输出。也可以下面的按照一种类型或其他类型输出。-->
<root>
<!--文件形式记录日志-->
<appender-ref ref="LogFileAppender"/>
<!--控制台控制显示日志-->
<appender-ref ref="ConsoleAppender"/>
<!--Windows事件日志-->
<appender-ref ref="EventLogAppender"/>
<!-- 如果不启用相应的日志记录，可以通过这种方式注释掉
<appender-ref ref="AdoNetAppender_Access" />
-->
</root>
</log4net>
<system.web>
<compilation debug="true"/></system.web></configuration>



2.writer log类
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using log4net;
using System.Reflection;
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
/// <summary>
/// Summary description for WriteLog
/// </summary>

public class WriteLog
{
ILog log = null;
public WriteLog()
{
//
// TODO: Add constructor logic here
//
log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

}
public void Debug(String msg)
{
log.Debug(msg);
}

public void Info(String msg)
{
log.Info(msg);
}

public void Warn(String msg)
{
log.Warn(msg);
}

public void Error(String msg)
{
log.Error(msg);
}

}


3.测试类
using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

public partial class _Default : System.Web.UI.Page
{
// log4net.Config.DOMConfigurator.Configure();
// private static readonly log4net.ILog log = log4net.LogManager.GetLogger(typeof(_Default));

protected void Page_Load(object sender, EventArgs e)
{


}
protected void Button1_Click(object sender, EventArgs e)
{
WriteLog wl = new WriteLog();
wl.Info("ddddddd");
wl.Error("111111111");
}



}

发布到IIS之后，该代码运行在工作进程账号下面，估计是没权限往D盘下面写东西的。学习一下IIS的进程模型吧，找到工作进程的账号，给它写D盘的权限就好了。

简单的测试方法是建立D:\logs文件夹，赋予Everyone写权限，然后配置log4net往这里面写日志，那么你就能看到日志文件了。
