        </rollingPolicy>

    </appender>

    <logger name="com.logBack.demo" level="debug"
            additivity="false">
        <appender-ref ref="FILE" />
        <appender-ref ref="STDOUT" />

    <root level="error" additivity="false">
        <appender-ref ref="FILE" />
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

这是我的logback-spring.xml文件，但是当我运行应用程序时，日志在控制台中正确显示，但未在指定位置创建日志文件。我正在使用Windows系统，因此理想情况下，日志文件应在c：/logs/tomcat/LogBackDemo/logback/app_LogBackDemo.log位置中创建。

Answer 1

我使用了您的确切文件（已删除<withJansi>true</withJansi>），并且当日志配置文件保存在资源文件夹（src \ main \ resources \ logback-spring.xml）中时，它正在创建日志文件。我已经修改了按照我的软件包名称com.logBack.demo（记录器名称），然后打印日志。

您可以使用以下属性并轻松设置日志记录，包括Spring Boot中带有application.property文件的日志文件。

# LOGGING
logging.config= # Location of the logging configuration file. For instance `classpath:logback.xml` for Logback
logging.exception-conversion-word=%wEx # Conversion word used when logging exceptions.
logging.file= # Log file name. For instance `myapp.log`
logging.level.*= # Log levels severity mapping. For instance `logging.level.org.springframework=DEBUG`
logging.path= # Location of the log file. For instance `/var/log`
logging.pattern.console= # Appender pattern for output to the console. Only supported with the default logback setup.
logging.pattern.file= # Appender pattern for output to the file. Only supported with the default logback setup.
logging.pattern.level= # Appender pattern for log level (default %5p). Only supported with the default logback setup.
logging.register-shutdown-hook=false # Register a shutdown hook for the logging system when it is initialized.

如果您想使用特殊的xml文件（我不喜欢），则可以进行检查， https://www.baeldung.com/spring-boot-logging

如果您仍然遇到麻烦，请告诉我

Answer 2

我有同样的问题。我只是从文件系统中删除logback.xml并再次创建它就可以了

Logback未在SpringBoot中创建日志文件
