logback是日志的基础配置，运行时默认放在WEB-INF/classes/logback.xml
先看一下本项目的日志配置：

讲一下主要配置属性
-
<property name="logBase" value="d:\\logs\\bdp\\"/>这地方定义日志的存储根目录，实际生产中只需要改该目录就可以了。 -
<appender name="sysLogAppender"这是定义日志的种类，可以有很多 -
<file>${logBase}/sys.log</file>定义日志文件的名称 -
<rollingPolicy定义日志的滚动策略，这里定义的是当前日志后面加上-yyyyMMdd进行存储，并放在${logBase}/%d{yyyyMMdd}下面 -
<encoder>定义日志的编码格式及输出规范 -
<logger name="sysLog" additivity="false" level="info">这里定义日志名称及输出级别，一般一个日志名称对应一个日志输出 -
<logger name="org.springframework" level="INFO"/>这里定义spring的参数输出，是info级别的。
日志的配置很重要，尤其是在分布式部署的情况下， 日志的输出更为重要。
