官网说明：Size and time based rolling policy
Sometimes you may wish to archive files essentially by date but at the same time limit the size of each log file, in particular if post-processing tools impose size limits on the log files. In order to address this requirement, logback ships with
SizeAndTimeBasedRollingPolicy.
有时候你本来是希望按照日期来对日志进行归档，但是同时你又希望限制每个日志文件的大小，为了满足这一需求，logback提供了SizeAndTimeBasedRollingPolicy.
Note that
TimeBasedRollingPolicyalready allows limiting the combined size of archived log files. If you only wish to limit the combined size of log archives, thenTimeBasedRollingPolicydescribed above and setting the totalSizeCap property should be amply sufficent.
注意,TimeBasedRollingPolicy已经允许限制合并归档日志文件的大小。如果你只希望限制合并归档日志的大小,TimeBasedRollingPolicy中设置totalSizeCap即可：
Here is a sample configuration file demonstrating time and size based log file archiving.
Example: Sample configuration for
SizeAndTimeBasedFNATP(logback-examples/src/main/resources/chapters/appenders/conf/logback-sizeAndTime.xml)
下面是一个示例配置文件说明基于时间和大小的日志文件归档。
View as .groovy
<configuration> <appender name="ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>mylog.txt</file> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <!-- rollover daily --> <fileNamePattern>mylog-%d{yyyy-MM-dd}.%i.txt</fileNamePattern> <!-- each file should be at most 100MB, keep 60 days worth of history, but at most 20GB --> <maxFileSize>100MB</maxFileSize> <maxHistory>60</maxHistory> <totalSizeCap>20GB</totalSizeCap> </rollingPolicy> <encoder> <pattern>%msg%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="ROLLING" /> </root> </configuration>
Note the "%i" conversion token in addition to "%d". Both the %i and %d tokens are mandatory. Each time the current log file reaches maxFileSize before the current time period ends, it will be archived with an increasing index, starting at 0.
注意：“%i"”转换标记除了“% d”。%i"和% d令牌都是强制性的。每次当前日志文件之前到达maxFileSize当前时间段结束时,它将存档增加索引从0开始。
Size and time based archiving supports deletion of old archive files. You need to specify the number of periods to preserve with the maxHistory property. When your application is stopped and restarted, logging will continue at the correct location, i.e. at the largest index number for the current period.
基于大小和时间的归档支持删除旧存档文件。您需要指定使用maxHistory属性保留的时期数量。当应用程序停止并重新启动时，日志记录将在正确的位置继续，即当前期间的最大索引号。
In versions prior to 1.1.7, this document mentioned a component called
SizeAndTimeBasedFNATP. However, given thatSizeAndTimeBasedFNATPoffers a simpler configuration structure, we no longer documentSizeAndTimeBasedFNATP. Nevertheless, earlier configuration files usingSizeAndTimeBasedFNATPwill continue to work just fine. In fact,SizeAndTimeBasedRollingPolicyis implemented with aSizeAndTimeBasedFNATPsubcomponent.
在1.1.7之前的版本中，本文档提到了一个名为SizeAndTimeBasedFNATP的组件。但是，考虑到SizeAndTimeBasedFNATP提供了更简单的配置结构，我们不再记录SizeAndTimeBasedFNATP。不过，使用SizeAndTimeBasedFNATP的早期配置文件将继续正常工作。实际上，SizeAndTimeBasedRollingPolicy是用SizeAndTimeBasedFNATP子组件实现的。
Logback.xml:同时按照日期和大小分割日志
有两种形式： 最新的日志，是日期最大数字最大的 最新的日志，是没有日期没有数字的
