這篇文章主要介紹了spring boot日志報錯怎么辦，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

記錄一次報錯解決方法：

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

logging:
 path: ./logs/
 level: debug

報錯后，spring boot切換回1.5.9發(fā)現(xiàn)沒問題，因此去官網(wǎng)查找

官網(wǎng)：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
