我是靠谱客的博主自觉棉花糖，这篇文章主要介绍springMVC中contextConfigLocation与DispatcherServlet的关系，现在分享给大家，希望可以做个参考。

<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>

</servlet-mapping>

该DispatcherServlet默认使用WebApplicationContext作为上下文，Spring默认配置文件为“/WEB-INF/[servlet名字]-servlet.xml”。

<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
