Webを作成します.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
    <!-- Spring  Servlet   -->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

springmvcを作成する.xml
springmvc.xmlは上のclasspath:springmvcとxmlマッチング

<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
    <!--          -->
    <context:component-scan base-package="com.sanchan.server.controller"></context:component-scan>
    <!--          ： Controller               -->
    <bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>

#作成Controller srcでcomを作成する.sanchan.server.controller.HelloWorld

package com.sanchan.server.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

//     Spring    ，      
@Controller
public class HelloWorld {
    /** * 1、 @RequestMapping      URL * 2、                     ，  org.springframework.web.servlet.view. * InternalResourceViewResolver     ，      ： * prefix【 springmvc.xml    prefix 】+  return    +suffix【 springmvc.xml    suffix 】 * @return */
    @RequestMapping("/helloworld")
    public String hello() {
        System.out.print("hello world");
        return "success";
    }
}

WEB-INFの下に/views/successを作成する.jsp
これで簡単なspring mvcが完成しました
