##### 创建项目名，设置项目路径 #####

##### 然后按照此目录依次创建文件（`applicationContext.xml`不用管，我们只需要用到`dispatcher-servlet.xml`） #####

#### `web.xml` 配置 ####

<?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"

        </context-param>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <servlet>
            <servlet-name>dispatcher</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>dispatcher</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
        //过滤

            <url-pattern>*.jpg</url-pattern>
        </servlet-mapping>
    </web-app>

#### `dispatcher-servlet.xml` 配置 ####

<?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"
           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.xsd">
    
        
        <context:component-scan base-package="com.springmvc"></context:component-scan>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="prefix" value="/WEB-INF/views/"></property>
            
            <property name="suffix" value=".html"></property>
        </bean>
    </beans>

#### 写一个简单的`controller` ####

@Controller
    public class helloworldHandler { 
        @RequestMapping("/helloworld")
        public  String helloworld(){ 
    
            return "success";
        }
    }

#### `success.html`内容 ####

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <h1>success page!</h1>
    </body>
    </html>

#### `index.html`内容 ####

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <a href="helloworld">helloWorld</a>
    </body>
    </html>
