log4net 不记录调试语句

本文关键字:语句 调试 记录 log4net | 更新日期: 2023-09-27 18:34:54

我是第一次使用 log4net,并且使用提供的配置示例遵循了文档,但是调试语句不会记录。

信息、错误、警告和致命级别都正确记录。谁能告诉我我错过了什么?

app.config:

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
<log4net>
    <appender name="Console" type="log4net.Appender.ColoredConsoleAppender">
        <mapping>
            <level value="INFO" />
            <foreColor value="Green"/>
        </mapping>
        <mapping>
            <level value="DEBUG" />
            <foreColor value="Cyan,HighIntensity"/>
        </mapping>
        <mapping>
            <level value="WARN" />
            <foreColor value="Purple,HighIntensity"/>
        </mapping>
        <mapping>
            <level value="ERROR" />
            <foreColor value="Red,HighIntensity"/>
        </mapping>
        <mapping>
            <level value="FATAL" />
            <foreColor value="Yellow,HighIntensity"/>
        </mapping>
        <layout type="log4net.Layout.PatternLayout">
            <!-- Pattern to output the caller's file name and line number -->
            <conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
        </layout>            
    </appender>
    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
        <file value="example.log" />
        <appendToFile value="true" />
        <maximumFileSize value="100KB" />
        <maxSizeRollBackups value="2" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%level %thread %logger - %message%newline" />
        </layout>
    </appender>
    <root>
        <level value="INFO" />
        <appender-ref ref="Console" />
        <appender-ref ref="RollingFile" />
    </root>
</log4net>

有些人提到检查AssemblyInfo的[assembly: log4net.Config.XmlConfigurator((],但是有或没有这一行没有区别。

记录器声明如下:

private static readonly ILog log = LogManager.GetLogger( typeof( CWD_Netsuite ) );

并按以下方式访问:

XmlConfigurator.Configure();
log.Debug("Debugging");             //does not get logged
log.Info( "Entering Application" ); //logged to console and log file
log.Debug( "Debug Statement" );     //does not get logged 
log.Error( "Error statement" );     //logged to console and log file
log.Warn( "Warning statement" );    //logged to console and log file
log.Fatal( "Fatal Statement" );     //logged to console and log file

log4net 不记录调试语句

您在根类别中设置了一个过滤器INFO级别(从而过滤掉DEBUG级别的任何邮件(:

<root>
    <level value="INFO" />
    <appender-ref ref="Console" />
    <appender-ref ref="RollingFile" />
</root>

将其更改为

    <level value="DEBUG" />

log4net 级别按以下顺序定义:

都调试信息警告错误致命关闭

根据您当前的设置,您将使用 INFO 及以下版本编写所有内容。

将根节点设置为以下内容:

<root>
    <level value="DEBUG" />
    <appender-ref ref="Console" />
    <appender-ref ref="RollingFile" />
</root>

节点中的级别值更改为"调试"...

<root>
    <level value="DEBUG" />
    <appender-ref ref="Console" />
    <appender-ref ref="RollingFile" />
</root>
