尚硅谷Spring5框架教程(idea版) https://www.bilibili.com/video/BV1Vf4y127N5?p=1

使用快速开发模板

user类的内容

package com.atguigu.spring5;
public class User {
    public void add(){
        System.out.println("add~~~~~");
    }
}

实现一个简单的maven的spring项目，要导入的几个依赖

一共五个包，主要有四个核心依赖 beans,core,context,expression,以及一个关于 日志的jar包，

关于依赖的版本可以在mvn的官网查看依赖的语句

步骤1.点击查找到的mvn仓库

步骤2.点击spring.context

步骤3.选择想要下载的依赖的版本

步骤4.查看依赖的代码并加入到pom.xml中
