1.web.xml中SpringMVC配置

/webapp/WEB-INF/web.xml

<!-- springMVC前置控制器的配置 --> 
 <servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <!-- springMVC配置文件 --> 
   <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/config/mvc-dispatcher-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 拦截URL中包含[/]的请求 -->
 <servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>


2.SpringMVC配置文件
/WEB-INF/config/mvc-dispatcher-servlet.xml
 <beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
