请检查spring docs以记录文件输出：https://docs.spring.io/spring-boot/docs/2.7.0/reference/htmlsingle/#features.logging.file-output
或者，您也可以使用logback-spring.xml来实现这一点。
示例logback-spring.xml在控制台和文件中打印日志，并且它每天滚动文件，或者如果它达到10MB：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<property name="LOGS" value="./logs"/> <!-- the folder where you want your log files to be -->

<appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
    <layout class="ch.qos.logback.classic.PatternLayout">
        <Pattern>
            %black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%C{1.}): %msg%n%throwable
        </Pattern>
    </layout>
</appender>

<appender name="RollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${LOGS}/spring-boot-logger.log</file>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
    </encoder>

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- rollover daily and when the file reaches 10MBs -->
        <fileNamePattern>${LOGS}/archived/spring-boot-logger-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
</appender>

<!-- LOG everything at INFO level -->
<root level="INFO">
    <appender-ref ref="RollingFile"/>
    <appender-ref ref="Console"/>
</root>
