的logback RollingFileAppender进行maxHistory

Question

我的配置：

<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender"> 
    <file>/logs/logFile.log</file> 
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> 
     <pattern>${PATTERN}</pattern> 
    </encoder> 

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 

     <fileNamePattern>/logs/logFile.%d{yyyy-MM-dd}.%i.log</fileNamePattern> 
     <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> 
      <maxFileSize>1MB</maxFileSize> 
     </timeBasedFileNamingAndTriggeringPolicy> 
     <maxHistory>2</maxHistory> 
    </rollingPolicy> 
</appender> 

但是，日志不会两天后删除，可能是什么问题呢？ 也许问题：

<fileNamePattern>/logs/logFile.%d{yyyy-MM-dd}.%i.log</fileNamePattern> 

但我需要将所有日志保存

请设置

<cleanHistoryOnStart>true</cleanHistoryOnStart> 

和检查。这在默认情况下是错误的。
