spring boot log 多环境配置
前言
bootstrap.yml（bootstrap.properties）与application.yml（application.properties）执行顺序
bootstrap.yml（bootstrap.properties）用来程序引导时执行，应用于更加早期配置信息读取，如可以使用来配置application.yml中使用到参数等
application.yml（application.properties) 应用程序特有配置信息，可以用来配置后续各个模块中需使用的公共参数等。
bootstrap.yml 先于 application.yml 加载
1.第一种方法，直接写在application.yml里面，也能适配环境修改，但是只能使用默认一些策略，比如10M切分一个文件。
#日志配置
logging:
level:
root: INFO
file: /home/xxx/logs/xxx.log2.第二种方法 logback-spring.xml
%d [%thread] %-5level %logger{36} - %msg%n
ERROR
DENY
ACCEPT
%d [%thread] %-5level %logger{36} - %msg%n
${logHome}/%d/info/info.log
30
ERROR
%d [%thread] %-5level %logger{36} - %msg%n
${logHome}/%d/error/error.%i.log
30
2MB
10MB
一开始在application.yml 配置了log路径，但是springProperty 标签里面并没有获取到，会见在jar包存放的文件夹下，新建logHome_IS_UNDEFINED/%d/info/info.log，看下启动日志（一部分）：
