使用ASP.NET MVC的log4net:没有任何反应

Question

我正在尝试将log4net与ASP.NET MVC一起使用,但我无法发生任何事情.我已经在我的web项目根目录中创建了一个配置:

<log4net>
    <root>
        <level value="INFO" />
        <appender-ref ref="RollingLogFileAppender"/>
    </root>

    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="C:\DWSApplicationFiles\AppLogs\app.log" />
        <appendToFile value="true" />
        <rollingStyle value="Size" />
        <maxSizeRollBackups value="10" />
        <maximumFileSize value="100KB" />
        <staticLogFileName value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" />
        </layout>
    </appender>

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="C:\DWSApplicationFiles\AppLogs\app.log" />
        <appendToFile value="false" />
        <datePattern value="-dddd" />
        <rollingStyle value="Date" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" />
        </layout>
    </appender>
</log4net>

在我被问到之前:是的,应用程序有权写入目录.我已对此进行了测试,该应用程序已获得此目录的权限.

这是我尝试使用log4net的地方:

public class HomeController : Controller
{
    readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
    public ActionResult Index()
    {
        log.Error("In Index  ");
         return View();
    }
}

当我运行应用程序并转到此控制器时,log4net什么都不做; 它不会在该目录或任何内容中创建文件.

我已经为log4net启用了内部调试,我在控制台中没有输出错误.以下是我在log4net上看到的全部内容:

log4net:log4net assembly [log4net,Version = 1.2.10.0,Culture = neutral,PublicKeyToken = 1b44e1d426115821].从[C:\ Users\twaldron.BULLFROGSPAS\AppData\Local\Temp\Temporary ASP.NET Files\root\7642c99a\60feb7f2\assembly\dl3\17247033\008dfd6d_e2d0ca01\log4net.DLL]加载.(Microsoft Windows NT 6.1.7600.0上的.NET运行时[2.0.50727.4952])

log4net:DefaultRepositorySelector:defaultRepositoryType [log4net.Repository.Hierarchy.Hierarchy]

log4net:DefaultRepositorySelector:为程序集创建存储库[Bullfrog.DWS.Web,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]

log4net:DefaultRepositorySelector:程序集[Bullfrog.DWS.Web,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]从[C:\ Users\twaldron.BULLFROGSPAS\AppData\Local\Temp\Temporary ASP.NET Files \根\ 7642c99a\60feb7f2 \组件\ DL3\2960c79f\b876bb2d_aca7cb01\Bullfrog.DWS.Web.DLL]

log4net:DefaultRepositorySelector:Assembly [Bullfrog.DWS.Web,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]没有指定RepositoryAttribute.

log4net:DefaultRepositorySelector:程序集[Bullfrog.DWS.Web,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]使用repository [log4net-default-repository]和存储库类型[log4net.Repository.Hierarchy.Hierarchy]

Answer 1

你在global.asax中有这样的东西吗？

void Application_Start(object sender, EventArgs e)
{
    string l4net = Server.MapPath("~/log4net.config");
    log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(l4net));

    ...

Answer 2

确保你打电话

log4net.Config.XmlConfigurator.Configure();

在您的应用程序启动时.

Answer 3

在ASP.NET MVC 4 Web应用程序中配置Log4Net

1. 下载Log4Net:

   • http://logging.apache.org/log4net/download.html

2. 在ASP.Net MVC 4应用程序中添加引用:

   1. Solution Explorer
   2. 右键单击项目名称
   3. 添加参考
   4. 浏览Log4Net.dll

3. 修改Web.config文件(源):

<configuration> 
    <configSections>
        <section
            name="log4net"
            type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
    <log4net>
        <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
            <param name="File" value="LOGS\log.txt"/>
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
            <appendToFile value="true" />
            <rollingStyle value="Size" />
            <maxSizeRollBackups value="2" />
            <maximumFileSize value="10MB" />
            <staticLogFileName value="true" />
            <layout type="log4net.Layout.PatternLayout">
                <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
            </layout>
        </appender>
        <root>
            <level value="ALL" />
            <appender-ref ref="LogFileAppender" />
        </root> 
        <logger name="test">
            <level value="DEBUG"></level>
        </logger>
    </log4net>
</configuration>

4. 修改AssemblyInfo.cs:

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

5. 修改global.asax.cs:

protected void Application_Start()
{
    log4net.Config.XmlConfigurator.Configure(new FileInfo(Server.MapPath("~/Web.config")));
}

6. 在要为其创建日志的类中添加记录器声明:

readonly log4net.ILog log =
    log4net.LogManager.GetLogger(
        System.Reflection.MethodBase.GetCurrentMethod().DeclaringType
    );

7. 使用日志功能:

log.Error("make mistakes");
