springMVC的配置文件的配置。

问题：IOException parsing XML document from ServletContext resource [/WEB-INF/application.xml

我把web.xml中的全局的

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mvc.xml</param-value>
    </context-param>
注释以后报出以上的错误了。
注释去掉以后不会报错了。我很纳闷的是springMVC的servlet上配置了contextConfigLocation，但是在web.xml的全局还要再配置一次。
