在新建的maven Spring Boot项目的pom.xml加入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
然后配置application.properties
#logging.config=classpath:log4j2.xml
#日志相关配置
logging.level.root=INFO
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate=ERROR
logging.path=/Users/xiaweiyi/Downloads/demo/logs
#logging.file=demo.log
