项目目录如下（IDEA社区版好像无法识别webapp目录？原因见https://www.cnblogs.com/bityinjd/p/9284378.html）：
工具： IDEA
1、首先使用maven创建最简单的maven程序，groupId为com.admin，artifactId为SpringMVC, 然后修改pom.xml,添加jar包
<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.</modelVersion> <groupId>com.admin</groupId>
<artifactId>SpringMVC</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging> <properties>
<spring.version>4.3..RELEASE</spring.version>
</properties> <dependencies>
<!--Spring框架核心库 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<!-- Spring MVC -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<!-- Servlet核心包 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.</version>
<scope>provided</scope>
</dependency>
<!--JSP应用程序接口 -->
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency> </dependencies>
</project>
2、在src/main中创建webapp目录，创建index.jsp及WEB-INF目录，WEB-INF目录下创建web.xml
index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>最简单的web程序-首页</title>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>
web.xml
<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0"> <!--引导页-->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3、配置tomcat容器，（tomcat容器配置见https://www.cnblogs.com/best/p/5653916.html ）
启动web程序， 打开浏览器，输入http://localhost:8080,即可在浏览器中看到Hello World
4、添加一个简单的页面
在src/main/java中添加包com.admin.controller，新建类TestController
package com.admin.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
@RequestMapping("")
public class TestController { @RequestMapping("/test")
public String test() {
return "test";
}
}
在src/main/resources下新建servlet解析配置文件spring-servlet.xml
<?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-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd"> <!-- 自动扫描包，实现支持注解的IOC -->
<context:component-scan base-package="com.admin" /> <!-- Spring MVC不处理静态资源 -->
<mvc:default-servlet-handler /> <!-- 支持mvc注解驱动 -->
<mvc:annotation-driven enable-matrix-variables="true" /> <!-- 配置映射媒体类型的策略 -->
<bean
class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
<property name="removeSemicolonContent" value="false" />
</bean> <!-- 视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/views/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
在/WEB-INF/views/下新建test.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>test</title>
</head>
<body>
<h1>测试</h1>
</body>
</html>
在web.xml中添加对视图解析器，修改后的文件为：
<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0"> <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*:springmvc-servlet.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> <!--引导页-->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
5、浏览器下输入http://localhost:8080/test
即可看到test.jsp页面
