一般写Spring的文章，会先说一下，IOC容器、DI等概念性的内容。但是由于是个人的笔记，就直入主题。就是要熟悉Spring的XML是怎么配的。[https://gitee.com/gao_xi/spring-demo1/tree/master/](https://gitee.com/gao_xi/spring-demo1/tree/master/)

1.开发环境

JDK1.8
Maven3.6
IDEA2019.3

2.搭建步骤

2.1创建工程

2.2xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <bean id="book" class="com.gao.Book"></bean>
</beans>

2.3代码编写

/**
 * @author GaoXi
 * @date 2021/8/13 19:31
 */
public class Book {
    public void sayHello() {
        System.out.println("Hello Spring5");
    }
}
/**
 * @author GaoXi
 * @date 2021/8/13 19:33
 */
public class Starter {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("config.xml");
        Book book = applicationContext.getBean("book", Book.class);
        book.sayHello();
    }
}

3.如何手动下载Spring的相关jar包
