log4net保存到数据库系列五、新增数据库字段

2018-06-23 23:30:03来源：未知阅读 ()

园子里面有很多关于log4net保存到数据库的帖子,但是要动手操作还是比较不易，从头开始学习log4net数据库日志一、WebConfig中配置log4net

一、WebConfig中配置log4net
二、独立配置文件中配置log4net
三、代码中xml配置log4net
四、完整代码配置log4net
五、新增数据库字段

下面先一点一点来学习如果进行配置

1.下载，请参考log4net保存到数据库系列一：WebConfig中配置log4net

2.数据库脚本

CREATE TABLE [dbo].[Logs] (
    [ID]         INT            IDENTITY (1, 1) NOT NULL,
    [Level]      NVARCHAR (MAX) NULL,
    [Logger]     NVARCHAR (MAX) NULL,
    [Message]    NVARCHAR (MAX) NULL,
    [Date]       DATETIME       NOT NULL,
    [Exception]  NVARCHAR (MAX) NULL,
    [ModName]    NVARCHAR (MAX) NULL,
    [UserName]   NVARCHAR (MAX) NULL,
    [Mac]        NVARCHAR (MAX) NULL,
    [IP]         NVARCHAR (MAX) NULL,
    [Url]        NVARCHAR (MAX) NULL,
    [ActionName] NVARCHAR (MAX) NULL,
    [Name]       NVARCHAR (MAX) NULL
);

3.消息类

 public class JimMessage : IRequiresSessionState
    {
        public JimMessage()
        {
            IP = Util.getLocalIP();
            Mac = Util.getLocalMac();
            Url = System.Web.HttpContext.Current.Request.Url.AbsoluteUri;
        }
        public string IP { get; set; }
        public string Mac { get; set; }

        public string Url { get; set; }

        public string ModName { get; set; }    

        public string ActionName { get; set; }

        public string Message { get; set; }

        public string UserName { get; set; }

        public string Name { get; set; }
    }

4.自定义字段解析类

   public class MyLayout : PatternLayout
    {
        public MyLayout()
        {
            this.AddConverter("property", typeof(MyMessagePatternConverter));//指定自定义字段的解析类
        }
    }

public class MyMessagePatternConverter : PatternLayoutConverter//解析自定义属性，用反射获取属性名称
    {
        protected override void Convert(System.IO.TextWriter writer, log4net.Core.LoggingEvent loggingEvent)
        {
            if (Option != null)
            {
                WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
            }
            else
            {
                WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
            }
        }

        /// <summary>
        /// 通过反射获取传入的日志对象的某个属性的值
        /// </summary>
        /// <param name="property"></param>
        /// <returns></returns>
        private object LookupProperty(string property, log4net.Core.LoggingEvent loggingEvent)
        {
            object propertyValue = string.Empty;

            PropertyInfo propertyInfo = loggingEvent.MessageObject.GetType().GetProperty(property);
            if (propertyInfo != null)
                propertyValue = propertyInfo.GetValue(loggingEvent.MessageObject, null);

            return propertyValue;
        }
    }

5..测试代码

ILoggerRepository rep = LogManager.CreateRepository(Guid.NewGuid().ToString());

AdoNetAppender adoNetAppender = new AdoNetAppender();
adoNetAppender.BufferSize = -1;
adoNetAppender.ConnectionType = "System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089";

adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@log_date", DbType = System.Data.DbType.DateTime, Layout = new log4net.Layout.RawTimeStampLayout() });
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@log_level", DbType = System.Data.DbType.String, Size = 50, Layout = new Layout2RawLayoutAdapter(new PatternLayout("%level")) });

PatternLayout layout = new MyLayout() {ConversionPattern = "%property{UserName}"};
layout.ActivateOptions();  
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@UserName", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter( layout)});

layout.ActivateOptions();

layout = new MyLayout() { ConversionPattern = "%property{Mac}" };
layout.ActivateOptions();
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@Mac", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter(layout) });

layout = new MyLayout() { ConversionPattern = "%property{IP}" };
layout.ActivateOptions();
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@IP", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter(layout) });

layout = new MyLayout() { ConversionPattern = "%property{Url}" };
layout.ActivateOptions();
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@Url", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter(layout) });

layout = new MyLayout() { ConversionPattern = "%property{ActionName}" };
layout.ActivateOptions();
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@ActionName", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter(layout) });

layout = new MyLayout() { ConversionPattern = "%property{Name}" };
layout.ActivateOptions();
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@Name", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter(layout) });

layout = new MyLayout() { ConversionPattern = "%property{Message}" };
layout.ActivateOptions();
adoNetAppender.AddParameter(new AdoNetAppenderParameter { ParameterName = "@Message", DbType = System.Data.DbType.String, Size = 4000, Layout = new Layout2RawLayoutAdapter(layout) });

adoNetAppender.ActivateOptions();

BasicConfigurator.Configure(rep, adoNetAppender);

ILog log = LogManager.GetLogger(rep.Name, "NoBufferingTest");
JimMessage message = new JimMessage();
message.Message = "审核成功";
message.UserName = "金朝钱";
message.Url = Request.Url.ToString();
message.ModName = "其他入库";
message.ActionName = "审核";
message.Name = "Bill20150505";

log.Debug(message);
