[好用工具]log4net配置說明(MS SQL)

Log4Net是apache推出來的，它支援多種程式語言的log，如官方網站所示：

PHP、.NET、java、C++..

每種語言的配置及相關文件，官網有詳細介紹　Apache logging Services　可參考
以下提供我實際配置log4n + MS Sql成功的設定：

步驟一：

AssemblyInfo.cs載入組件設定

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

步驟二：

新增資料表至MS SQL

CREATE TABLE [dbo].[Log] (
    [Id] [int] IDENTITY (1, 1) NOT NULL,
    [Date] [datetime] NOT NULL,
    [Thread] [varchar] (255) NOT NULL,
    [Level] [varchar] (50) NOT NULL,
    [Logger] [varchar] (255) NOT NULL,
    [Message] [varchar] (4000) NOT NULL,
    [Exception] [varchar] (2000) NULL
)

步驟三：設定log4n.config

configSections

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />

<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
    <bufferSize value="100" />
    <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <connectionString value="data source=[資料庫連線];initial catalog=[資料庫名稱];integrated security=false;persist security info=True;User ID=[使用者];Password=[密碼]" />
    <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
    <parameter>
        <parameterName value="@log_date" />
        <dbType value="DateTime" />
        <layout type="log4net.Layout.RawTimeStampLayout" />
    </parameter>
    <parameter>
        <parameterName value="@thread" />
        <dbType value="String" />
        <size value="255" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%thread" />
        </layout>
    </parameter>
    <parameter>
        <parameterName value="@log_level" />
        <dbType value="String" />
        <size value="50" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%level" />
        </layout>
    </parameter>
    <parameter>
        <parameterName value="@logger" />
        <dbType value="String" />
        <size value="255" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%logger" />
        </layout>
    </parameter>
    <parameter>
        <parameterName value="@message" />
        <dbType value="String" />
        <size value="4000" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%message" />
        </layout>
    </parameter>
    <parameter>
        <parameterName value="@exception" />
        <dbType value="String" />
        <size value="2000" />
        <layout type="log4net.Layout.ExceptionLayout" />
    </parameter>
</appender>

<root>
   <level value="All" />

　　←分為七級，可自行設定OFF、FATAL、ERROR、WARN、INFO、DEBUG、ALL

   ←這邊設定所有等級的log都要寫入資料庫做記錄
   <appender-ref ref="AdoNetAppender" />
</root>

步驟四：Test.aspx

 private static readonly log4net.ILog log = log4net.LogManager.GetLogger(typeof(WebForm1));
 protected void Page_Load(object sender, EventArgs e){
 log.Info("^_^");
}

步驟五：看資料庫有沒有成功寫入資料

步驟六：成功^_^
