入门案例：

搭建需要的jar类以下两个为MVC需要的jar

<!--SpringWeb--><dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-web</artifactId>  <version>4.2.8.RELEASE</version></dependency>

<!--SpringWebMVC--><dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-webmvc</artifactId>  <version>4.2.8.RELEASE</version></dependency>

resources  配置如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:p="http://www.springframework.org/schema/p"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:mvc="http://www.springframework.org/schema/mvc"       xsi:schemaLocation="        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd        http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx.xsd        http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<bean id="/hello.do" class="cn.bdqn.FirstController"></bean>

webapp中创建index.jsp 里面内容任意

在web.xml中配置servlet

<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.xml</param-value>  </init-param>  <load-on-startup>1</load-on-startup></servlet>

java中创建  一个类 调用index.jsp

public class FirstController implements Controller {    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {       ModelAndView mv=new ModelAndView();           mv.setViewName("/WEB-INF/index.jsp");        return mv;    }}
