  需要说明的几点：

  1.  spring-context.xml 就是 applicationContext.xml ，此处是我改的名字。

  2.  该文件 spring-context.xml 确实在 WEB-INF 目录下。

  下面贴出 web.xml 中的配置

<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>
            classpath:/WEB-INF/spring-context.xml
        </param-value>
	</context-param>

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

  看来看去的貌似木有问题，可是为什么还会报找不到 xml的错呢？
  刚才google 一下，很多帖子给的解释是手动将 spring-context.xml 复制一份至WEB-INF/classes 目录下，可是如果我们修改了WEB-INF/spring-context.xml 文件中的内容也要修改WEB-INF/classes 目录下对应的该文件，这样比较麻烦，有木有一劳永逸的解决办法呢？

  下面给出两种解决方法...

  方法1. 我们一般会将 spring 的配置放在 WEB-INF 目录下，如果你选择了这种目录结构，那么 web.xml 中正确配置是这个样子

<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>
            classpath*:/WEB-INF/spring-context.xml
        </param-value>
</context-param>

注意classpath后面跟着个*，如果不配置那么就会报上面提到 IOException 以及 FileNotFoundException: class path resource [WEB-INF/spring-context.xml] cannot be opened because it does not exist ...

方法2. 

将 spring-context.xml 文件直接放在 src 目录下，容器每次会自动加载该文件至WEB-INF/classes 目录中。

 以上两种方法都是经过测试！环境： window 7 + Eclipse 3.7(Indigo) + jdk 6.0.30 + Spring 3.0.5
