Question

我知道log4cxx配置文件的rollingPolicy参数，但我无法设置配置文件，它可以告诉记录器每个新的一天创建一个新文件，我怎么能实现这个结果？

Answer 1

是。使用Composite的滚动样式：

   <appender name="LogAppender" type="log4net.Appender.RollingFileAppender">
    <file type="log4j.Util.PatternString" value="LogFile.log" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value="yyyyMMdd" />
    <maxSizeRollBackups value="7" />
    <maximumFileSize value="100MB" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date{ISO8601}: [%2thread] %-5level %logger: '%P{network}.%P{node}' %message%newline" />
    </layout>
    </appender>

我认为以下的appender会做这些东西（无法在这台PC上测试）

    <!-- the following appender with the name "TimeBasedLog.log", every night a few seconds after
     12::00PM the old log will be renamed with append the date in filename, and a new log file
     with the name "TimeBasedLog.log" will be create. 
     notice the RollingFileAppender is under "org.apache.log4j.rolling" namespace
-->
<appender name="MyRollingAppenderDaily" class="org.apache.log4j.rolling.RollingFileAppender">
    <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
        <param name="FileNamePattern" value="TimeBasedLog.%d{yyyy-MM-dd}.log"/>
        <param name="activeFileName" value="TimeBasedLog.log"/>
    </rollingPolicy>

    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss,SSS} %x [%p] (%F:%L) %m%n"/>
    </layout> 
    <param name="file" value="TimeBasedLog.log"/>
    <param name="append" value="true"/>
</appender>

我想知道是否可以在appender内部结合timebasedrollingpolicy和MaxFileSize / MaxBackupIndex功能？

        <param name="MaxFileSize" value="5KB"/>
    <param name="MaxBackupIndex" value="5"/>
