logging.file.name, logging.file.path 不能同时生效

看一下spring的官网方文档

logging.file.name	logging.file.path	Example	Description
(none)	(none)		Console only logging.
Specific file	(none)	my.log	Writes to the specified log file. Names can be an exact location or relative to the current directory.
(none)	Specific directory	/var/log	Writes spring.log to the specified directory. Names can be an exact location or relative to the current directory.

logging.file.name 可以指定路径和log文件的名字

logging.file.path 只可以只当log的路径, 不能指定log的名字, 使用缺省值spring.log

二者只可以存在一个

#log levels

• 设置日志级别

logging:
  level:
    root: debug #指定根日志记录级别, 即全局
    com.chz.controller: trace #指定包日志记录级别
debug: true #输出更多装配信息, 但是日志不会被设为debug level

#log groups

• 管理不同包的统一日志级别

logging:
  level:
    my: error
  group:
    my: [com.chz.controller, com.chz.entity]

#自定义日志文件
