1、在eclipse中创建一个动态的webapp

2、WEB-INF/lib导入需要的jar文件

spring.jar (from spring-framework-2.5/dist)

spring-webmvc.jar(from spring-framework-2.5/dist/modules)

commons-logging.jar (from spring-framework-2.5/lib/jakarta-commons)

3、配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee          http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><!-- 映射的配置 --><servlet><servlet-name>springapp</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><!-- 將所有以*.htm結尾的请求交给 org.springframework.web.servlet.DispatcherServlet--><servlet-mapping><servlet-name>springapp</servlet-name><url-pattern>*.htm</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

4.springapp-servlet.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">  <!-- 配置DispatcherServlet -->  <!-- /hello.htm的请求交给 springapp.web.HelloController-->  <bean name="/hello.htm" class="springapp.web.HelloController"/></beans>

5、创建一个控制器

package springapp.web;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;public class HelloController implements Controller {@Overridepublic ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response) throws Exception {return new ModelAndView("hello.jsp");}}

6、然后在WebContent目录下创建一个hello.jsp

<%@ page language="java" contentType="text/html; charset=gbk"pageEncoding="gbk"%><!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=gbk"><title>Insert title here</title></head><body><h1>Hello - Spring Application</h1><p>Greetings.</p></body></html>

6、启动tomcat在浏览器中输入：http://localhost:8080/springmvc/hello.htm即可
