不使用动态创建的log4net托管Colored控制台
不使用动态创建的log4net托管Colored控制台
提问于 2021-12-17 19:45:54
我有一个程序，它有一个不同的模块集，称为基于输入参数。像订单，发货，定价等模块。我写了一个日志类，log4net是基础，尽管也需要一些定制的日志记录。我想要的是让每个模块都有自己的日志文件，到目前为止，我能够让log4net为每个文件动态创建附加程序。
我还能够获得控制台显示的时间，当它可能是手动运行，但我失去了(并且不知道如何使它工作是彩色控制台附录。我找到了用于创建追加器的基本解决方案这里，然后我使用此链接来研究如何创建控制台和ManagedColoredConsole追加程序，但是当它仍然写入控制台时，我没有得到颜色。
有东西不见了，但我不知道是什么。我编写了一个小测试程序来尝试解决这个问题，这就是日志类：
using log4net;
using log4net.Appender;
using log4net.Layout;
using log4net.Repository.Hierarchy;
using System;
using System.Linq;
namespace TestLogging
{
public class Logging
{
// Since the current version of logging will require more custom fields passed into the logging table
// I'm going to set up a wrapper around the log for net processing. This should simplify the way we call it in
// the main program sections so we don't have to keep adding constants like pid and we can deal with variables
// like item, order number, shipping numbers
public static ILog log = null;
public string transType = "";
public string pid = "0";
private string logModule = "main";
private string path = "";
public Logging(string LogModule)
{
logModule = LogModule; // set up to default to main then pass in the specific log file name for log4net
SetLevel("Log4net.MainForm", "ALL");
path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
string execPath = AppDomain.CurrentDomain.BaseDirectory;
if (log.Logger.Repository.GetAppenders().Count() == 0)
{
//CreateConsoleAppender();
CreateManagedColorConsoleAppender();
}
AddAppender(LogModule, CreateFileAppender(logModule, execPath + "\\logs\\" + logModule + ".log"));
}
public void Info(string message, string sohnum = null, string itmref = null, string sdhnum = null, double processtime = 0.0)
{
setCustom(sohnum, itmref, sdhnum, processtime);
log.Info(message);
}
private void setCustom(string sohnum = null, string itmref = null, string sdhnum = null, double processtime = 0.0)
{
log4net.ThreadContext.Properties["TransType"] = transType;
log4net.ThreadContext.Properties["sohnum_0"] = sohnum;
log4net.ThreadContext.Properties["itmref_0"] = itmref;
log4net.ThreadContext.Properties["sdhnum_0"] = sdhnum;
log4net.ThreadContext.Properties["processtime"] = processtime.ToString();
log4net.ThreadContext.Properties["pid"] = pid;
}
// Set the level for a named logger
public static void SetLevel(string loggerName, string levelName)
{
log = LogManager.GetLogger(loggerName);
Logger l = (Logger)log.Logger;
l.Level = l.Hierarchy.LevelMap[levelName];
}
// Add an appender to a logger
public static void AddAppender(string loggerName, IAppender appender)
{
log = LogManager.GetLogger(loggerName);
Logger l = (Logger)log.Logger;
l.Repository.Configured = true;
l.AddAppender(appender);
}
// Create a new file appender
public static IAppender CreateFileAppender(string name, string fileName)
{
FileAppender appender = new
FileAppender();
appender.Name = name;
appender.File = fileName;
appender.AppendToFile = true;
PatternLayout layout = new PatternLayout();
layout.ConversionPattern = "%d [%t] %-5p %c [%x] - %m%n";
layout.ActivateOptions();
appender.Layout = layout;
appender.ActivateOptions();
return appender;
}
public static IAppender CreateConsoleAppender()
{
ConsoleAppender appender = new ConsoleAppender();
