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Listenerxml 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。
