1.创建dynamic web Project项目
2.加入jar包

commons-logging-1.1.1.jarspring-aop-4.0.4.RELEASE.jarspring-beans-4.0.4.RELEASE.jarspring-context-4.0.4.RELEASE.jarspring-core-4.0.4.RELEASE.jarspring-expression-4.0.4.RELEASE.jarspring-web-4.0.4.RELEASE.jarspring-webmvc-4.0.4.RELEASE.jar

3.在web.xml中配置DispatcherServlet

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns="http://xmlns.jcp.org/xml/ns/javaee"    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"    id="WebApp_ID" version="3.1">    <!-- 配置DispatcherServlet -->    <servlet>        <servlet-name>dispatcherServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!—配置 DispatcherServlet的一个初始化参数，指定配置springmvc配置文件的位置    ***实际上也可以不通过contextConfigLocation来进行配置，可以使用默认的文件文件名称，默认的配置文件名称为：/WEB-INF/<servlet-name>-servlet.xml***-->        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:springmvc.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>dispatcherServlet</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping></web-app>

4.加入springmvc的配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:context="http://www.springframework.org/schema/context"     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/context         http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc.xsd">    <!-- 配置自动扫描包 -->    <context:component-scan base-package="cn.hq.handler"></context:component-scan>    <!-- 配置视图解析器 -->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/WEB-INF/views/"></property>        <property name="suffix" value=".jsp"></property>    </bean></beans>

5.编写请求处理的的处理器（Controller），并标识为处理器

package cn.hq.handler;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class HelloWorld {    @RequestMapping("/helloworld")    public String helloworld() {        System.out.println("helloworld");        return "success";    }}

6.编写视图

<%@ page language="java" contentType="text/html; charset=GB18030"    pageEncoding="GB18030"%><!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=GB18030"><title>Insert title here</title></head><body><h1>helloworld</h1>    <a href="helloworld">hello world</a></body></html>
