log4net - 如何使用 log4net 在 Spring.NET 中配置日志记录？

Question

我想将 Spring.NET Aspect 库中的日志记录方面与 log4Net 一起使用。我发现this article如何将 log4Net 与通用日志记录 API 结合使用。

我的测试应用程序是控制台并基于 .NET 4.0 客户端配置文件。

第一次尝试

所以我在我的项目中引用了这些库:

• Spring.Core 版本 1.3.2.40943，运行时 v4.0.30319
• Spring.AOP 版本 1.3.2.40943，运行时 v4.0.30319
• Common.Logging 版本:1.2.0.0，运行时 v1.0.3705

上面的程序集来自 Program Files\Spring.NET 1.3.2\bin\net\4.0

• log4net版本:1.2.10.0，运行时v2.0.50727

我在 Program Files\Spring.NET 1.3.2\bin 中找不到程序集 Common.Logging.Log4Net.dll\net\4.0 所以我下载了这个程序集 from SourceForge :

• Common.Logging.Log4Net 版本 2.0.0.0 运行时 v2.0.50727

我在 app.config 中配置了记录器:

<?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>

并尝试了这个:

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

我遇到了这个运行时错误:

{"Could not configure Common.Logging from configuration section 'common/logging'."}

内部异常:

{"An error occurred creating the configuration section handler for common/logging: Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net' (E:\C# PROJECTS\STUDY\SPRING.NET\SpringNet.Aspects\LoggingWithLog4Net\bin\Debug\LoggingWithLog4Net.vshost.exe.Config line 18)"}

堆栈跟踪:

at Common.Logging.LogManager.BuildLoggerFactoryAdapter()

第二次尝试

我认为问题一定出在程序集 Common.Logging.Log4Net 版本 2.0.0.0 运行时 v2.0.50727 的版本中。因为我使用 Common.Logging 版本:1.2.0.0，运行时 v1.0.3705。

所以我将 Common.Logging 版本从 1.2.0.0 更改为 2.0.0.0。我使用 SourceForge 中的 Common.Logging .

并再次测试。我收到此错误:

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

内部异常:

{"Could not load file or assembly 'Common.Logging.Log4Net' or one of its dependencies. The system cannot find the file specified.":"Common.Logging.Log4Net"}

堆栈跟踪:

at System.RuntimeTypeHandle.GetTypeByName(String name, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMarkHandle stackMark, Boolean loadTypeFromPartialName, ObjectHandleOnStack type) at System.RuntimeTypeHandle.GetTypeByName(String name, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMark& stackMark, Boolean loadTypeFromPartialName) at System.RuntimeType.GetType(String typeName, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMark& stackMark) at System.Type.GetType(String typeName, Boolean throwOnError, Boolean ignoreCase) at Common.Logging.ConfigurationSectionHandler.ReadConfiguration(XmlNode section) in c:\CCNet\netcommon\trunk\modules\Common.Logging\src\Common\Common.Logging\Logging\ConfigurationSectionHandler.cs:line 130

第三次也是最后一次尝试

最后我在 spring 示例中找到了程序集 Common.Logging.Log4Net 版本 1.2.0.2，所以我使用了它。

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

测试并再次出现错误:

{"Could not configure Common.Logging from configuration section 'common/logging'."}

内部异常:

{"An error occurred creating the configuration section handler for common/logging: Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net' (E:\C# PROJECTS\STUDY\SPRING.NET\SpringNet.Aspects\LoggingWithLog4Net\bin\Debug\LoggingWithLog4Net.vshost.exe.Config line 18)"}

堆栈跟踪:

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

我真的很困惑我做错了什么？程序集版本有问题吗？

Answer 1

对于 Spring.NET 1.3.2，您应该使用:

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

确保最后两个 log4net dll 已复制到输出目录。由于您的代码不直接引用它，因此 Visual Studio 可能不会复制它们。
