 //开启调试
 <!— Define some output appenders —>
 <appender name="FileAppender" type="log4net.Appender.RollingFileAppender">
 <file value="log\log.txt" />

<!—追加日志内容—>
 <appendToFile value="true" />

<!—防止多线程时不能写Log,官方说线程非安全—>
 <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

<!—可以为:Once|Size|Date|Composite—>
 <!—Composite为Size和Date的组合—>
 <rollingStyle value="Composite" />

<!—当备份文件时,为文件名加的后缀—>
 <datePattern value="yyyyMMdd.txt" />

<!—日志最大个数,都是最新的—>
 <!—rollingStyle节点为Size时,只能有value个日志—>
 <!—rollingStyle节点为Composite时,每天有value个日志—>
 <maxSizeRollBackups value="3" />

<!—可用的单位:KB|MB|GB—>
 <maximumFileSize value="2KB" />

<!—置为true,当前最新日志文件名永远为file节中的名字—>
 <staticLogFileName value="true" />

<!—输出级别在INFO和ERROR之间的日志—>
