spring boot logback滚动文件append-er不起作用

Question

我正在开发一个 Spring Boot 应用程序，我正在从 Consul 中的 YML 文件中读取 logback 配置。以下是我在 YML 文件中使用的配置。

logging:
  file: ./logs/application.log
  pattern:
    console: "%d %-5level %logger : %msg%n"
    file: "%d %-4relative [%thread] %-5level %logger{35} - %msg%n"
  level:
    org.springframework.web: ERROR
    com.myapp.somepackage: DEBUG
  appenders:
    logFormat: "%d %-4relative [%thread] %-5level %logger{35} - %msg%n"
    currentLogFilename: ./logs/application.log
    archivedLogFilenamePattern: ./logs/application-%d{yyyy-MM-dd}-%i.log.gz
    archivedFileCount: 7
    timeZone: UTC
    maxFileSize: 30KB
    maxHistory: 30 

现在生成了日志文件，但滚动附加程序不起作用，对此有任何帮助，当我们从 logback.xml 文件执行滚动附加程序时，我正在寻找类似的东西

<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <!-- daily rollover. Make sure the path matches the one in the file element or else
     the rollover logs are placed in the working directory. -->
    <fileNamePattern>./logs/myapp/application_%d{yyyy-MM-dd}.%i.log</fileNamePattern>

    <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
        <maxFileSize>5MB</maxFileSize>
    </timeBasedFileNamingAndTriggeringPolicy>
    <!-- keep 30 days' worth of history -->
    <maxHistory>30</maxHistory>
</rollingPolicy>

我需要从 YML 文件进行配置

Answer 1

经过大量搜索，我发现 Spring Boot 尚不支持此功能。选项只有：

# 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.

所以，暂时不要在这上面浪费时间。它将在 20MB 之后滚动，但文件名类似于 ${your_file_name}.log.1 等。Spring 应该支持将滚动文件名模式提供给我们。而且它不是存档文件。
