logback读取application.yml中的值实现多环境

application.yml的配置：

# 日志配置  为空为项目跟目录下的logs  或者指定已经存在的目录
log:
  path:

logback配置

<?xml version="1.0" encoding="UTF-8"?>
<!--
说明：
    1. 文件的命名和加载顺序有关
       logback.xml早于application.yml加载，logback-spring.xml晚于application.yml加载
       如果logback配置需要使用application.yml中的属性，需要命名为logback-spring.xml
    2. logback使用application.yml中的属性
       使用springProperty才可使用application.yml中的值 可以设置默认值
