通常的时间滚动log配置是

<appender name="logAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${LOG_PATH}/log.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${LOG_PATH}/log_%d{yyyy-MM-dd}.log</fileNamePattern>
    </rollingPolicy>
    <encoder>
        <charset>UTF-8</charset>
        <pattern>%msg%n</pattern>
    </encoder>
</appender>

若是要实时生成带时间标记的log文件，而不是次日才能生成，那么只要去掉<file>标签就能够了app

<appender name="logAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${LOG_PATH}/log_%d{yyyy-MM-dd}.log</fileNamePattern>
    </rollingPolicy>
    <encoder>
        <charset>UTF-8</charset>
        <pattern>%msg%n</pattern>
    </encoder>
</appender>
