1.创建一个maven项目。

不会配置maven环境的可以看这里：maven的下载安装与配置环境变量！！！（全网最详细）_明天更新的博客-CSDN博客

2.引入依赖

<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.2.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>5.2.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>5.2.1.RELEASE</version>
        </dependency>
    </dependencies>

3.创建一个spring的配置文件

<?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="userEntity" class="com.entity.UserEntity"></bean>
</beans>

4.创建实体类

/*
 * Copyright (c) 2020, 2023,  All rights reserved.
 *
 */
package com.entity;

/**
 * <p>Project: spring-dome - UserEntity</p>
 * <p>Powered by scl On 2023-09-10 15:43:25</p>
 * <p>描述：<p>
 *
 * @author 孙臣龙 [1846080280@qq.com]
 * @version 1.0
 * @since 17
 */
public class UserEntity {
    public void show(){
        System.out.println("测试spring环境搭建！！！");
    }
}

5.获取Bean对象测试spring环境

/*
 * Copyright (c) 2020, 2023,  All rights reserved.
 *
 */

import com.entity.UserEntity;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * <p>Project: spring-dome - Test01</p>
 * <p>Powered by scl On 2023-09-10 15:47:23</p>
 * <p>描述：<p>
 *
 * @author 孙臣龙 [1846080280@qq.com]
 * @version 1.0
 * @since 17
 */
public class Test01 {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("spring.xml");
        UserEntity userEntity = classPathXmlApplicationContext.getBean("userEntity", UserEntity.class);
        System.out.println(userEntity);
        userEntity.show();
    }
}
