Spring MVC作为SpringFrameWork的产品，自诞生之日，就受到广泛开发者的关注，如今Spring MVC在Java中的发展可谓是蒸蒸日上，如今如果再有开发者说，不了解Spring MVC，或许就被人笑掉大牙。煽情的话就不说了，先告诉大家如何搭建Spring MVC开发环境。

（一）工作环境准备：

JDK 1.7

Eclipse Kepler

Apache Tomcat 8.0

（二）在Eclipse中新建Maven工程，在Archetype类型中，选择“maven-archetype-webapp”。

（三）配置pom.xml。

<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/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.favccxx.favsoft</groupId>
  <artifactId>favspringmvcrestful</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>favspringmvcrestful Maven Webapp</name>
  <url>http://maven.apache.org</url>
  
   <properties>
  	<spring.version>4.1.1.RELEASE</spring.version>
  </properties>
  
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    
    <dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-core</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-beans</artifactId>
		<version>${spring.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-context</artifactId>
		<version>${spring.version}</version>
	</dependency>
	
	<dependency>
		<groupId>jstl</groupId>
		<artifactId>jstl</artifactId>
		<version>1.2</version>
	</dependency>
	<dependency>
		<groupId>taglibs</groupId>
		<artifactId>standard</artifactId>
		<version>1.1.2</version>
	</dependency>
    
  </dependencies>
  <build>
    <finalName>favspringmvcrestful</finalName>
  </build>
</project>

（四）在WEB-INF/web.xml，配置Spring MVC转发。

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	<display-name>favspringmvcrestful</display-name>

	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<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*:spring-context.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springMVC</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

（五）在resources目录下，创建spring-context.xml，支持注解，页面路径解析等。

<?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: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-4.1.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
		
	<context:component-scan base-package="com.favccxx.favsoft.favjson.controller"></context:component-scan>
	
	<mvc:annotation-driven></mvc:annotation-driven>
	
    <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/views" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

（六）新建HelloController类，使用注解完成Spring MVC类的调用。

package com.favccxx.favsoft.favjson.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloController {
	
	@RequestMapping("/greeting")
    public ModelAndView greeting(@RequestParam(value="name", defaultValue="World") String name) {
		 System.out.println("Hello " + name);
		 Map<String, Object> map = new HashMap<String, Object>();
		 map.put("userName", name);
		 return new ModelAndView("/hello",map);
    }
	 
}

（七）创建/WEB-INF/views/hello.jsp，用来展现数据。

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello</title>
</head>
<body>
	你好，${userName }
</body>
</html>

（八）在浏览器中，输入访问的URL：http://localhost:8080/favspringmvcrestful/greeting?name=%E7%BE%8E%E5%A5%B3，运行效果如下：
