一.开发工具&运行环境

Eclipse + Tomcat6 + Jdk1.6 + Spring4.2

二.项目搭建

1.spring jar包准备：下载 spring-framework-4.2.2.RELEASE-dist.zip

2.new一个Dynamic Web Project (勾选自动生成web.xml). 命名 SpringMVC1

3.解压spring-framework-4.2.2.RELEASE-dist 把spring-framework-4.2.2.RELEASE\libs的所有jar包拷贝到工程WebContent\WEB-INF\lib 下

4.下载依赖包：commons-logging-1.1.3.jar ,因为页面用到JSTL,所以下载 jstl-1.2.jar 、standard-2.3.3.jar ,全部导入。

三. 开发

1.配置web.XML

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="SpringMVC1" version="2.5">

	<display-name>SpringMVC1</display-name>

	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>

	<servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
</web-app>

2.配置SpringMVC-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"
    xmlns:p="http://www.springframework.org/schema/p"    
    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-2.5.xsd     
           http://www.springframework.org/schema/context     
           http://www.springframework.org/schema/context/spring-context-2.5.xsd    
           http://www.springframework.org/schema/mvc     
           http://www.springframework.org/schema/mvc/spring-mvc-2.5.xsd"> 
     
    <!--BeanNameUrlHandlerMapping：表示将请求的URL和Bean名字映射，如URL为 “上下文/hello”，则Spring配置文件必须有一个名字为“/hello”的Bean，上下文默认忽略-->
	<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
	 
	<!-- HandlerAdapter ：InternalResourceViewResolver：用于支持Servlet、JSP视图解析； -->
	<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
	
	<!-- ViewResolver -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
	    <property name="prefix" value="/WEB-INF/jsp/"/>
	    <property name="suffix" value=".jsp"/>
	</bean>
	
    <!-- 处理器 -->
    <bean name="/index" class="com.niubaofeng.controller.IndexController"/> 
</beans>

3.新建 Index Controller

package com.niubaofeng.controller;

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 IndexController implements Controller{

	@Override
	public ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response) throws Exception {

	   ModelAndView mv = new ModelAndView();  
       mv.addObject("message", "Hello World!");  
       mv.setViewName("index");  
       return mv;
	}
}

4.新建index.jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!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=UTF-8">
<title>SpringMVC</title>
</head>
<body>
${message}
</body>
</html>

5.启动项目，浏览器输入地址：http://localhost:8080/SpringMVC1/index 页面输出" Hello World! "
