篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了log4net 发布到生产环境不写日志的解决方法相关的知识，希望对你有一定的参考价值。
1、升级到log4net的最新版
PM下执行
Install-Package log4net
还是无法解决的，使用下面的方法
2、使用Nlog替换之，详见https://github.com/NLog/NLog/wiki/Tutorial
安装
Install-Package NLog.Config
NLog使用方法比log4net更为简单，配置文件如下，如果成windows程序需将NLog.config自动复制到bin下面
1 <?xml version="1.0" encoding="utf-8" ?> 2 <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd" 5 autoReload="true" 6 throwExceptions="false" 7 internalLogLevel="Off" internalLogFile="F:\\temp\\20160907\\NLog\\log\\nlog-internal.log"> 8 9 <!-- optional, add some variables 10 https://github.com/nlog/NLog/wiki/Configuration-file#variables 11 --> 12 <variable name="myvar" value="myvalue"/> 13 14 <!-- 15 See https://github.com/nlog/nlog/wiki/Configuration-file 16 for information on customizing logging rules and outputs. 17 --> 18 <targets> 19 20 <!-- 21 add your targets here 22 See https://github.com/nlog/NLog/wiki/Targets for possible targets. 23 See https://github.com/nlog/NLog/wiki/Layout-Renderers for the possible layout renderers. 24 --> 25 26 <!-- 27 Write events to a file with the date in the filename. 28 <target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log" 29 layout="${longdate} ${uppercase:${level}} ${message}" /> 30 --> 31 <target name="logfile" xsi:type="File" fileName="${basedir}/logs/${shortdate}.log" /> 32 <target name="console" xsi:type="ColoredConsole" /> 33 </targets> 34 35 <rules> 36 <!-- add your logging rules here --> 37 38 <!-- 39 Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace) to "f" 40 <logger name="*" minlevel="Debug" writeTo="f" /> 41 --> 42 <logger name="*" minlevel="Debug" writeTo="logfile" /> 43 <logger name="*" minlevel="Info" writeTo="console" /> 44 </rules> 45 </nlog>
调用代码：
1 Logger logger = LogManager.GetCurrentClassLogger(); 2 3 4 logger.Trace("Sample trace message"); 5 logger.Debug("Sample debug message"); 6 logger.Info("Sample informational message"); 7 logger.Warn("Sample warning message"); 8 logger.Error("Sample error message"); 9 logger.Fatal("Sample fatal error message"); 10 11 12 logger.Info("wilson测试 日志日期：{0}", DateTime.Now);
执行结果，非常漂亮的控制台输出：
web站点配置log写入到sql server数据库，需要安装NLog.Web
Install-Package NLog.Web
配置文件如下
1 <?xml version="1.0" encoding="utf-8" ?> 2 <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd" 5 autoReload="true" 6 throwExceptions="false" 7 internalLogLevel="Off" internalLogFile="F:\\temp\\20160907\\NLog\\log\\nlog-internal.log"> 8 9 <!-- optional, add some variables 10 https://github.com/nlog/NLog/wiki/Configuration-file#variables 11 --> 12 <variable name="myvar" value="myvalue"/> 13 14 <!-- 15 See https://github.com/nlog/nlog/wiki/Configuration-file 16 for information on customizing logging rules and outputs. 17 --> 18 <targets> 19 20 <!-- 21 add your targets here 22 See https://github.com/nlog/NLog/wiki/Targets for possible targets. 23 See https://github.com/nlog/NLog/wiki/Layout-Renderers for the possible layout renderers. 24 --> 25 26 <!-- 27 Write events to a file with the date in the filename. 28 <target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log" 29 layout="${longdate} ${uppercase:${level}} ${message}" /> 30 --> 31 <target name="logfile" xsi:type="File" fileName="${basedir}/logs/${shortdate}.log" /> 32 <target name="console" xsi:type="ColoredConsole" /> 33 34 <target name="db" 35 xsi:type="Database" 36 connectionStringName="NLogConn" 37 commandType="StoredProcedure" 38 commandText="[dbo].[NLog_AddEntry_p]" 39 > 40 <parameter name="@machineName" layout="${machinename}" /> 41 <parameter name="@siteName" layout="${iis-site-name}" /> 42 <parameter name="@logged" layout="${date}" /> 43 <parameter name="@level" layout="${level}" /> 44 <parameter name="@username" layout="${aspnet-user-identity}" /> 45 <parameter name="@message" layout="${message}" /> 46 <parameter name="@logger" layout="${logger}" /> 47 <parameter name="@properties" layout="${all-event-properties:separator=|}" /> 48 <parameter name="@serverName" layout="${aspnet-request:serverVariable=SERVER_NAME}" /> 49 <parameter name="@port" layout="${aspnet-request:serverVariable=SERVER_PORT}" /> 50 <parameter name="@url" layout="${aspnet-request:serverVariable=HTTP_URL}" /> 51 <parameter name="@https" layout="${when:inner=1:when=\'${aspnet-request:serverVariable=HTTPS}\' == \'on\'}${when:inner=0:when=\'${aspnet-request:serverVariable=HTTPS}\' != \'on\'}" /> 52 <parameter name="@serverAddress" layout="${aspnet-request:serverVariable=LOCAL_ADDR}" /> 53 <parameter name="@remoteAddress" layout="${aspnet-request:serverVariable=REMOTE_ADDR}:${aspnet-request:serverVariable=REMOTE_PORT}" /> 54 <parameter name="@callSite" layout="${callsite}" /> 55 <parameter name="@exception" layout="${exception:tostring}" /> 56 </target> 57 58 59 </targets> 60 61 <rules> 62 <!-- add your logging rules here --> 63 64 <!-- 65 Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace) to "f" 66 <logger name="*" minlevel="Debug" writeTo="f" /> 67 --> 68 <logger name="*" minlevel="Debug" writeTo="logfile" /> 69 <logger name="*" minlevel="Info" writeTo="console" /> 70 71 <logger name="*" minlevel="Debug" writeTo="db" /> 72 </rules> 73 </nlog>
