由于代码很多地方相识，以下我只说Service.A,和Service.A.Service；
Service.A 中新增Configs文件夹，下面添加log4net.config，log4net.config代码如下：
<log4net> <root> <level value="Error" /> <!-- <appender-ref ref="RollingLogFileAppender" /> --> <appender-ref ref="ErrorRollingLogFileAppender" /> </root> <appender type="log4net.Appender.RollingFileAppender,log4net" LEVEL="ERROR"> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <param value="c:\surging\Error\" /> <param value="true" /> <param value="Composite" /> <param value="_yyyyMMddHH.TXT" /> <param value="false" /> <param value="-1" /> <param value="5MB" /> <layout type="log4net.Layout.PatternLayout,log4net"> <param value="%date [%thread] %-5level %logger [%ndc] - %message%newline" /> </layout> <filter type="log4net.Filter.LevelRangeFilter"> <param value="ERROR" /> <param value="FATAL" /> </filter> </appender> </log4net>
