1.默认情况下直接依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId> </dependency>
2.创建一个名为：logback-spring.xml的文件
3.在yml配置文件中激活
注：优先级logback.xml(默认) > logback-spring.xml，如果发现不生效时，检查下配置是否存在覆盖
# logging配置
logging:level:root: infoconfig: classpath:logback-spring.xml
4.下面为可以进行参考的xml配置
