logback的日志配置文件
日志配置文件logback.xml:

部署运行后发现,在Linux下面 tomcat的日志文件catalina.out增长速度很快,造成愈来愈大;
修改tomcat/conf/logging.peoperties 将
1catalina.org.apache.juli.FileHandler.level = FINE
改为
1catalina.org.apache.juli.FileHandler.level = WARNING

因为:
Tomcat 日志分为下面5类:
catalina 、 localhost 、 manager 、 admin 、 host-manager
每类日志的级别分为如下 7 种:
SEVERE (highest value) > WARNING > INFO > CONFIG > FINE > FINER > FINEST (lowest value)
