我是log4net记录器的新手,我正在尝试使用AdoNetAppender创建记录器以将日志保存到数据库中。
当我使用简单布局
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
并保存到数据库:
<commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
<parameter>
<parameterName value="@log_date" />
<dbType value="DateTime" />
<layout type="log4net.Layout.RawTimeStampLayout" />
</parameter>
<parameter>
<parameterName value="@thread" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%thread" />
</layout>
</parameter>
它成功保存到数据库;问题是我需要注册更多详细信息(位置,方法,行),但无法将其保存在数据库中。
为此,我使用了以下配置:
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger %location
%method %line - %message %newline" />
</layout>
对于数据库插入:
<commandText value="INSERT INTO Log( [Date],[Thread],[Level],[Logger],
[Locaotion],[Method],[Line],[Message],[Exception])
VALUES (@log_date, @thread, @log_level,
@logger,@location @method, @line, @message, @exception)" />
<parameter>
<parameterName value="@location" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%location" />
</layout>
</parameter>
<parameter>
<parameterName value="@method" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%method" />
</layout>
</parameter>
<parameter>
<parameterName value="@line" />
<dbType value="String" />
<size value="50" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%line" />
</layout>
</parameter>
我的C#代码:
private static ILog log = LogManager.GetLogger(typeof(HomeController));
//private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
如何将完整的错误详细信息保存在数据库中?
答案 0 :(得分:1)
我得到的错误是我忘记了数据库插入代码中的(,),而我在全局中添加了Application_Error
conversionPattern代码:
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%location] [%method] [%line] - %message %newline" />
</layout>
数据库插入代码:
<commandText value="INSERT INTO Log( [Date],[Thread],[Level],[Logger],[Location],[Method],[Line],[Message],[Exception])
VALUES (@log_date, @thread, @log_level, @logger, @location, @method, @line, @message, @exception)" />
以及全局代码:
private static readonly ILog log = LogManager.GetLogger(typeof(MvcApplication));
private void Application_Error(Object sender, EventArgs e)
{
var ex = Server.GetLastError().GetBaseException();
log.Error("App_Error", ex);
}
