Project initialization, managing projects using logback log when the error will be started directly as shown above:

Only you need .yml configuration file, add the following configuration:

#logback配置
logging:
  pattern:
    console: '%d -%msg%n'
  path: D:/data/log/seller.log
  level:
    root: debug
