yml配置方法一

##########################
##logging配置方法一
logging:
  pattern:
    console: "%d - %msg%n"     #日志输出格式：日期 - 日志信息
  #path: E:\javawork\log
  file: E:\javawork\log\sell.log        #日志输出到文件
  file: E:\javawork\log\sell.%d.log  #日志输出到文件
  level:
    com.muyang.diancan: debug   #指定需要日志输出的包:com.muyang.diancan是项目的个根目录（根包），
##########################