Web.Config要加上对应数据库连接
<?xml version="1.0" encoding="utf-8"?> <!-- 有关如何配置 ASP.NET 应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkId=169433 --> <configuration> <connectionStrings> <add name="NLogConn" connectionString="Server=.;uid=sa;pwd=sa;Database=db;"/> </connectionStrings> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> </configuration>
保存数据库结果：
写入oracle的配置，使用System.Data.OracleClient，.net 4.0以上已经抛弃
1 <targets> 2 <target name="oraclelog" type="Database"> 3 4 <dbProvider>System.Data.OracleClient.OracleConnection,System.Data.OracleClient, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</dbProvider> 5 6 <connectionString>Data Source=JMDB_215;User ID=TYUM_UM; Password=DEV_TYUM_UM;</connectionString> 7 8 <commandText>insert into RS_LOGTABLE (log_user,log_level,log_date,log_message) values(:log_user,:log_level,:log_date,:log_message)</commandText> 9 10 <parameter name=":log_user" layout="${aspnet-user-identity}"/> 11 <parameter name=":log_level" layout="${level}"/> 12 <parameter name=":log_date" layout="${date}"/> 13 <parameter name=":log_message" layout="${message}"/> 14 15 </target> 16 </targets> 17 <rules> 18 <logger name="*" minlevel="Debug" writeTo="oraclelog" /> 19 </rules>
写入oracle的配置，使用Oracle.DataAccess.Client，配置文件如下：
1 <targets> 2 <target name="oraclelog" type="Database"> 3 4 <!--<dbProvider>Oracle.ManagedDataAccess.Client,Oracle.ManagedDataAccess</dbProvider>--> 5 <dbProvider>Oracle.DataAccess.Client.OracleConnection,Oracle.DataAccess</dbProvider> 6 <connectionString>Data Source=orcl;User ID=oracle_user; Password=password;</connectionString> 7 8 <commandText>insert into RS_LOGTABLE (log_user,log_level,log_date,log_message) values(:log_user,:log_level,:log_date,:log_message)</commandText> 9 10 <parameter name=":log_user" layout="${machinename}"/> 11 <parameter name=":log_level" layout="${level}"/> 12 <parameter name=":log_date" layout="${date}"/> 13 <parameter name=":log_message" layout="${message}"/> 14 15 </target> 16 </targets> 17 18 <rules> 19 <logger name="oracleDbLog" minlevel="Debug" writeTo="oraclelog" /> 20 </rules>
C#调用代码：
Logger oracleLogger = LogManager.GetLogger("oracleDbLog"); oracleLogger.Error(new Exception("自定义异常oracle"), "错误信息 oracledb", string.Empty);
执行结果：
写入mysql，需应用MySql.Data程序集，安装Install-Package MySql.Data -Version 6.9.9，配置文件如下：
1 <targets> 2 <target name="MySQLLog" type="Database"> 3 <dbProvider>MySql.Data.MySqlClient.MySqlConnection,MySql.Data</dbProvider> 4 <connectionString>Server=192.168.0.2;Uid=root;Pwd=root;Database=mydb;</connectionString> 5 6 <commandText>insert into t_nlog (log_user,log_level,log_date,log_message) values(@log_user,@log_level,@log_date,@log_message)</commandText> 7 8 <parameter name="@log_user" layout="${machinename}"/> 9 <parameter name="@log_level" layout="${level}"/> 10 <parameter name="@log_date" layout="${date}"/> 11 <parameter name="@log_message" layout="${message}"/> 12 </target> 13 </targets> 14 15 <rules> 16 <logger name="*" minlevel="Debug" writeTo="MySQLLog" /> 17 </rules>
执行结果：
文件日志异常模板：
<target name="logfile" xsi:type="File" fileName="${basedir}/nlogs/${shortdate}.log" layout="${longdate}|${level}||${logger} ${message}| ${exception:format=tostring}" />
NLog日志写入到MongoDB，安装NLog.Mongo
PM> Install-Package NLog.Mongo
配置文件：1 <extensions> 2 <add assembly="NLog.Mongo"/> 3 </extensions> 4 5 <target xsi:type="Mongo" 6 name="mongoDefault" 7 connectionString="mongodb://192.168.0.226:6111/NLogging" 8 collectionName="DefaultLog" 9 cappedCollectionSize="26214400"> 10 <property name="ThreadID" layout="${threadid}" bsonType="Int32" /> 11 <property name="ThreadName" layout="${threadname}" /> 12 <property name="ProcessID" layout="${processid}" bsonType="Int32" /> 13 <property name="ProcessName" layout="${processname:fullName=true}" /> 14 <property name="UserName" layout="${windows-identity}" /> 15 </target> 16 17 <rules> 18 19 <logger name="*" level="Debug" writeTo="mongoDefault" /> 20 </rules>
执行结果如下：
