二、NLog集成步骤

  1. 下载模板项目,下载地址:https://aspnetboilerplate.com/Templates
    选择.Net Core项目
  2. 新建一个.NET
    Standard类库项目Abp.Castle.NLog
    ca88手机版 1
  3. 添加NuGet包Castle.Core,
    Castle.LoggingFacility, NLog
    ca88手机版 2
  4. 参考abp log4net(ABP源码)添加class NLogLogger继承MarshalByRefObject并实现接口Castle.Core.Logging.ILogger

      1 using System;
      2 using System.Globalization;
      3 using ILogger = Castle.Core.Logging.ILogger;
      4 using NLogCore = NLog;
      5 
      6 namespace Abp.Castle.Logging.NLog
      7 {
      8     [Serializable]
      9     public class NLogLogger :
     10         MarshalByRefObject,
     11         ILogger
     12     {
     13         protected internal NLogCore.ILogger Logger { get; set; }
     14         //protected internal NLogLoggerFactory Factory { get; set; }
     15 
     16         public NLogLogger(NLogCore.ILogger logger)
     17         {
     18             Logger = logger;
     19         }
     20 
     21         internal NLogLogger()
     22         {
     23         }
     24 
     25         public bool IsDebugEnabled => Logger.IsEnabled(NLogCore.LogLevel.Debug);
     26

     30 
     31         public bool IsInfoEnabled => Logger.IsEnabled(NLogCore.LogLevel.Info);
     32

     34 
     35         public ILogger CreateChildLogger(string loggerName)
     36         {

     38         }
     39 
     40         public void Debug(string message)

    150         public void Info(Func<string> messageFactory)
    151         {
    152             Logger.Info(messageFactory);
    153         }
    154 
    155         public void Info(string message, Exception exception)
    156         {
    157             Logger.Info(exception, message);
    158         }
    159 
    160         public void InfoFormat(string format, params object[] args)
    161         {
    162             Logger.Info(CultureInfo.InvariantCulture, format, args);
    163         }
    164 
    165         public void InfoFormat(Exception exception, string format, params object[] args)
    166         {
    167             Logger.Info(exception, CultureInfo.InvariantCulture, format, args);
    168         }
    169 
    170         public void InfoFormat(IFormatProvider formatProvider, string format, params object[] args)
    171         {
    172             Logger.Info(formatProvider, format, args);
    173         }
    174 
    175         public void InfoFormat(Exception exception, IFormatProvider formatProvider, string format, params object[] args)
    176         {

    189 
    190         public void Warn(string message, Exception exception)
    191         {
    192             Logger.Warn(exception, message);
    193         }
    194 
    195         public void WarnFormat(string format, params object[] args)

    198         }
    199 
    200         public void WarnFormat(Exception exception, string format, params object[] args)
    201         {
    202             Logger.Warn(exception, CultureInfo.InvariantCulture, format, args);
    203         }
    204 
    205         public void WarnFormat(IFormatProvider formatProvider, string format, params object[] args)
    206         {
    207             Logger.Warn(formatProvider, format, args);
    208         }
    209 
    210         public void WarnFormat(Exception exception, IFormatProvider formatProvider, string format, params object[] args)
    211         {
    212             Logger.Warn(exception, formatProvider, format, args);
    213         }
    214     }
    215 }
    
