1.cope   jar包到lib中

2.配置web.xml文件

<servlet>

        <servlet-name>springmvc</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    </servlet>

    <!-- Map all requests to the DispatcherServlet for handling -->

    <servlet-mapping>

        <servlet-name>springmvc</servlet-name>

        <url-pattern>*.do</url-pattern>

    </servlet-mapping>

3.在web-inf中创建springmvc的配置文件springmvc-servlet.xml

分别配置注解驱动、扫描器、视图解析器

<!-- springmvc注解驱动 -->

    <mvc:annotation-driven/>

    <!-- 扫描器 -->

    <context:component-scan base-package="com.tideway.springmvc"></context:component-scan>

    <!-- 配置视图解析器 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/views/"></property>

        <property name="suffix" value=".jsp"></property>

    </bean>

4.创建发送请求页面index.jsp

<form action="hello.do" method="post">

        ID:<input type="text" name="userName"/>

        <input type="submit" value="submit"/>

    </form>

5.创建控制器HelloWorld.java

package com.tideway.springmvc;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

public class HelloWorld {

    @RequestMapping(value="/hello.do")

    public String hello(String userName,Model model){

        System.out.println(userName);

        model.addAttribute("helloworld", "Hello:"+userName);

        return "success";

    }

}

6.在WebContent文件夹下创建views文件夹下创建响应页面success.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

    pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<title>Insert title here</title>

</head>

<body>

<!-- el方式 -->

<h1>${helloworld }</h1>

</body>

</html>
