spring入门之环境搭建！！！

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

        
            org.springframework
            spring-core
            5.2.1.RELEASE
        
        
            org.springframework
            spring-beans
            5.2.1.RELEASE
        
        
            org.springframework
            spring-context
            5.2.1.RELEASE
        
        
            org.springframework
            spring-context-support
            5.2.1.RELEASE
        
    

3.创建一个spring的配置文件

 4.创建实体类

 */
package com.entity;

/**
 * 
Project: spring-dome - UserEntity
 * 
Powered by scl On 2023-09-10 15:43:25
 * 
描述：

 *
 * @author 孙臣龙 [[email protected]]
 * @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

/*

 *
 */

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

/**
 * 
Project: spring-dome - Test01
 * 
Powered by scl On 2023-09-10 15:47:23
 * 
描述：

 *
 * @author 孙臣龙 [[email protected]]
 * @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();
    }
}

 6.测试结果
