logback的日志配置文件

日志配置文件logback.xml:

             RollingFileAppender 一般情况下需要配置两个参数：

             RollingPolicy，负责滚动。TriggeringPolicy，决定是否以及何时进行滚动

             TimeBasedRollingPolicy比较特殊，它同时继承了RollingPolicy和TriggerPolicy。

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

# To see debug messages in TldLocationsCache, uncomment the following line:

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)
