How to configure logging in Spring.NET using log4net?

I would like to use the Spring.NET Aspect Library Logging aspect along with log4Net. I found this article how to use log4Net with the Common Logging API.

My test application is console based and based on the .NET 4.0 client profile.

1st attempt

Therefore, I refer to these libraries in my project:

  • Spring Version for version 1.3.2.40943, runtime v4.0.30319
  • Spring.AOP version 1.3.2.40943, runtime v4.0.30319
  • Common.Logging version: 1.2.0.0, runtime v1.0.3705

Assemblies are higher than the program files \ Spring.NET 1.3.2 \ bin \ net \ 4.0

  • log4net version: 1.2.10.0, runtime v2.0.50727

I could not find the assembly Common.Logging.Log4Net.dll in Program Files \ Spring.NET 1.3.2 \ bin \ net \ 4.0, so I download this assembly from SourceForge :

  • Common.Logging.Log4Net version 2.0.0.0 runtime v2.0.50727

I configured logger in app.config:

<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="spring"> <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/> <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core"/> </sectionGroup> <sectionGroup name="common"> <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" /> </sectionGroup> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <common> <logging> <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net"> <arg key="configType" value="INLINE" /> </factoryAdapter> </logging> </common> <log4net> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger %ndc - %message%newline" /> </layout> </appender> <root> <level value="DEBUG" /> <appender-ref ref="ConsoleAppender" /> </root> <logger name="myLogger"> <level value="DEBUG" /> </logger> </log4net> <spring> <context> <resource uri="config://spring/objects"/> </context> <objects xmlns="http://www.springframework.net"> </objects> </spring> </configuration>

and tried this:

 ILog log = LogManager.GetLogger("myLogger"); log.Error("hello world");

I got this runtime error:

{"Failed to configure Common.Logging from the 'General / Logging' configuration section." }

Internal exception:

{"An error occurred while creating the configuration section handler for common / logging: cannot create type" Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net '(E: \ C # PROJECTS \ RESEARCH \ Spring.NET \ SpringNet.Aspects \ LoggingWithLog4Net \ Bin \ Debug \ LoggingWithLog4Net.vshost.exe.Config line 18) "}

Stacktrace:

in Common.Logging.LogManager.BuildLoggerFactoryAdapter ()

Second attempt

I think the problem should be in the build version of the Common.Logging.Log4Net version 2.0.0.0 runtime v2.0.50727. Because I used Common.Logging version: 1.2.0.0, runtime v1.0.3705.

So, I changed the version of Common.Logging from 1.2.0.0 to 2.0.0.0. I used Common.Logging from SourceForge .

And checked again. I got this error:

Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net

Internal exception:

{"Failed to load the file or assembly" Common.Logging.Log4Net "or one of its dependencies. The system cannot find the file indicated.": "Common.Logging.Log4Net"}

Stacktrace:

Third and final attempt

Finally, I found the Common.Logging.Log4Net assembly version 1.2.0.2 in spring examples, so I used it.

  • Common.Logging.Log4Net version 1.2.0.2
  • Common.Logging version 1.2.0.0
  • log4Net 1.2.10.0

Tested and error appeared again:

{"Failed to configure Common.Logging from the 'General / Logging' configuration section." }

Internal exception:

{"An error occurred while creating the configuration section handler for common / logging: cannot create type" Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net '(E: \ C # PROJECTS \ RESEARCH \ Spring.NET \ SpringNet.Aspects \ LoggingWithLog4Net \ Bin \ Debug \ LoggingWithLog4Net.vshost.exe.Config line 18) "}

Stacktrace:

{"Unable to create type" Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net '"}

Am I really confusing what I'm doing badly? Some problem with the build version?

For Spring.NET 1.3.2 you should use:

  • Common.Logging 2.0.0
  • Common.Logging.Log4Net 2.0.0
  • log4net 1.2.10

Make sure the last two log4net copied to the output directory. Since your code does not reference it directly, they cannot be copied using Visual Studio.

Also, instead of

 <resource uri="config://springs/objects"/>

Try

 <resource uri="config://spring/objects"/>

In your configuration file, the name of the section is "spring", not "spring". I copied your work to do my work and got into the same problem. Finally figured out why.

Hope this helps!

Another possibility:

  • Common.Logging 2.1.1
  • Common.Logging.Log4Net 2.1.1
  • log4net 1.2.10

I recommend skipping Common.Logging 2.1.0 since it threw this exception when reading the perfectly valid app.config section:

"Cannot overlay an object of type" System.Configuration.DefaultSection "onto type" System.Configuration.AppSettingsSection ".

Installation 2.1.1 fixes the problem.
