1.  web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.4" 
    	xmlns="http://java.sun.com/xml/ns/j2ee" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
      
      
      
      <servlet>
      	<servlet-name>springMVC</servlet-name>
      	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      	<load-on-startup>0</load-on-startup> 
      </servlet> 
      <servlet-mapping>
      	<servlet-name>springMVC</servlet-name>
      	<url-pattern>/</url-pattern>
      </servlet-mapping>
      
    </web-app>

1.  springMVC-servlet

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    ">
    
    
    
    <bean name="/hello.do" class="com.controller.HelloController"></bean>
    <bean name="/hello2.do" class="com.controller.HelloController2"></bean>
    
    
    
    <mvc:resources location="/" mapping="*.html"/>
    
    
    </beans>

1.  HelloController.java

package com.controller;
    
    import java.io.IOException;
    
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import org.springframework.web.HttpRequestHandler;
    
    public class HelloController implements HttpRequestHandler {
    	@Override
    	public void handleRequest(HttpServletRequest req, HttpServletResponse resp)
    			throws ServletException, IOException {
    		System.out.println("请求过来了");
    		resp.sendRedirect("index.jsp");
    		
    	}
    	
    }

1.  HelloController2.java

package com.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 HelloController2 implements Controller {
    
    	@Override
    	public ModelAndView handleRequest(HttpServletRequest req,
    			HttpServletResponse resp) throws Exception {
    		ModelAndView mv = new ModelAndView();
    		//将数据和视图一起封装并返回
    		mv.setViewName("index.jsp");
    		mv.addObject("name", "bwf");
    		return mv;
    	}
    
    }
