# 一 配置日志级别 #

日志记录器（Logger）的行为是分等级的。分为：OFF、FATAL、ERROR、WARN、INFO、DEBUG、ALL

默认情况下，spring boot 从控制台打印出来的日志级别只有 INFO 及以上级别，可以配置日志级别

# 设置日志级别
    logging.level.root=WARN

这种方式只能将日志打印在控制台上

# 二 Logback 日志 #

spring boot 内部使用 Logback 作为日志实现的框架。

Logback 和 log4j 非常相似，如果你对 log4j 很熟悉，那对 logback 很快就会得心应手。

# 三 配置日志 #

resources/logback-spring.xml的一般配置
