问题描述

我想通过log4j2配置生成半日日志文件.我给了:

I want to generate half-daily log files through log4j2 configuration. I have given :

<RollingFile name="fileAppender" filename ="${logName} append="true" 
    FilePattern="${logName}. %d{yyyy-MM-dd-a}">

有人可以帮我吗?

推荐答案

您可以为此使用CronTriggeringPolicy.我从

You can use the CronTriggeringPolicy for this. I borrowed the expression from the answer at Cron Expression (Quartz) for a program to run every midnight at 12 am for the actual expression to use.

<RollingFile name="fileAppender" filename ="${logName} append="true" FilePattern="${logName}.$$d{yyyy-MM-dd-a}">
    <CronTriggeringPolicy schedule="0 0 0,12 * * ?" />
</RollingFile>
