log4net日志管理

    1、添加log4net引用



    2、在项目里添加log4net.config文件



    3、log4net.config代码如下，可修改添加字段
    需要注意的是，如果有新增字段，需要自己转换，添加一个自定义的Layout，修改方式：

    <layout type="ITCGB.Intel._10th.Web.Common.Logger.CustomLayout">，这里我添加一个CustomLayout，type需要赋值为CustomLayout的路径。
    数据库链接字符串需要自己去配置：将数据库的地址、名称、账号、密码替换为你对应的数据库即可
    <connectionString value="data source={数据库地址};initial catalog={数据库名称};Integrated Security=false;user id={数据库账号};password={数据库密码};" />

    <?xml version="1.0"?>
<configuration>
  <!--声明一个名为“log4net”的自定义配置节-->
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
  </configSections>

  <!--log4net配置信息-->

    <logger name="ErrorLogger">
      <level value="Erros"/>
      <!--定义在这个级别之上的日志才会被记录-->
      <appender-ref ref="ErrorAppender" />
      <!--定义日志对象使用的Appender对象-->
    </logger>

    <!--Appenders用来定义日志的输出方式 -->

    </appender>

    <!--<root>
      <level value="DEBUG"/>
      <appender-ref ref="InfoAppender"/>
    </root>-->
  </log4net>

  <startup>
    <supportedRuntime version="v4.7.2" sku=".NETFramework,Version=v4.7.2"/>
  </startup>
</configuration>

    4、创建CustomLayout类


     public class CustomLayout : log4net.Layout.PatternLayout
    {
        public CustomLayout()
        {
            this.AddConverter("IP", typeof(IPPatternConverter));
            this.AddConverter("ControllerName", typeof(ControllerNamePatternConverter));
            this.AddConverter("ActionName", typeof(ActionNamePatternConverter));
            this.AddConverter("Description", typeof(DescriptionPatternConverter));
            this.AddConverter("Url", typeof(UrlPatternConverter));
            this.AddConverter("UserId", typeof(UserIdPatternConverter));
            this.AddConverter("UserBrowser", typeof(UserBrowserPatternConverter));
            this.AddConverter("UserBrowserVersion", typeof(UserBrowserVersionPatternConverter));
        }
    }

    internal sealed class IPPatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.IP);
        }
    }

    internal sealed class DescriptionPatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.Description);
        }
    }

    internal sealed class ControllerNamePatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.ControllerName);
        }
    }

    internal sealed class ActionNamePatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.ActionName);
        }
    }

    internal sealed class UrlPatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.Url);
        }
    }

    internal sealed class UserBrowserPatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.UserBrowser);
        }
    }

    internal sealed class UserIdPatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.UserId);
        }
    }

    internal sealed class UserBrowserVersionPatternConverter : PatternLayoutConverter
    {
        override protected void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            LogModel logMessage = loggingEvent.MessageObject as LogModel;

            if (logMessage != null)
                writer.Write(logMessage.UserBrowserVersion);
        }
    }

    5、创建LogModel类，需要的字段

    public class LogModel
    {
        public string IP { get; set; }
        public string ControllerName { get; set; }
        public string ActionName { get; set; }
        public string Description { get; set; }
        public string Url { get; set; }
        public int UserId { get; set; }
        public string UserBrowser { get; set; }
        public string UserBrowserVersion { get; set; }
    }

    6、创建LoggerHelper类


    //这里需要配置log4net.config的所在的位置
 [assembly: XmlConfigurator(ConfigFile = "Configs/log4net.config", Watch = true)]
namespace ITCGB.Intel._10th.Web.Common.Logger
{
    public class LogHelper
    {
        private static readonly ILog loginfo = LogManager.GetLogger("InfoLogger");

        private static readonly ILog logerror = LogManager.GetLogger("ErrorLogger");

        /// <summary>
        /// 记录一般日志
        /// </summary>
        public static void LogInfo(LogModel opLog)
        {
            try
            {
                if (loginfo.IsInfoEnabled)
                {
                    loginfo.Info(opLog);
                }
            }
            catch (Exception ex)
            {
                throw;
            }
            
        }

        /// <summary>
        /// 记录错误
        /// </summary>
        public static void LogError(LogModel opLog, Exception ex)
        {
            if (logerror.IsErrorEnabled)
            {
                logerror.Error(opLog, ex);
            }
        }

        /// <summary>
        /// 记录严重错误
        /// </summary>
        public static void LogFatal(LogModel opLog, Exception ex)
        {
            if (logerror.IsFatalEnabled)
            {
                logerror.Fatal(opLog, ex);
            }
        }

        /// <summary>
        /// 记录警告
        /// </summary>
        public static void LogWarn(LogModel opLog)
        {
            if (logerror.IsWarnEnabled)
            {
                logerror.Warn(opLog);
            }
        }
    }
}

    7、添加LogInfo的过滤器和异常过滤器


    LogInfoAttribute 过滤器

    /// <summary>
    /// 日志过滤
    /// </summary>
    public class LogInfoAttribute : ActionFilterAttribute
    {
        /// <summary>
        /// 描述
        /// </summary>
        private string _description;

        /// <summary>
        /// 日志记录过滤
        /// </summary>
        /// <param name="title">日志标题</param>
        /// <param name="content">日志描述</param>
        public LogInfoAttribute(
            string description)
        {
            _description = description;
        }


        public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