appender.Name = "console";
PatternLayout layout = new PatternLayout();
layout.ConversionPattern = "%d [%t] %-5p %c [%x] - %m%n";
layout.ActivateOptions();
appender.Layout = layout;
appender.ActivateOptions();
var hierarchy = (Hierarchy)LogManager.GetRepository();
hierarchy.Configured = true;
hierarchy.Root.AddAppender(appender);
return appender;
}
public static IAppender CreateManagedColorConsoleAppender()
{
ManagedColoredConsoleAppender appender = new ManagedColoredConsoleAppender();
ManagedColoredConsoleAppender.LevelColors mapping = new ManagedColoredConsoleAppender.LevelColors();
appender.Name = "ManagedColoredConsoleAppender";
mapping.Level = log4net.Core.Level.Debug;
mapping.ForeColor = ConsoleColor.Blue;
appender.AddMapping(mapping);
mapping.Level = log4net.Core.Level.Info;
mapping.ForeColor = ConsoleColor.Green;
appender.AddMapping(mapping);
mapping.Level = log4net.Core.Level.Error;
mapping.ForeColor = ConsoleColor.Yellow;
appender.AddMapping(mapping);
mapping.Level = log4net.Core.Level.Fatal;
mapping.ForeColor = ConsoleColor.Red;
appender.AddMapping(mapping);
PatternLayout layout = new PatternLayout();
layout.ConversionPattern = "%d [%t] %-5p %c [%x] - %m%n";
layout.ActivateOptions();
appender.Layout = layout;
appender.ActivateOptions();
var hierarchy = (Hierarchy)LogManager.GetRepository();
hierarchy.Root.AddAppender(appender);
hierarchy.Configured = true;
hierarchy.Root.Level = log4net.Core.Level.Info;
return appender;
}
}
}它是粗糙的，但这只是为了测试和学习。
这是主要节目：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace TestLogging
{
public class Program
{
//private Logging logging = new Logging("file");
private static Logging logit = new Logging("main");
static void Main(string[] args)
{
logit.Info("This is the main program");
ordersClass orders = new ordersClass();
orders.callMe();
shipments shipit = new shipments();
shipit.shipMe();
}
}
}以及写入不同日志文件的类之一：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace TestLogging
{
public class ordersClass
{
private Logging logit = new Logging("orders");
public void callMe()
{
logit.Info("Just placed an order");
}
}
}当我设置一个断点来查看日志对象时，我可以看到托管颜色作为根附录存在，而其他在第一次创建时添加的颜色。关于以编程方式使用log4net并没有太多的信息，但我希望有人能做到这一点。

当我更多地阅读时，我发现了如何打开log4net的内部日志记录。把它放在app.config文件中，是的，这很有帮助，因为它向我展示了如何解决我的问题，尽管它不能动态地工作仍然暗示着我。
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>我发现了几件事：
如果您是以编程方式设置的话，Log4net不需要配置文件来工作。因为我没有将“复制到输出目录”设置为“不要复制”，所以没有将配置文件放在exe文件夹中。这显示了您不需要配置文件来进行日志记录，但它仍然没有回答为什么没有颜色。
如果您决定使用一个配置文件，但不要放入根中引用的附录，log4net会记录错误，但仍然工作。我有这个
<appender-ref ref="ManagedColoredConsoleAppender" />但文件里没有附录。我添加了ManagedColorConsole附录，现在我获得了彩色控制台消息和登录到多个文件。这是一个解决方案，但没有解释为什么我可以动态添加颜色附录，但不能让它工作。如果有答案，请发邮件。同时，这是一个已解决的问题。
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="ManagedColoredConsoleAppender" />
</root>
<appender name="ManagedColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
<mapping>
<level value="INFO" />
<foreColor value="Green, HighIntensity" />
</mapping>
<mapping>
<level value="DEBUG" />
<foreColor value="Green" />
</mapping>
<mapping>
<level value="ERROR" />
<foreColor value="Yellow, HighIntensity" />
</mapping>
<mapping>
<level value="FATAL" />
<foreColor value="Red, HighIntensity" />
</mapping>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
