刚开始学maven，本人把配置文件放在了如下目录：

web.xml是这样配置的：

	<servlet>
		<servlet-name>springMvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:conf/applicationContext.xml</param-value>
		</init-param>
		<load-on-startup>2</load-on-startup>
	</servlet>

报错：

发现启动之后还是去WEB-INF下找本人的配置文件，本人给WEB-INF下再放一份就不报错了。求帮助为何？
