IBatis.Net中提供了方便的日志處理，可以輸出sql語句等調試信息。
常用的有兩種：
1、輸出到控制臺：

??<configSections>????<sectionGroup?name="iBATIS">??????<section?name="logging"?type="IBatisNet.Common.Logging.ConfigurationSectionHandler,?IBatisNet.Common"?/>????</sectionGroup>??</configSections><iBATIS>????<logging>??????<logFactoryAdapter?type="IBatisNet.Common.Logging.Impl.TraceLoggerFA,?IBatisNet.Common">????????<arg?key="showLogName"?value="true"?/>????????<arg?key="showDataTime"?value="true"?/>????????<arg?key="level"?value="ALL"?/>????????<arg?key="dateTimeFormat"?value="yyyy/MM/dd?HH:mm:ss:SSS"?/>??????</logFactoryAdapter>????</logging>??</iBATIS>

2、利用log4net輸出到文件：

??<configSections>????<sectionGroup?name="iBATIS">??????<section?name="logging"?type="IBatisNet.Common.Logging.ConfigurationSectionHandler,?IBatisNet.Common"?/>????</sectionGroup>????<section?name="log4net"?type="log4net.Config.Log4NetConfigurationSectionHandler,?log4net"?/>??</configSections> ??<iBATIS>????<logging>??????<logFactoryAdapter?type="IBatisNet.Common.Logging.Impl.Log4NetLoggerFA,?IBatisNet.Common.Logging.Log4Net">????????<arg?key="configType"?value="inline"?/>??????</logFactoryAdapter>????</logging>??</iBATIS> ??<log4net>????<!--?Define?some?output?appenders?-->????<appender?name="RollingLogFileAppender"?type="log4net.Appender.RollingFileAppender">??????<param?name="File"?value="f:\log.txt"?/>??????<param?name="AppendToFile"?value="true"?/>??????<param?name="MaxSizeRollBackups"?value="2"?/>??????<param?name="MaximumFileSize"?value="100KB"?/>??????<param?name="RollingStyle"?value="Size"?/>??????<param?name="StaticLogFileName"?value="true"?/>??????<layout?type="log4net.Layout.PatternLayout">????????<param?name="Header"?value="[Header]\r\n"?/>????????<param?name="Footer"?value="[Footer]\r\n"?/>????????<param?name="ConversionPattern"?value="%d?[%t]?%-5p?%c?[%x]?-?%m%n"?/>??????</layout>????</appender>????<appender?name="ConsoleAppender"?type="log4net.Appender.ConsoleAppender">??????<layout?type="log4net.Layout.PatternLayout">????????<param?name="ConversionPattern"?value="%d?[%t]?%-5p?%c?[%x]?&lt;%X{auth}&gt;?-?%m%n"?/>??????</layout>????</appender>????<!--?Set?root?logger?level?to?ERROR?and?its?appenders?-->????<root>??????<level?value="DEBUG"?/>??????<appender-ref?ref="RollingLogFileAppender"?/>??????<appender-ref?ref="ConsoleAppender"?/>????</root>????<!--?Print?only?messages?of?level?DEBUG?or?above?in?the?packages?-->????<logger?name="IBatisNet.DataMapper.Configuration.Cache.CacheModel">??????<level?value="DEBUG"?/>????</logger>????<logger?name="IBatisNet.DataMapper.Configuration.Statements.PreparedStatementFactory">??????<level?value="DEBUG"?/>????</logger>????<logger?name="IBatisNet.DataMapper.LazyLoadList">??????<level?value="DEBUG"?/>????</logger>????<logger?name="IBatisNet.DataAccess.DaoSession">??????<level?value="DEBUG"?/>????</logger>????<logger?name="IBatisNet.DataMapper.SqlMapSession">??????<level?value="DEBUG"?/>????</logger>????<logger?name="IBatisNet.Common.Transaction.TransactionScope">??????<level?value="DEBUG"?/>????</logger>????<logger?name="IBatisNet.DataAccess.Configuration.DaoProxy">??????<level?value="DEBUG"?/>????</logger>??</log4net>
