application.yml中的原配置如下：(spring boot版本2.0.4)

logging:
 path: ./logs/
 level: debug

報錯後，spring boot切換回1.5.9發現沒問題，因此去官網查詢

官網：https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-custom-log-levels

看到這部分

26.4 Log Levels

All the supported logging systems can have the logger levels set in the Spring Environment (for example,in application.properties) by using logging.level.<logger-name>=<level> where level is one of TRACE,DEBUG,INFO,WARN,ERROR,FATAL,or OFF. The root logger can be configured by using logging.level.root.

The following example shows potential logging settings in application.properties:

logging.level.root=WARN
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate=ERROR

看完這部分，將yml改為如下：

logging:
 path: ./logs/
 level:
 root: debug

再次重啟，問題解決

以上這篇基於spring boot 日誌(logback)報錯的解決方式就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援我們。
