请问这个是怎么回事？在线等待，，，，
------解决方案--------------------------------------------------------
配置监听，初始化没有找到所需的监听
------解决方案--------------------------------------------------------
是不是少配了这个？
<listener>
<description>Spring 监听器</description>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
------解决方案--------------------------------------------------------
缺少jar包，添加jar包就可以啦，commons-logging
------解决方案--------------------------------------------------------
要学会看错误信息，一般都是前几行，
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
这里提示找不到类，这时候你去看他找不到什么类，
然后百度搜索“org/apache/commons/logging/LogFactory”，不出意外的话之前这种很普遍的问题之前应该会有别人也遇到过，所以肯定有相应的解决方法，之后根据解决方法去做就可以了。
