Spring boot 如何在application.yml中配置SpringBoot logback设置？

我想在我的项目中指定我的logback.xml文件，在我的SpringBoot应用程序中我使用了application.yml，我只是添加了

logging:
    config: logback.xml

但这对我不起作用，错误是：

 Logging system failed to initialize using configuration from 'logback.xml'

要指定配置位置，将出现相同的错误。

我该怎么办？

确保您的

logback.xml

文件位于应用程序的类路径中，例如位于打包jar文件的根目录中。然后只指定

logback.xml应该可以工作。
从注释中可以看出，您的logback配置文件位于src/main/resources中的类路径中，因此通常您可以使用：

logging:
  config: classpath:logback.xml

我只是把logback.xml放在project src/main/resources文件夹下，它也是resource文件夹，但它不起作用。你能分享logback.xml的内容吗
logging:
  config: classpath:logback.xml