  5. 添加工厂类NLogLoggerFactory并实现抽象类Castle.Core.Logging.AbstractLoggerFactory

     1 using Castle.Core.Logging;
     2 using System;
     3 using System.IO;
     4 using NLogCore = NLog;
     5 
     6 namespace Abp.Castle.Logging.NLog
     7 {
     8 
     9     public class NLogLoggerFactory : AbstractLoggerFactory
    10     {
    11         internal const string DefaultConfigFileName = "nlog.config";
    12         //private readonly ILoggerRepository _loggerRepository;
    13 
    14         public NLogLoggerFactory()
    15        : this(DefaultConfigFileName)
    16         {
    17 
    18         }
    19 
    20         public NLogLoggerFactory(string configFileName)
    21         {
    22             if (!File.Exists(configFileName))
    23             {
    24                 throw new FileNotFoundException(configFileName);
    25             }
    26             NLogCore.LogManager.Configuration = new NLogCore.Config.XmlLoggingConfiguration(configFileName);
    27         }
    28 
    29         public override ILogger Create(string name)
    30         {
    31             if (name == null)
    32             {
    33                 throw new ArgumentNullException(nameof(name));
    34             }
    35             return new NLogLogger(NLogCore.LogManager.GetLogger(name));
    36         }
    37 
    38         public override ILogger Create(string name, LoggerLevel level)
    39         {
    40             throw new NotSupportedException("Logger levels cannot be set at runtime. Please review your configuration file.");
    41         }
    42     }
    43 }
    
  6. 添加LoggingFacility的扩展方法UseAbpNLog

     1 using Castle.Facilities.Logging;
     2 
     3 namespace Abp.Castle.Logging.NLog
     4 {
     5     public static class LoggingFacilityExtensions
     6     {
     7         public static LoggingFacility UseAbpNLog(this LoggingFacility loggingFacility)
     8         {
     9             return loggingFacility.LogUsing<NLogLoggerFactory>();
    10         }
    11     }
    12 }
    
  7. 移除Abp.Castle.Log4Net包,添加Abp.Castle.NLog到Host项目
    ca88手机版 3

  8. 添加配置文件nlog.config

     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       autoReload="true"
     5       internalLogLevel="Warn"
     6       internalLogFile="App_Data\Logs\nlogs.txt">
     7 
     8   <variable name="logDirectory" value="${basedir}\log\"/>
     9 
    10   <!--define various log targets-->
    11   <targets>
    12 
    13     <!--write logs to file-->
    14     <target xsi:type="File" name="allfile" fileName="${logDirectory}\nlog-all-${shortdate}.log"
    15                  layout="${longdate}|${logger}|${uppercase:${level}}|${message} ${exception}" />
    16 
    17     <target xsi:type="File" name="ownFile-web" fileName="nlog-my-${shortdate}.log"
    18                  layout="${longdate}|${logger}|${uppercase:${level}}|${message} ${exception}" />
    19 
    20     <target xsi:type="Null" name="blackhole" />
    21 
    22   </targets>
    23 
    24   <rules>
    25     <!--All logs, including from Microsoft-->
    26     <logger name="*" minlevel="Trace" writeTo="allfile" />
    27 
    28     <!--Skip Microsoft logs and so log only own logs-->
    29     <logger name="Microsoft.*" minlevel="Trace" writeTo="blackhole" final="true" />
    30     <logger name="*" minlevel="Trace" writeTo="ownFile-web" />
    31   </rules>
    32 </nlog>
    
  9. 修改Startup,
    将原来的日志组件log4net替换为nlog

    注释using
    Abp.Castle.Logging.Log4Net; 添加using Abp.Castle.Logging.NLog;

    1 //using Abp.Castle.Logging.Log4Net;
    2 using Abp.Castle.Logging.NLog;
    

    修改ConfigureServices方法

     1  // Configure Abp and Dependency Injection
     2  return services.AddAbp<AbpBasicWebHostModule>(
     3      // Configure Log4Net logging
     4      //options => options.IocManager.IocContainer.AddFacility<LoggingFacility>(
     5      //    f => f.UseAbpLog4Net().WithConfig("log4net.config")
     6      //)
     7 
     8      // Configure Nlog Logging
     9       options => options.IocManager.IocContainer.AddFacility<LoggingFacility>(
    10       f => f.UseAbpNLog().WithConfig("nlog.config")
    11       )
    12   );
    
  10. 测试

     1 public IActionResult Index()
     2 {
     3       //nlog test
     4        Logger.Info("信息日志");
     5        Logger.Debug("调试日志");
     6        Logger.Error("错误日志");
     7        Logger.Fatal("异常日志");
     8        Logger.Warn("警告日志");
     9        return Redirect("/swagger");
    10 }
