我使用AdoNetAppender
将日志写入数据库
连接很好,因为我看到记录器已连接到数据库
此外,如果我在连接中更改数据库名称,我可以在log4net跟踪中看到错误,因此连接良好,但数据库表仍然是空的。
这是配置文件:
<log4net>
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="100" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="data source=(localdb)\MSSQLLocalDB;initial catalog=LogsAffiliatePortal;integrated security=true;persist security info=True;" />
<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>
<parameter>
<parameterName value="@log_level" />
<dbType value="String" />
<size value="50" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level" />
</layout>
</parameter>
<parameter>
<parameterName value="@logger" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%logger" />
</layout>
</parameter>
<parameter>
<parameterName value="@message" />
<dbType value="String" />
<size value="4000" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message" />
</layout>
</parameter>
<parameter>
<parameterName value="@exception" />
<dbType value="String" />
<size value="2000" />
<layout type="log4net.Layout.ExceptionLayout" />
</parameter>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="AdoNetAppender" />
</root>
</log4net>
以下是我如何使用日志:
public class Global : HttpApplication
{
private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
void Application_Start(object sender, EventArgs e)
{
var configFile = ConfigurationManager.AppSettings.Get("MyLog4NetConfigFile");
if (!string.IsNullOrEmpty(configFile))
{
var f = HostingEnvironment.ApplicationPhysicalPath +Environment.ExpandEnvironmentVariables(configFile);
XmlConfigurator.Configure(new FileInfo(f));
}
log.Debug("yes");
log.Error("test");
}
}
答案 0 :(得分:0)
一个常见问题是您希望有一条日志消息,但log4net正在缓冲。将bufferSize更改为1:
<bufferSize value="1" />
将直接记录所有消息。
