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>
