如何使用log4net配置Spring.NET中的日志记录？

Question

我想从Spring.NET Aspect库使用Logging方面和log4Net.我发现这篇文章如何将log4Net与Common Logging API一起使用.

我的测试应用程序是控制台,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这些库:

• Spring.Core版本1.3.2.40943,运行时版本v4.0.30319
• Spring.AOP版本1.3.2.40943,运行时版本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,运行时版本2.00.50727

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

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

我在app.config中配置了logger:

<?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>

并试过这个:

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

我收到了这个运行时错误:

{"无法从配置部分'common/logging'配置Common.Logging."}

内部异常:

{"创建公共/日志记录的配置节处理程序时出错:无法创建类型'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:

)

第二次尝试

我认为问题必须是程序集Common.Logging.Log4Net 版本2.0.0.0运行时v2.0.50727的版本.因为我使用了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.我使用了SourceForge的 Common.Logging .

并再次测试.我收到了这个错误:

无法创建类型'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter,Common.Logging.Log4Net'

内部异常:

{"无法加载文件或程序集'Common.Logging.Log4Net'或其中一个依赖项.系统找不到指定的文件.":"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,布局loadTypeFromPartialName)在System.RuntimeType.GetType(String typeName,Boolean throwOnError,Boolean ignoreCase,Boolean reflectionOnly,StackCrawlMark&stackMark)处于System.Type.GetType(String typeName,Boolean throwOnError,Boolean ignoreCase)at Common.Logging.ConfigurationSectionHandler.ReadConfiguration( XmlNode部分)在c:\ CCNet \netcommon\trunk\modules\Common.Logging\src\Common\Common.Logging\Logging\ConfigurationSectionHandler.cs:第130行

第三次和最后一次尝试

最后我在spring例子中找到了汇编Common.Logging.Log4Net 1.2.0.2版,所以我用它.

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

测试并再次出错:

{"无法从配置部分'common/logging'配置Common.Logging."}

内部异常:

{"创建公共/日志记录的配置节处理程序时出错:无法创建类型'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:

{"无法创建类型'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter,Common.Logging.Log4Net'"}

我真的很困惑我做的不好吗？程序集版本有些问题？

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

确保将最后两个log4netdll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.
