springboot讀取logback-spring.xml

官網地址：https://docs.spring.io/spring-boot/docs/1.3.8.RELEASE/reference/html/boot-features-logging.html

在類LoggingApplicationListener進行spring日誌初始化。

通過環境變量對象獲取logging.conf配置，如果不存在則忽略配置方式啓動日誌、否則使用logging.conf日誌配置文件初始化啓動日誌。

由LoggingSystem實現類LogbackLoggingSystem完成初始化操作。

 

springboot-1.3.8加載日誌對象堆棧信息
