web.xml以其中一个为例<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <!--核心控制器的配置 DispatcherServlet-->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc-servlet-myView.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

一 ：
MultiActionController配置文件：   
   <!--处理器映射器 -->
    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/*.do">
                    <value>multiController</value>
                </entry>
            </map>
        </property>
    </bean>

    <!--注册Hanlder  处理器-->
    <bean id="multiController" class="cn.happy.controller.multiactionController">
    </bean>

    <!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

继承MultiActionController
public class multiactionController extends MultiActionController {

    public ModelAndView doinsert(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView model=new ModelAndView();
        model.setViewName("insert");
        return model;
    }
}
二：
MultiActionController配置文件：（另一种形式）
 <!--1-->
    <!--处理器适配器-->
    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/*" value="PropertiesmultiController"></entry>
            </map>
        </property>
    </bean>
    <!--属性方法名称解析器 http://localhost:8080/first.do-->
    <bean id="propertiesMethodResovler" class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
        <property name="mappings">
            <props>
                <prop key="/first.do">doinsert</prop>

            </props>
        </property>
    </bean>
    <!--2-->
    <!--参数方法名称解析器  http://localhost:8080/hello.do?actionName=doinsert-->
   <!-- <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/hello.do">PropertiesmultiController</prop>
            </props>
        </property>
    </bean>
    <bean id="paramMethodResovler" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName" value="actionName"></property>
    </bean>-->

    <!--注册Hanlder  处理器   ref=paramMethodResovler/propertiesMethodResovler-->
    <bean id="PropertiesmultiController" class="cn.happy.controller.PropertiesMultiAction">
        <property name="methodNameResolver" ref="propertiesMethodResovler"></property>
     </bean>



    <!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

继承MultiActionController
	public class PropertiesMultiAction extends MultiActionController{
    public ModelAndView doinsert(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView model=new ModelAndView();
        model.setViewName("insert");
        return model;
    }

}

三：
配置文件一：    <!--1  http://localhost:8080/first.do  -->
    <!--属性方法名称解析器 http://localhost:8080/first.do-->
    <!--<bean id="propertiesMethodResovler" class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
        <property name="mappings">
            <props>
                <prop key="/first.do">dodelete</prop>
            </props>
        </property>
    </bean>-->


    <!--2  http://localhost:8080/hello.do?actionName=doinsert  京东-->
    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/*" value="myViewController"></entry>
            </map>
        </property>
    </bean>
     <!--引入视图对象-->
   <bean class="org.springframework.web.servlet.view.XmlViewResolver">
       <property name="location" value="classpath:myView.xml"></property>
    </bean>
    <!--视图解析器-->
    <bean id="beanNameResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver"/>


    <!--注册Hanlder  处理器  paramMethodResovler/propertiesMethodResovler-->
    <bean id="myViewController" class="cn.happy.controller.MyViewResovler">
        <property name="methodNameResolver" ref="paramMethodResovler"></property>
     </bean>

    <bean id="paramMethodResovler" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName" value="actionName"></property>
    </bean>


    <!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
配置文件二：

   <!--内部视图：视图对象-->
    <bean id="internalResource" class="org.springframework.web.servlet.view.JstlView">
        <property name="url" value="/WEB-INF/insert.jsp"></property>
    </bean>
    <!--外部视图   http://localhost:8080/hello.do?actionName=doinsert-->
    <bean id="jd" class="org.springframework.web.servlet.view.RedirectView">
        <property name="url" value="https://www.jd.com/"></property>
    </bean>
继承MultiActionController
	public class MyViewResovler extends MultiActionController{
    public ModelAndView doinsert(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView model=new ModelAndView();
        model.setViewName("jd");
        return model;
    }
    public ModelAndView dodelete(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView model=new ModelAndView();
        model.setViewName("internalResource");
        return model;
    }
}
