logback的SizeBasedTriggeringPolicy和TimeBasedRollingPolicy联合使用问题

<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>/var/log/testglog</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>/var/log/test.%d{yyyy-MM-dd}.log</fileNamePattern>
<!-- keep 30 days' worth of history -->
<maxHistory>30</maxHistory>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>10MB</maxFileSize>
</triggeringPolicy>
<encoder >
<Pattern>%-15d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{0}[%file:%line] - %msg%n %ex{2}</Pattern>
<charset>UTF-8</charset>
<immediateFlush>true</immediateFlush>
</encoder>
</appender>

 

上面SizeBasedTriggeringPolicy和TimeBasedRollingPolicy联合使用方式有问题，当size超过10M后并没有触发TimeBasedRolling生效，见http://jira.qos.ch/browse/LOGBACK-73

正确的配置是：Size and time based archiving
