网上关于log4net日志写入mysql数据库的博客感觉比较少,所以这边搞定之后先过来记录一下。
首先新建个项目,我命名是log4netDemo,然后需要引入两个dll,一个是mysql.dll,一个是log4net.dll。可以通过NuGet安装这两个dll,如下图
我这边mysql和log4net的版本分别是6.10.8和2.0.8,当然mysql更高版本的也是可以的。
然后在项目中新建一个log4net.config的配置文件,配置全文如下:
<?xml version="1.0"?> <configuration> <system.web> <compilation debug="true" targetFramework="4.5" /> <httpRuntime targetFramework="4.5" /> </system.web> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <appender name="AdoNetAppender_MySql" type="log4net.Appender.AdoNetAppender"> <bufferSize value="1" /> <param name="ConnectionType" value="MySql.Data.MySqlClient.MySqlConnection, MySql.Data"/> <param name="ConnectionString" value="server=localhost;database=test_log4net;Uid=root;Pwd=123456;port=3306;"/> <commandText value="INSERT INTO loggermall (`log_thread`,`log_level`,`log_logger`,`log_message`) VALUES (@log_thread,@log_level,@log_logger,@log_message)" /> <parameter> <parameterName value="@log_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="%-5level"/> </layout> </parameter> <parameter> <parameterName value="@log_logger"/> <dbType value="String"/> <size value="50"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%logger"/> </layout> </parameter> <parameter> <parameterName value="@log_message"/> <dbType value="String"/> <size value="4000"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%message"/> </layout> </parameter> </appender> <!--错误日志--> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="log\\LogError\\"/> <appendToFile value="true"/> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <rollingStyle value="Date"/> <datePattern value="yyyy\\yyyyMM\\yyyyMMdd‘.txt‘"/> <staticLogFileName value="false"/> <param name="MaxSizeRollBackups" value="100"/> <layout type="log4net.Layout.PatternLayout"> <!--每条日志末尾的文字说明--> <!--输出格式--> <!--样例:2008-03-26 13:42:32,111 [10] INFO Log4NetDemo.MainClass [(null)] - info--> <conversionPattern value="%newline %n记录时间:%date %n线程ID:[%thread] %n日志级别: %-5level %n错误描述:%message%newline %n"/> </layout> </appender> <!--Info日志--> <appender name="InfoAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="Log\\LogInfo\\" /> <param name="AppendToFile" value="true" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <param name="MaxFileSize" value="10240" /> <param name="MaxSizeRollBackups" value="100" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="yyyy\\yyyyMM\\yyyyMMdd‘.txt‘" /> <param name="RollingStyle" value="Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%newline %n记录时间:%date %n线程ID:[%thread] %n日志级别: %-5level %n日志描述:%message%newline %n"/> </layout> </appender> <!--监控日志--> <appender name="MonitorAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="Log\\LogMonitor\\" /> <param name="AppendToFile" value="true" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <param name="MaxFileSize" value="10240" /> <param name="MaxSizeRollBackups" value="100" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="yyyy\\yyyyMM\\yyyyMMdd‘.txt‘" /> <param name="RollingStyle" value="Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%newline %n记录时间:%date %n线程ID:[%thread] %n日志级别: %-5level %n跟踪描述:%message%newline %n"/> </layout> </appender> <!--Error日志--> <logger name="logerror"> <level value="ERROR" /> <appender-ref ref="AdoNetAppender_MySql"/> <appender-ref ref="RollingLogFileAppender" /> </logger> <!--Info日志--> <logger name="loginfo"> <level value="INFO" /> <appender-ref ref="AdoNetAppender_MySql"/> <appender-ref ref="InfoAppender" /> </logger> <!--监控日志--> <logger name="logmonitor"> <level value="WARN" /> <appender-ref ref="AdoNetAppender_MySql"/> <appender-ref ref="MonitorAppender" /> </logger> </log4net> </configuration>
其中appender中Name为AdoNetAppender_MySql的配置是配置连接数据库的类型、连接字符串及插入数据库的语句、语句对应的值等配置信息。
然后建立类代码如下:
using System; using System.Collections.Generic; namespace Log4NetDemo { /// <summary> /// 日志配置 /// </summary> public static class LogConfig { /// <summary> /// 异常日志语句 /// </summary> /// <param name="ControllerName"></param> /// <param name="ActionName"></param> /// <param name="ActionParams"></param> /// <param name="HttpRequestHeaders"></param> /// <param name="HttpMethod"></param> /// <param name="ip"></param> /// <returns></returns> public static string GetLogErrorString(string ControllerName = null, string ActionName = null, Dictionary<string, object> ActionParams = null, string HttpRequestHeaders = null, string HttpMethod = null, string ip = null) { return $@" 请求【{ControllerName}Controller】的【{ActionName}】 产生异常: Action参数:{GetCollections(ActionParams)} Http请求头:{HttpRequestHeaders} ip地址:{ip}, 请求类型:{HttpMethod}"; } /// <summary> /// 获取Action 参数 /// </summary> /// <param name="Collections"></param> /// <returns></returns> public static string GetCollections(Dictionary<string, object> Collections) { string Parameters = string.Empty; if (Collections == null || Collections.Count == 0) { return Parameters; } foreach (string key in Collections.Keys) { Parameters += $"{key}={Collections[key]}&"; } if (!string.IsNullOrWhiteSpace(Parameters) && Parameters.EndsWith("&")) { Parameters = Parameters.Substring(0, Parameters.Length - 1); } return Parameters; } } /// <summary> /// 日志配置 /// </summary> public class LoggerWebConfig { /// <summary> /// 控制器 /// </summary> public string ControllerName { get; set; } /// <summary> /// 方法 /// </summary> public string ActionName { get; set; } /// <summary> /// 开始时间 /// </summary> public DateTime ExecuteStartTime { get; set; } /// <summary> /// 结束时间 /// </summary> public DateTime ExecuteEndTime { get; set; } /// <summary> /// 请求的Action 参数 /// </summary> public Dictionary<string, object> ActionParams { get; set; } /// <summary> /// Http请求头 /// </summary> public string HttpRequestHeaders { get; set; } /// <summary> /// 请求方式 /// </summary> public string HttpMethod { get; set; } /// <summary> /// 请求的IP地址 /// </summary> public string IP { get; set; } /// <summary> /// 返回监控语句 /// </summary> /// <param name="mtype"></param> /// <returns></returns> public string GetInfoString() { string Msg = $@" Action执行时间监控: 控制器名:{ControllerName} 访问方法: {ActionName} 开始时间:{ExecuteStartTime} 结束时间:{ExecuteEndTime} 总耗时间:{(ExecuteEndTime - ExecuteStartTime).TotalSeconds}秒 请求参数:{LogConfig.GetCollections(ActionParams)} 请求头部: {HttpRequestHeaders} 请求地址:{IP} 请求方式: {HttpMethod}"; return Msg; } } }
以上类建好之后,建立一个Loggerhelper用来加载配置信息重写写入相应的日志信息的方法。
using System; using log4net; [assembly: log4net.Config.XmlConfigurator(ConfigFile = "~/Log4net.config", Watch = true)] namespace Taihua.Log4 { /// <summary> /// 日志 /// </summary> public class LoggerHelper { /// <summary> /// 定义日志模块 /// </summary> private static readonly ILog loginfo = LogManager.GetLogger("loginfo"); private static readonly ILog logerror = LogManager.GetLogger("logerror"); private static readonly ILog logwarn = LogManager.GetLogger("logmonitor"); /// <summary> /// 错误日志 /// </summary> /// <param name="ErrorMsg">错误信息</param> /// <param name="ex">异常</param> public static void Error(string ErrorMsg, Exception ex = null) { if (ex != null) { logerror.Error(ErrorMsg, ex); } else { logerror.Error(ErrorMsg); } } /// <summary> /// 警告日志 /// </summary> /// <param name="Msg">错误信息</param> public static void Info(string Msg) { loginfo.Info(Msg); } /// <summary> /// 监控日志 /// </summary> /// <param name="Msg">错误信息</param> public static void Warn(string Msg) { logwarn.Warn(Msg); } } }
在需要记录日志的地方使用如下代码调用
LoggerHelper.Info($"测试测试"); LoggerHelper.Warn($"警告测试警告测试"); LoggerHelper.Error($"错误测试错误测试");
最后建立一个demo数据库及log4net的数据库表,数据库表代码如下:
DROP TABLE IF EXISTS `loggerbackstage`; CREATE TABLE `loggerbackstage` ( `id` int(11) NOT NULL AUTO_INCREMENT, `log_datetime` timestamp(0) NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP(0), `log_thread` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL, `log_level` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL, `log_logger` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL, `log_message` text CHARACTER SET utf8 COLLATE utf8_general_ci, PRIMARY KEY (`id`) USING BTREE ) ENGINE = InnoDB AUTO_INCREMENT = 16 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;
然后就log4net日志就可以记录到文本文件中和数据库中了。如果警告、错误、信息需要记录到不同的表中,那么需要配置不同的append节点,并且调用。

等博客,看得太多不一定记得下来。大致就是这两篇吧,另外配置数据库连接方式的时候不要指定mysql的版本 ,因为我指定版本的时候写不进去,不知道是什么原因。还有一点就是配置文件中的
<bufferSize value="1" />
是代表缓存大小,在没达到缓存大小时,暂时不会存到数据库中,当程序关闭之后会,将未插入数据库的记录加入到数据库中。
