在写完sql语句以后,如果参数有问题.还真不知道该如何看参数.原来Ibatis 是通过日志输出,看到参数的.IBatis 内置的日志输出是log4net,所以可以参考ibatis的api.照着复制其配置文件.其内容是

<configSections>
      <sectionGroup name="iBATIS">
        <section name="logging" type="IBatisNet.Common.Logging.ConfigurationSectionHandler, IBatisNet.Common" />
      </sectionGroup>
      <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
    <appSettings>
      <add key="log4net.Internal.Debug" value="true"/>
    </appSettings>
    
  <system.diagnostics>
      <trace autoflush="true">
        <listeners>
          <add name="textWriterTraceListener"
          type="System.Diagnostics.TextWriterTraceListener"
          initializeData="C:\\inetpub\\wwwroot\\log4net.txt" />
        </listeners>
      </trace>
    </system.diagnostics>
  
    <iBATIS>
      <logging>
        <logFactoryAdapter type="IBatisNet.Common.Logging.Impl.Log4NetLoggerFA, IBatisNet.Common.Logging.Log4Net">
          <arg key="configType" value="inline" />
        </logFactoryAdapter>
      </logging>
    </iBATIS>
    <log4net>
      <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
        <param name="File" value="Log/" />
        <param name="AppendToFile" value="true" />
        <!-- 切割最多文件数 -1表示不限制产生日志文件数-->
        <param name="MaxSizeRollBackups" value="-1"/>
        <!-- 每个文件的大小限制  -->
        <param name="MaximumFileSize" value="10MB"/>
        <!-- RollingStyle Composite 综合  Size 按大小  Date 按时间 -->
        <param name="RollingStyle" value="Composite" />
        <param name="DatePattern" value="&quot;&quot;yyyyMMdd&quot;.txt&quot;" />
        <param name="StaticLogFileName" value="false" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
        </layout>
      </appender>
      <root>
        <level value="ALL" />
        <appender-ref ref="RollingLogFileAppender" />
      </root>
    </log4net>

里面还有比较经典的配置log4net 是按日期输出文件的,并且不超过每天日志不超过10m.
