	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext.xml</param-value>
	</context-param>
	
	<!-- 定义Struts2的FilterDispathcer的Filter -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>

	<!-- FilterDispatcher用来初始化struts2并且处理所有的WEB请求。 -->
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
     <!-- 用于初始化Spring容器的Listener -->
	<listener>
  		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 	</listener>	
    
	 <welcome-file-list>
		<welcome-file>index.html</welcome-file>
