作者各必备工具的版本如下：步骤 1使用 Java EE – Eclipse 新建一 Dynamic Web Project。
步骤 2输入项目名 bdp。
Target Runtime 选 Apache Tomcat 7.0(不要选 Apache Tomcat 6.0，7 以后才支持 Servlet 3.0)。点击 Next > 按钮。步骤 3编辑默认的 Source folders。默认的 Source folders 配置如下：
删除默认的，增加以下四个并修改默认的输出目录为 WebContent\WEB-INF\classes:
点击 Next > 按钮。步骤 4Configure web module settings 对话框勾选 Generate web.xml deployment descriptor 选项：
点击 Finish 按钮。步骤 5将新建好的项目转换为 Maven 项目以管理项目依赖。Package Explorer 视图下右击 bdp 项目名 -> Configure -> Convert to Maven project。步骤 6添加以下 jar 依赖到项目：
我的 pom.xml 文件如下：<project xmlns="" xmlns:xsi=""xsi:schemaLocation=" http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>bdp</groupId><artifactId>bdp</artifactId><version>1.0.0</version><packaging>war</packaging><name>bdp</name><description>Basic Data Platform</description><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><spring.version>4.2.0.RELEASE</spring.version></properties><dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><dependency><groupId>commons-logging</groupId><artifactId>commons-logging</artifactId><version>1.1.3</version></dependency></dependencies><build><plugins><plugin><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration><source>1.7</source><target>1.7</target></configuration></plugin><plugin><artifactId>maven-war-plugin</artifactId><version>2.4</version><configuration><warSourceDirectory>WebContent</warSourceDirectory><failOnMissingWebXml>false</failOnMissingWebXml></configuration></plugin></plugins></build></project>步骤 7在 src/main/resources 目录下创建 Spring MVC Bean 配置文件 bdpmvc-servlet.xml。<?xml version="1.0" encoding="UTF-8"?><beans xmlns=""xmlns:xsi="" xmlns:p=""xmlns:context=""xsi:schemaLocation=" http://www.springframework.org/schema/context "> <context:component-scan base-package="com.defonds.bdp.city.controller" /> <bean id="viewResolver"class="org.springframework.web.servlet.view.UrlBasedViewResolver"><property name="viewClass"value="org.springframework.web.servlet.view.JstlView" /><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean></beans>以上 bdpmvc-servlet.xml 配置文件里，我们定义了一个 <context:component-scan> 标签。这一配置将使 Spring 去加载 com.defonds.bdp.city.controller 及其子包下的所有 @Component、@Controller、@Service、@Repository 等注解了的类。此外，我们还定义了一个 viewResolver bean，它将给 ModelAndView 的视图加上 /WEB-INF/jsp/ 前缀以及 .jsp 后缀。比如我们的 CityController 类里返回了一个视图名为 welcome 的 ModelAndView 对象，它将被解析至路径 /WEB-INF/jsp/welcome.jsp。步骤 8将 Spring MVC 映射到 /WEB-INF/web.xml 文件。<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="" xmlns="" xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>bdp</display-name> <welcome-file-list><welcome-file>index.jsp</welcome-file> </welcome-file-list><servlet><servlet-name>bdpmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/classes/bdpmvc-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>bdpmvc</servlet-name><url-pattern>*.json</url-pattern><url-pattern>*.html</url-pattern></servlet-mapping></web-app>DispatcherServlet 初始化的时候将会读取 /WEB-INF/classes/ 下的 bdpmvc-servlet.xml 文件。步骤 9创建 Controller 类。包：com.defonds.bdp.city.controller类名：CityController.java/** * File Name：CityController.java * * Copyright Defonds Corporation 2015 * All Rights Reserved * */package com.defonds.bdp.city.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;/** * * Project Name：bdp * Type Name：CityController * Type Description： * Author：Defonds * Create Date：2015-8-27 * @version * */@Controller@RequestMapping("/city")public class CityController {@RequestMapping("/welcome")public ModelAndView helloWorld() {String message = "<br><div>"+ "<h3>********** Hello World, Spring MVC Tutorial</h3>This message is coming from CityController.java **********</div><br><br>";return new ModelAndView("welcome", "message", message);}}步骤 10
创建 /WebContent/index.jsp 和 /WebContent/WEB-INF/jsp/welcome.jsp 视图文件。
始终调整好自己观风景的心态，
