Log4net使用（二）

Log4net同时按照日期和大小生成RollingFile和访问Sybase数据库配置

1. Log4net同时按照日期和大小生成RollingFile

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> 
<file value="test.log" /> 
<appendToFile value="true" /> 

<rollingStyle value="Composite" /> 
<datePattern value=".yyyy_MM_dd" /> 
<maxSizeRollBackups value="10" /> 
<maximumFileSize value="10000" /> 
<staticLogFileName value="false" /> 
<layout type="log4net.Layout.PatternLayout"> 
<header value="[Header]
 " /> 
<footer value="[Footer]
 " /> 
<conversionPattern value="%date %type %file %line %method %location %class %C %F %L %l %M" /> 
</layout> 
</appender>

这样生成的日志类似test.log.2006_06_09,test.log.2006_06_08，如果哪一天的日志超过10000，那么日志名为test.log.2006_06_10.1、test.log.2006_06_10.2 .......

2.访问Sybase数据库配置

<appender name="ADONetAppender_Sybase1" type="log4net.Appender.AdoNetAppender"> 
<bufferSize value="1" /> 
<connectionType value="System.Data.Odbc.OdbcConnection, System.Data, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> 
<connectionString value="Driver={SYBASE SYSTEM 11};Srvr=basil;Uid=sa;Pwd=;DB=AddressBook" /> 
<commandText value="Log_add ? ,? , ?, ?, ?" /> 
<commandType value="StoredProcedure" /> 

<parameter> 
<parameterName value="@log_date" /> 
<dbType value="DateTime" /> 

<layout type="log4net.Layout.PatternLayout"> 
<conversionPattern value="%date{yyyy-MM-dd hh:mm:ss}" /> 
</layout> 

</parameter> 

<parameter> 
<parameterName value="@thread" /> 
<dbType value="String" /> 
<size value="255" /> 
<layout type="log4net.Layout.PatternLayout"> 
<conversionPattern value="%thread -just for test" /> 
</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="255" /> 
<layout type="log4net.Layout.PatternLayout"> 
<conversionPattern value="%message" /> 
</layout> 
</parameter> 
</appender>
