在做spring mvc开发的时候，报如下错误：

Could not open ServletContext resource [/WEB-INF/dispatcher-servlet.xm...

本来配置文件是没有dispatcher-servlet.xml这个文件的，为什么会报这个错呢org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/dispatcher-servlet.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/dispatcher-servlet.xml]

原来是因为web.xml里面

<servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>0</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.service</url-pattern>
    </servlet-mapping>

这样写会自动去读dispatcher-servlet.xml ，
