1、安装依赖
2、配置文件
3、注册组件
4、使用
1、安装依赖Microsoft.Extensions.Logging.Log4Net.AspNetCore
2、配置文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<!-- This section contains the log4net configuration settings -->
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout" value="%date [%thread] %-5level %logger - %message%newline" />
</appender>
<appender name="FileAppender" type="log4net.Appender.FileAppender">

<datePattern value="yyyyMMdd'.log'" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="1MB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<!--配置该节点会监听的日志错误级别-->
<levelMax value="FATAL" />
</filter>
</appender>
<appender name="WarnRollingFileAppender" type="log4net.Appender.RollingFileAppender">

</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="TRACE " />
<levelMax value="INFO" />
</filter>
</appender>
<!-- Setup the root category, add the appenders and set the default level -->
<root>
<level value="ALL" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="FileAppender" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="WarnRollingFileAppender" />
<appender-ref ref="InfoRollingFileAppender" />
</root>
</log4net>
</configuration>
3、注册组件
Program.cs文件中
ILoggerRepository repository = LogManager.CreateRepository("NETCoreRepository");
XmlConfigurator.Configure(repository, new FileInfo("log4net.config"));
4、使用
/// <summary>
/// 日志
/// </summary>
public ILog log = LogManager.GetLogger("NETCoreRepository", this.GetType());
文件生成在项目bin\Debug\net6.0\LogFile\目录下
