IBatis.net 输出SQL语句（七）

一、IBatis.net输出SQL语句到控制台

　　输出IBatis.net生成的SQL语句到控制台，能够方便调试。

　　如果要想输出IBatis.net的SQL语句到控制台，那么只需要做如下配置即可：

<configSections>
<!-- 输出IBatis.net执行的SQL语句到控制台 -->
<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>

　　那么显示结果如下：

二、IBatis.net输出SQL语句到文件

　　另外，利用log4net，能够很轻易地把SQL语句生成到文件上。

　　只需做如下配置：

<configSections>
<!-- 输出IBatis.net执行的SQL语句 -->
<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>
<!-- 定义输出的附加信息，大小，输出到的文件等等 -->
<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] <%X{auth}> - %m%n" />
</layout>
</appender>

<!-- 设置错误的级别以及附加信息 -->
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="ConsoleAppender" />
</root>

<!-- 只是打印错误信息的级别 -->
<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>
