logback + slf4j 学习

1:在web.xml文件配置Listener

<context-param>

<param-name>logbackConfigLocation</param-name>
<param-value>classpath:logback.xml</param-value> <!-- classpath是指 WEB-INF文件夹下的classes目录 -->
</context-param>
<listener>
<listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>
</listener>

2:logback.xml文件内容
