七、为表示层项目添加日志能力 1、在Web.Config里面添加如下代码： configdivs div name="log4net" type="log4net.Config.Log4NetConfigurationdivHandler,log4net"/ /configdivs log4net root level value="INFO" / appender-ref ref="LogFileAppender" / a

七、为表示层项目添加日志能力

1、在Web.Config里面添加如下代码： <configdivs> </configdivs> <log4net> <root> <level value="INFO" /> </root> <param name="File" value="log-file.txt" /> <param name="AppendToFile" value="false" /> <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> <filter type="log4net.Filter.LevelRangeFilter"> <param name="LevelMin" value="INFO" /> <param name="LevelMax" value="WARN" /> </filter> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n"/> </layout> <filter type="log4net.Filter.LevelRangeFilter"> <param name="LevelMin" value="DEBUG" /> <param name="LevelMax" value="WARN" /> </filter> </log4net>

2、在持久层项目OfficeDAL里面Properties的AssemblyInfo.cs文件添加如下代码：

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

运行Web项目,将会在项目下生成日志文件log-file.txt

3、我们可以在持久层添加自己的日志代码，做日志输出：

观察日志文件输出:
