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="http://www.mamicode.com/views/"></property>
        <property name="suffix" value="http://www.mamicode.com/.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="http://www.mamicode.com/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>
