·Spring Web MVC 轻量级Web框架，帮助简化开发
创建maven工程
1、添加jar包
<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.zzxtit</groupId>
<artifactId>springMVC.helloworld</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>springMVC.helloworld Maven Webapp</name>
<url>http://maven.apache.org</url>
<properties>
<junit.version>4.12</junit.version>

<version>${spring.version}</version>
</dependency>
</dependencies>
<build>
<finalName>springMVC.helloworld</finalName>
</build>
</project>
2、配置文件
<?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:util="http://www.springframework.org/schema/util"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd ">
<context:component-scan base-package="com.zzxt（此处为applicationContext-mvc.xml所在包名）"></context:component-scan>
</beans>
3、配置web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/applicationContext-mvc.xml</param-value>
</init-param>
</servlet>
<!--
/ :拦截所有的请求(包含静态文件、不包含jsp)
*.action *.do (开一个后台系统的推荐配置)
/* ：拦截所有的请求(包含静态文件、jsp )
-->
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
4、Controller
package com.zzxt;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller（表明是一个控制层）
public class HelloWorldController {
private Log log = LogFactory.getLog(HelloWorldController.class);
@RequestMapping("sayHello")
public ModelAndView（以ModelAndView的形式返回） sayHello(){
ModelAndView mav =new ModelAndView();（返回ModelAndView，新建一个ModelAndView对象）
mav.setViewName("views/success.jsp");（返回视图）
log.info("--------spring MVC hello world!");
return mav;
}
}
