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

logging:
path:./logs/
level:debug

报错后，springboot切换回1.5.9发现没问题，因此去官网查找

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

看到这部分

26.4LogLevels

AllthesupportedloggingsystemscanhavetheloggerlevelssetintheSpringEnvironment(forexample,inapplication.properties)byusinglogging.level.=wherelevelisoneofTRACE,DEBUG,INFO,WARN,ERROR,FATAL,orOFF.Therootloggercanbeconfiguredbyusinglogging.level.root.

Thefollowingexampleshowspotentialloggingsettingsinapplication.properties:

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

看完这部分，将yml改为如下：

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

再次重启，问题解决
