• log4net简单用法


    一、NuGet在Server,mvc中添加Common.Logging和common.Logging.Log4Net如下图

    二、在Server层创建logger类

    <?xml version="1.0" encoding="utf-8" ?>
    <log4net>
      <!--级别层级ALL<DEBUG<INFO<WARN<ERROR<FATAL<OFF -->
      <!--调试日志-->

    三、在mvc项目中添加log4net.config

    using System;
    using System.Collections.Generic;
    using System.Diagnostics;
    using System.IO;
    using System.Reflection;
    using System.Text;

            public static void Debug(IFormatProvider formatProvider, Action<Common.Logging.FormatMessageHandler> formatMessageCallback, Exception exception)

            }
    
            public static void Debug(Action<Common.Logging.FormatMessageHandler> formatMessageCallback, Exception exception)

    }

    四、在web.config的<configSections>内部添加

     <sectionGroup name="common">
          <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
        </sectionGroup>

    五、在web.config的</configSections>的后面添加

    <common>
        <logging>
          <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net">
            <arg key="configType" value="FILE-WATCH" />
            <!-- FILE,FILE-WATCH,INLINE,EXTERNAL-->
            <arg key="configFile" value="~/log4net.config" />
            <arg key="level" value="ALL" />
          </factoryAdapter>
        </logging>
      </common>

    六、创建测试类Class1进行调用所有类结构如下图
