1.创建dynamic web Project项目  
2.加入jar包

commons-logging-1.1.1.jar
    spring-aop-4.0.4.RELEASE.jar
    spring-beans-4.0.4.RELEASE.jar
    spring-context-4.0.4.RELEASE.jar
    spring-core-4.0.4.RELEASE.jar
    spring-expression-4.0.4.RELEASE.jar
    spring-web-4.0.4.RELEASE.jar
    spring-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">
    
        
    
        <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">
        
        <context:component-scan base-package="cn.hq.handler"></context:component-scan>
    
        
        <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;
    
    @Controller
    public 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>
