1.new一个maven project。勾上create a simple project,然后点击next
2.输入groupId 和ArtifactId, Version使用默认就可以,Packaging选war,其他可以不填,然后点击Finish
3.刚建好的工程,会报错,这是没有关系的,因为我们的web.xml还没有建好
4.右键工程,选择properties,点击Project Facets里面,去掉Dynamic Web Module勾选,Java选项上版本改为1.7,然后点击apply,再点击ok。
5.刚才去掉了Dynamic Web Module的勾选,是因为默认的web配置不能满足,我们要重新设置。所以,接下来,再次右键工程,选择properties,点击Project Facets里面,勾上Dynamic Web Module,并把版本改为2.5,点击下面的Further configuration available…,看到如下对话框:
如下所示:输入:src/main/webapp 并打勾,然后点击ok,在点击applay,点击ok
此时可以看见我们的目录结构如下,此时我们的工程已经搭建好
6.在webapp目录下新建一个index.jsp,工程或报错。
报错之后,我们需要新建一个tomacat服务器,在windows–>preference–>server–>runtime environment
中配置一个apache tomacat 服务器。配置好之后,右键工程,点击Build path,点击configure build path,
点击add libary
选择server time,然后一直next下
点击apply,ok。此时我们的工程就不再报错。
7.打开pom.xml文件,输入以下内容
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

8.打开web.xml,输入以下内容
<web-app id="WebApp_ID" 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>default.htmwelcome-file>

web-app>
9.在WEB-INF目录下新建一个文件view,在view中新建一个HelloWorld.jsp,内容如下
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title heretitle>
head>
<body>
<h1>message:${message}h1>
body>
html>
9.在WEB-INF目录下新建一个spring-servlet-mvc.xml,内容如下
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
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-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<context:annotation-config />
<context:component-scan base-package="com.springmvc.controller" >
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>
<mvc:annotation-driven/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"/>
<property name="suffix" value=".jsp" />
<property name="viewClass">
<value>org.springframework.web.servlet.view.InternalResourceViewvalue>
property>
<property name="order" value="1"/>
bean>
beans>
10.在src/main/java 目录下新建一个com.springmvc.controller包,在包里新建一个类Hello,内容如下
package com.springmvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping(value="/hello")
public class Hello {
@RequestMapping(value="/mvc",method=RequestMethod.GET)
public String HelloWorld(Model model){
model.addAttribute("message", "Hello world! spring mvc");
return "HelloWorld";
}
}
最后项目的目录如下图,项目中有红叉,这是不碍事的。
11.最后我们右键项目run as–>run on server,显示页面hello world.
然后我们在地址栏输入:http://localhost:8080/demo/hello/mvc。 见到如下页面,此时我们搭建springMVC环境并且写一个helloworld实例结束
