<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<!--文件名springmvc-servlet.xml中的“springmvc”与web.xml的<servlet-name>springmvc</servlet-name>中的“springmvc”对应  -->
<beans>
<!-- HanderMapping-有3种访问Controller的方式 -->

<!--方式一  根据简单URL查找Controller-->
<!--     <bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/index">indexController</prop>
            </props>
        </property>
    </bean> 
    <bean id="indexController" class="controller.IndexController"></bean>
    -->
    
<!--方式二 根据beanname找到对应Conntroller  -->
<!-- <bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping"></bean>  
     <bean name="/index" class="controller.IndexController"></bean> --> 
    
<!--方式三  根据控制类的类名访问Controller,访问时类的类名需要小写（加不加.do均可）    http://192.168.100.47:8080/springmvc/indexController -->
    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"></bean>
    <bean class="controller.IndexController"></bean>
    
</beans>

package controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class IndexController implements Controller {
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ModelAndView mav = new ModelAndView("index.jsp");
        mav.addObject("message", "Hello Spring MVC");
        return mav;
