log4j2.xml配置： 

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="info">
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %c{2}(%F:%L) - %m%n"/>
        </Console>

        <RollingFile name="fixedTimeFileAppender" fileName="./app.log"
                     filePattern="./app.%d{yyyy-MM-dd_HH}-%i.log">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %c{2}(%F:%L) - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="500 MB"/>
            </Policies>
            <DefaultRolloverStrategy max="24"/>
        </RollingFile>

        <RollingFile name="subFixedTimeFileAppender"
                     fileName="./sub-log.log"
                     filePattern="./sub-log.log.%d{yyyy-MM-dd_HH}-%i.log">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %c{2}(%F:%L) - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="500 MB"/>
            </Policies>
            <DefaultRolloverStrategy max="24"/>
        </RollingFile>

    </Appenders>
    <Loggers>
        <!-- 特定日志 info 日志打指定文件 -->
        <AsyncLogger name="subLogger" level="info" additivity="false" includeLocation="true">
            <AppenderRef ref="subFixedTimeFileAppender"/>
        </AsyncLogger>

        <!-- 所有info 日志打文件
        <AsyncRoot level="info" includeLocation="true">
            <AppenderRef ref="fixedTimeFileAppender"/>
        </AsyncRoot>-->

        <root level="info" includeLocation="true">
            <appender-ref ref="console"/>
        </root>
    </Loggers>
</Configuration>

代码中使用：

//正常使用，日志打app.log文件
private static final Logger LOGGER = LoggerFactory.getLogger(xxx.class);
    

//打sub-log.log文件
private static final Logger LOGGER = LoggerFactory.getLogger("subLogger");
