Springboot项目使用Slf4j将日志保存到本地目录

1.引入jar包

    org.slf4j
    slf4j-api
    1.7.25

2.编写application.properties/yml

#.properties
logging.config= classpath:logback-spring.xml
logging.file= #存放路径

#.yml
logging:
    config: classpath:logback-spring.xml
    file: #存放路径

3.编写logback-spring.xml
我们在src/main/resources中创建一个logback-spring.xml，注意：-spring在application之后可以扫描到，如果只写logback.xml那么该xml就会优先于application.yml进行扫描，因此无效

logback-spring
