1. 创建一个web工程

2. 导入依赖包

3.创建springmvc的配置文件

配置中央控制器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<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>*.do</url-pattern>
	</servlet-mapping>

创建springmvc的核心配置文件

文件的命名规则：中央控制器（servlet的名称）的名称+“-servlet.xml”

默认位置：WEB-INF下

配置：controller和视图解析器

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
			http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
			http://www.springframework.org/schema/mvc 
			http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 
			http://www.springframework.org/schema/context 
			http://www.springframework.org/schema/context/spring-context-3.0.xsd 
			http://www.springframework.org/schema/aop 
			http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
			http://www.springframework.org/schema/tx 
			http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
			<!-- controller , handlerMapping, ViewResolver, interceptor -->
			<!-- controller的配置，注意name后面必须的要配置.do -->
			<bean id="testController" name="/hello.do" class="com.hao947.SpringMVC"></bean>
			<!-- handlerMapping 默认的配置式采用controller的bean的name来访问controller -->
			
			<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			
				<property name="prefix" value="/WEB-INF/jsp/"></property>
				<property name="suffix" value=".jsp"></property>
			</bean>
			
</beans>

4. 创建controller

package com.hao947;

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

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

public class SpringMVC extends AbstractController{

	@Override
	protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
			HttpServletResponse arg1) throws Exception {
		System.out.println("hello springmvc");
		return new ModelAndView("index");
		
	}

}
