在src/main/resources/下新建  
**logback-spring.xml**

            <appender-ref ref="fileErrorLog" />
        </root>
    
    </configuration>

如果只是想简单使用的话，也可以直接在application.yml中配置

logging:
      file: f:/mylog/test-log.log
      pattern:
        console: "%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger{36} %line -%msg%n"
        file: "%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger{36} %line -%msg%n"
      level:
        root: info
        com.example: debug
