web.xml 配置：

<servlet>
	<servlet-name>dispatcher</servlet-name>
	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	<init-param>
		<description>加载/WEB-INF/spring-mvc/目录下的所有XML作为Spring MVC的配置文件</description>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/spring-mvc/*.xml</param-value>
	</init-param>
	<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
	<servlet-name>dispatcher</servlet-name>
	<url-pattern>*.htm</url-pattern>
</servlet-mapping>

这样，所有的.htm的请求，都会被DispatcherServlet处理；

初始化 DispatcherServlet 时，该框架在 web 应用程序WEB-INF 目录中寻找一个名为[servlet-名称]-servlet.xml的文件，并在那里定义相关的Beans，重写在全局中定义的任何Beans，像上面的web.xml中的代码，对应的是dispatcher-servlet.xml；当然也可以使用<init-param>元素，手动指定配置文件的路径；

dispatcher-servlet.xml 配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"

    <!--
        使Spring支持自动检测组件，如注解的Controller
    -->
    <context:component-scan base-package="com.minx.crm.web.controller"/>
   
    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp" />
</beans>
