参考：史上最详细的IDEA优雅整合Maven+SSM框架（详细思路+附带源码）_宜春-优快云博客_ssm框架idea整合代码

spring+struts2+ibatis和spring+springmvc+ibatis的区别是把struts2换成springmvc

在Idea 整合maven+ssi(spring+struts2+ibatis)_allensandy的博客-优快云博客的基础上进行改造，主要把struts2​​​​​​​换成springmvc主要步骤有

1、pom.xml

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

       <!-- 上传组件包 -->
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.3.1</version>
        </dependency>

后面springmvc如果要配置文件上传要加入上传的jar包

2、web.xml

mvc框架部分把struts换成springmvc：

 代码：

 <!-- 2.springmvc的前端控制器 -->
    <servlet>
        <servlet-name>comqing-manager</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>comqing-manager</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

3、spring/springmvc.xml

<?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:p="http://www.springframework.org/schema/p"
       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.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
    <context:component-scan base-package="com.steven.controller" />
    <!-- 默认的注解映射的支持 -->
    <mvc:annotation-driven />
    <!-- 视图解析 -->
    <bean
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
    <!-- 资源映射 -->
    <mvc:resources location="/WEB-INF/css/" mapping="/css/**"/>
    <mvc:resources location="/WEB-INF/js/" mapping="/js/**"/>

    <!-- 定义文件上传解析器 -->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 设定默认编码 -->
        <property name="defaultEncoding" value="UTF-8"></property>
        <!-- 设定文件上传的最大值5MB，5*1024*1024 -->
        <property name="maxUploadSize" value="5242880"></property>
    </bean>
</beans>

4、controller

package com.steven.controller;

import com.steven.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

/**
 * @author steven
 * @date 2021/10/20
 */
@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/login")
    @ResponseBody
    public String login() {
        String name = userService.getNameById(1);
        return "WelCome login: " + name;
    }

    @RequestMapping(value = "/mdv")
    public ModelAndView mdv() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("test");
        mav.addObject("msg", "hello kaka!");
        return mav;
    }
}

5、其他代码

webapp/WEB-INF/jsp/test.jsp

<%--

到此整合完毕
