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

2.5.1下面我只贴出重要的配置文件，其他的你们自己写或者直接下载我的源码
