一、创建普通的maven项目

二、右键添加web支持

 三、pom.xml配置maven环境

 1 <!--导入依赖-->
 2     <dependencies>
 3         <dependency>
 4             <groupId>junit</groupId>
 5             <artifactId>junit</artifactId>
 6             <version>4.12</version>
 7         </dependency>
 8         <dependency>
 9             <groupId>org.springframework</groupId>
10             <artifactId>spring-webmvc</artifactId>
11             <version>5.1.9.RELEASE</version>
12         </dependency>
13         <dependency>
14             <groupId>javax.servlet</groupId>
15             <artifactId>servlet-api</artifactId>
16             <version>2.5</version>
17         </dependency>
18         <dependency>
19             <groupId>javax.servlet.jsp</groupId>
20             <artifactId>jsp-api</artifactId>
21             <version>2.2</version>
22         </dependency>
23         <dependency>
24             <groupId>javax.servlet</groupId>
25             <artifactId>jstl</artifactId>
26             <version>1.2</version>
27         </dependency>
28     </dependencies>

四、写一个spring-servlet.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4        xsi:schemaLocation="http://www.springframework.org/schema/beans
 5         http://www.springframework.org/schema/beans/spring-beans.xsd">
 6     <!--处理器映射器 BeanNameUrlHandlerMapping-->
 7     <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
 8     <!--处理器适配器 SimpleControllerHandlerAdapter-->
 9     <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
10     <!--视图解析器 InternalResourceViewResolver-->
11     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
12         <!---->
13         <property name="prefix" value="/WEB-INF/jsp/"/>
14         <property name="suffix" value=".jsp"/>
15     </bean>
16 </beans>

五、配置web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
 3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
 5          version="4.0">
 6     <!--配置DispatcherServlet 核心：前端控制器，请求分发器-->
 7     <servlet>
 8         <servlet-name>springmvc</servlet-name>
 9         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
10         <!--配置DispatcherServlet 绑定Spring的配置文件-->
11         <init-param>
12             <param-name>contextConfigLocation</param-name>
13             <param-value>classpath:springmvc-servlet.xml</param-value>
14         </init-param>
15         <!--启动级别 1 -->
16         <load-on-startup>1</load-on-startup>
17     </servlet>
18     <!-- / 和/ *的区别
19     / ：只能匹配所有的请求，不会匹配jsp页面
20     /* ：匹配请求和jsp页面
21     -->
22     <servlet-mapping>
23         <servlet-name>springmvc</servlet-name>
24         <url-pattern>/</url-pattern>
25     </servlet-mapping>
26 </web-app>
