IIS中托管的WCF服务库的log4net [英] log4net for WCF Service library hosted in IIS

问题描述

对于一个项目，我有一个WCF服务库（目前非常简单）
，它通过WCF服务网站项目在IIS 7.5中托管。

For a project I have a WCF Service library (very simple at the moment) which is hosted in IIS 7.5 via a WCF Service Website project.

对于该WCF服务库，我需要log4net来记录一些重大事件。

For that WCF Service library I need log4net to log some major events.

但是在启动和访问网站后，没有创建日志文件。

But after starting and accessing the website, no logfile is created.

以下是我的配置详情：

WCF服务库：

App.config (is containing the following)

<appSettings>
    <add key="log4net-config-file" value="log4net.config"/>
    <!-- <add key="log4net.Internal.Debug" value="true"/> -->
</appSettings>

log4net.config

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="System.Configuration.IgnoreSectionHandler"/>
  </configSections>
  <log4net>
    <root>
      <level value="DEBUG"/>
      <appender-ref ref="RollingLogFileAppender"/>
    </root>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="C:\\Temp\\Logfile.txt"/>
      <appendToFile value="true"/>
      <rollingStyle value="Size"/>
      <datePattern value="yyyyMMdd"/>
      <maxSizeRollBackups value="5"/>
      <maximumFileSize value="100KB"/>
      <staticLogFileName value="true"/>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%d [%t] %-5p %c - %m%n"/>
      </layout>
    </appender>
  </log4net>
</configuration>

In AssemblyInfo.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

On top of the Service class
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

In the Static Constructor (mainly due to fiddling around)
string configFile = ConfigurationManager.AppSettings["log4net-config-file"];
XmlConfigurator.Configure(new FileInfo(configFile));
logger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

In the non-static constructor:
logger.Info("Hello world!");

Wcf服务网站项目：

 Web.Config is basically the same as App.Config of service library

 <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true"/>

到目前为止我尝试了什么：

• 更改对IUSR（服务正在运行的那个）的C：\ Temp \的访问权限
  来写（和修改）


• 重新启动机器



• 阅读有关
  主题的大量文章和SO问题，例如为iis托管log4net wcf服务和快速而脏的log4net for webapplications指南

激活log4net内部日志记录（通常在DebugView中看到）

activated log4net internal logging (which is normally seen in DebugView)

DebugView中没有输出，IIS配置日志中没有关于log4net的信息。

There is no output in DebugView and nothing about log4net in the IIS configured logs.

我怎样才能找出问题所在？

推荐答案

问题是：

在IIS中托管时，在IIS的当前目录中搜索了log4net配置文件，这在我的情况下是：

When hosted in IIS, the log4net config file was searched in the current directory of IIS, which is in my case:

C:\Windows\System32\inetsrv

但配置文件保存在WCF服务的物理路径中。

But the config file is saved in the physical path of the WCF service.

所以我在 Web.config

<appSettings>
    <add key="log4net_config" value="log4net.config" />
</appSettings>

在服务类的构造函数中，我调用

And in the Constructor of the Service-class I call

var fullPath = ConfigurationManager.AppSettings["log4net_config"];

var physicalPath = System.Web.Hosting.HostingEnvironment.MapPath("/");

// to keep it compatible with self hosting 
if (physicalPath != null)
{
    fullPath = Path.Combine(physicalPath, fullPath);
}

var fileInfo = new FileInfo(configFile);

XmlConfigurator.ConfigureAndWatch(fileInfo);
