Demo的結構：
-
準備jar包，上面項目結構的jar 包請自行準備；
-
創建resources根目錄，在裏面創建spring mvc 的配置文件：springmvc.xml
根目錄創建方法：resources 目錄右鍵：
![在這裏插入圖片描述]()
-
springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!--1配置類掃描器-->
<context:component-scan base-package="com.hao.springmvc"/>
<!--2.配置註解驅動，可以使用springmvc的註解-->
<mvc:annotation-driven/>
<!--3.配置視圖解析器,解析路徑“/”不能丟-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
- 配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<!--配置前端控制器 （分發處理各種請求）-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--配置讀取核心配置文件springmvc.xml-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!--代表當前servlet（DispatcherServlet）對象，隨tomcat啓動，創建servlet對象
1代表優先級，必須式正整數，最小就是1-->
<load-on-startup>1</load-on-startup>
</servlet>
<!--配置servlet映射路徑<url-pattern>/</url-pattern>"/"代表攔截所有路徑-->
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
