一：导入包
通过maven创建web app
这里写图片描述

pom.xml如下：

<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.walee</groupId>    <artifactId>DemoSpringMVC</artifactId>    <packaging>war</packaging>    <version>0.0.1-SNAPSHOT</version>    <name>DemoSpringMVC Maven Webapp</name>    <url>http://maven.apache.org</url>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>3.8.1</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>4.3.5.RELEASE</version>        </dependency>        <dependency>            <groupId>commons-lang</groupId>            <artifactId>commons-lang</artifactId>            <version>2.6</version>        </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jstl</artifactId>            <version>1.2</version>            <scope>runtime</scope>        </dependency>    </dependencies>    <build>        <finalName>DemoSpringMVC</finalName>    </build></project>

二：web.xml中配置DispatcherServlet
web.xml配置如下：

<!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>  <display-name>Archetype Created Web Application</display-name>  <servlet>    <servlet-name>mvc-dispatcher</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <!--可以使用默认的，适用默认的就不用配置了，    默认：/WEB-INF/[servlet-name]-servlet.xml    -->    <init-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/mvc-config/springmvcConfig.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>mvc-dispatcher</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping></web-app>

三：配置SpringMVC的配置文件

springmvcConfig.xml如下：

<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.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc.xsd">     <!-- 激活注解 -->    <context:annotation-config />   <!-- 自动扫描controller -->  <context:component-scan base-package="com.walee.control">  </context:component-scan>  <mvc:annotation-driven/>  <!--视图解释器 -->  <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>    <property name="prefix" value="/WEB-INF/jsp/"/>    <property name="suffix" value=".jsp"/>  </bean></beans>

四：编写Controller

package com.walee.control;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping("/hello")public class HelloController {    @RequestMapping("/mvc")    public String helloMvc(){        return "home";    }}

五：编写视图

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"    pageEncoding="ISO-8859-1"%><!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=ISO-8859-1"><title>Insert title here</title></head><body><h1>Hello SpringMVC</h1></body></html>

六：访问
部署到tomcat，
URL:http://localhost：8080/DemoSpringMVC/hello/mvc
