尚硅谷Spring5框架教程(idea版) https://www.bilibili.com/video/BV1Vf4y127N5?p=1
1.使用Maven创建项目
使用快速开发模板
2.目录结构如图
3.定义user类
user类的内容
package com.atguigu.spring5;
public class User {
public void add(){
System.out.println("add~~~~~");
}
}
4.定义bean1.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="user" class="com.atguigu.spring5.User"></bean>
</beans>
5.pom.xml 文件中下载对应依赖
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

6.TestSpring类中的内容
package com.atguigu.spring5.testdemo;
import com.atguigu.spring5.User;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestSpring {
@Test
public void test() {
//1 加载spring配置文件
ApplicationContext context=
new ClassPathXmlApplicationContext("bean1.xml");
//2 获取配置的对象
User user=context.getBean("user", User.class);
System.out.println(user);
user.add();
}
}
运行结果
