一、导入SpringMVC环境所需基础Jar包

下载 http://pan.baidu.com/s/1jGEAZ9G

spring-aop-3.2.0.RELEASE.jarspring-aspects-3.2.0.RELEASE.jarspring-beans-3.2.0.RELEASE.jarspring-context-3.2.0.RELEASE.jarspring-context-support-3.2.0.RELEASE.jarspring-core-3.2.0.RELEASE.jarspring-expression-3.2.0.RELEASE.jarspring-instrument-3.2.0.RELEASE.jarspring-instrument-tomcat-3.2.0.RELEASE.jarspring-jdbc-3.2.0.RELEASE.jarspring-jms-3.2.0.RELEASE.jarspring-orm-3.2.0.RELEASE.jarspring-oxm-3.2.0.RELEASE.jarspring-test-3.2.0.RELEASE.jarspring-tx-3.2.0.RELEASE.jarspring-web-3.2.0.RELEASE.jarspring-webmvc-3.2.0.RELEASE.jarspring-webmvc-portlet-3.2.0.RELEASE.jar

commons-logging.jar    //注:日志jar包

二、编辑web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.html</welcome-file>  </welcome-file-list>    <servlet>  <servlet-name>springMVC</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <init-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath*:com/llqqww/config/springMVC-servlet.xml</param-value>  </init-param>  <load-on-startup>1</load-on-startup>  <!--启动顺序,tomcat一启动就初始化SprinMVC-->  </servlet>    <servlet-mapping>  <servlet-name>springMVC</servlet-name>  <url-pattern>/</url-pattern>  </servlet-mapping></web-app>

注：

init-param 中设置其他配置文件路径，没有init-param默认是在/WEB-INF目录下所有*-servlet.xml文件

本文配置文件springMVC-servlet.xml在src的com.llqqww.config包内

spring配置文件名需与web.xml中的<servlet-name></servlet-name>中一致

三、添加springMVC-servlet.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"   xmlns:context="http://www.springframework.org/schema/context"   xmlns:p="http://www.springframework.org/schema/p"   xmlns:mvc="http://www.springframework.org/schema/mvc"   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-3.0.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-3.0.xsd"><bean name="/hi/helloworld" class="com.llqqww.controller.HelloWorldController" /><bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean> </beans>

注：

/hi/helloworld是访问Controller的URL路径、class是该URL访问的Controller

prefix 若是'/',则是用户可直接访问WebRoot下的jsp文件、若是"/WEB-INF/jsp/"，则只能通过Controller映射访问jsp文件(不能直接访问"/WEB-INF"目录下文件)

四、编写Controller控制器

新建com.llqqww.controller包,创建类HelloWorldController 继承Controller 类，实现handleRequest方法

package com.llqqww.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 HelloWorldController implements Controller {public ModelAndView handleRequest(HttpServletRequest arg0,HttpServletResponse arg1) throws Exception {System.out.println("-------Welocome-----");return new ModelAndView("/welcome");}}

五、在WebRoot目录下建立View文件

welcome.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%><!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>Insert title here</title></head><body>Welcome~</body></html>

六、访问Controller控制器

启动tomcat部署项目,浏览器访问如:localhost:8080/hi/helloworld 则会看到welcome.jsp文件中的"Welcome~"信息
