開發環境：
Eclipse Mars.2 -----Version: Mars.2 Release (4.5.2) Build id: 20160218-0600
jdk1.8.0_73
Apache Tomcat 8.0.33
開發步驟：
1、新建maven project，選擇webapp
2、修改pom.xml，添加依賴jar，工程上右鍵Maven->Update Project下載依賴jar
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.1.2.RELEASE</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.1.2.RELEASE</version>
<scope>compile</scope>
</dependency>注：默認的maven庫訪問巨慢，可以考慮使用國內maven鏡像庫。拷貝\apache-maven-xxx\conf\settings.xml到C:\Users\用戶名\.m2下，mirrors字段下配置鏡像位置：
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>*</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>3、修改工程下的web.xml（\工程名\src\main\webapp\WEB-INF\）
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>如果碰到不能轉成3.0之類的錯誤，請修改\工程名\.settings\org.eclipse.wst.common.project.facet.core.xml
<installed facet="jst.web" version="3.0"/><?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:tx="http://www.springframework.org/schema/tx"
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
http://www.springframework.org/schema/tx

<!-- 配置掃描的包 -->
<context:component-scan base-package="com.java.mvn.springmvc.*" />
<!-- 註冊HandlerMapper、HandlerAdapter兩個映射類 -->
<mvc:annotation-driven />
<!-- 訪問靜態資源 -->
<mvc:default-servlet-handler />
<!-- 視圖解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>5、在WEB-INF下創建view文件夾，並在其中創建demo.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>首頁</title>
</head>
<body>
<h1>This is SpringMVC Demo</h1>
</body>
</html>6、創建DemoController類
package com.java.mvn.springmvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/demo")
public class DemoController {
@RequestMapping("/index")
public String index() {
return "demo";
}
}7、編譯工程（Project->Clean，之後再工程上右鍵Run As->Maven install），
右鍵Run As->Run on Server，用tomcat運行即可。
地址欄輸入http://localhost:8080/test_spring_mvc/demo/index
顯示This is SpringMVC Demo即爲成功部署。
