*  创建SpringMVC项目的web.xml预设文件

<?xml version="1.0" encoding="UTF-8" ?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
    
    
    
      
        <servlet>
    
            <servlet-name>springmvc</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        </servlet>
    
    
    
    
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>
    
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
    </web-app>

*  在web-inf下面找一个springmvc-servlet.xml的文件

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    	
            <context:component-scan base-package="com.zcq.controller"/>
    
    
    
    
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    
    
            <property name="prefix" value="/jsp/"/>
    	
            <property name="suffix" value=".jsp"/>
        </bean>
    
    	<bean class="com.zcq.controller.HelloController" name="/helloController">
    
        </bean>
    </beans>

*  controller代码

package com.zcq.controller;
    
    import org.springframework.web.servlet.ModelAndView;
    import org.springframework.web.servlet.mvc.Controller;
    
    //实现一个Controller接口的方式
    public class HelloController implements Controller { 
    
        @Override
        public ModelAndView handleRequest(javax.servlet.http.HttpServletRequest httpServletRequest, 
        	javax.servlet.http.HttpServletResponse httpServletResponse) 
        	throws Exception { 
        	
            ModelAndView mav = new ModelAndView();
            mav.addObject("girl","菲菲");
            mav.setViewName("girl");
            return mav;
            
        }
    }

*  view代码

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>Girl</title>
    </head>
    <body>
        我的脑海： ${girl}
    </body>
    </html>
