很感谢拓盛的汤老师！

1.创建一个简单的Maven工程


这时候出现错误，没关系是因为缺少了web.xml文件


2.配置web.xml文件

2.1在webapp下面创建一个文件夹，叫做WEB-INF


2.2在/WEB-INF的文件夹下创建web.xml文件


如下图所示





2.3 配置web.xml文件


<?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"
	version="3.0">

	<!-- spring框架必须定义ContextLoaderListener，在启动Web容器时，自动装配Spring applicationContext.xml的配置信息 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<context-param>
		<!-- 指定Spring上下文配置文件 -->
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:applicationContext.xml</param-value>
	</context-param>
	<context-param>
		<param-name>spring.profiles.active</param-name>
		<param-value>production</param-value>
	</context-param>

	<servlet>
		<servlet-name>Dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<!-- 指定SpringMVC配置文件 -->
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath*:springmvc.xml</param-value>
		</init-param>
	</servlet>

	<servlet-mapping>
		<!-- 指定请求的后缀，可以随意写，这里用.html作为请求后缀 -->
		<servlet-name>Dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

	<!-- 编码格式为UTF-8 -->
	<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>

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
	</welcome-file-list>

</web-app>


2.4 配置pom.xml文件
