Log4J: How to keep log file after midnight

Can one configure log4j RollingFileAdapter not to change logfile name after midnight? With the configuration (see below) I'm using, if the logging starts on 2017-09-15 and continues overnight everything after 00:00 will be logged to another logfile 2017-09-16. I'd like to get full log in to the same file. Only if another run starts on 2017-09-16 then a new log would be created.

<appender name="file-output" class="org.apache.log4j.rolling.RollingFileAppender">
    <param name="ImmediateFlush" value="false"/>
    <param name="Threshold" value="INFO"/>
    <rollingPolicy name="file" class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
        <param name="FileNamePattern" value="log/${logfilename}_%d{yyyy-MM-dd}.log"/>
    </rollingPolicy>
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p %m%n"/>
    </layout>
</appender>

sounds like you donot need ROTATE file appender.

in your situation, i will advise you just use normarl file appender, this will make all log records into one file. all you need to do is name it by date pattern, like "yyyy-MM-dd.log".

ps: if you want rotate, logrorate tool on linux is a good choice too.
