在web.xml中通过contextConfigLocation配置spring，<span style="font-family: 新宋体;">contextConfigLocation</span> 参数定义了要装入的 Spring 配置文件。如果想装入多个配置文件，可以在 <code><param-value></code> 标记中用逗号作分隔符。---------------------------------------------------------------

在web.xml里配置Listener

xml 代码如下： 

  < listener >  

       <    listener-class > org.springframework.web.context.ContextLoaderListener listener-class >  

  <   /  listener >   

如果在web.xml里给该Listener指定要加载的xml,如：

xml代码如下：

<!-- spring config -->

      <context-param>

           <param-name>contextConfigLocation</param-name>  

           <param-value>classpath:applicationContext.xml</param-value>

      </context-param>

则会去加载相应的xml,而不会去加载/WEB-INF/下的applicationContext.xml。

但是，如果没有指定的话，默认会去/WEB-INF/下加载applicationContext.xml。
