> 第一步：创建一个简单的spring bean

public class HelloWord {
    
        private String name;
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    }

>  第二步：配置spring bean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"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:util="http://www.springframework.org/schema/util"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">
        
        <bean id="helloWord" class="com.spring.beans.HelloWord">
            <property name="name" value="HelloWord"></property>
        </bean>
        
    </beans>

>  第三步：执行代码，获取bean内容

public class SpringTest {
    
        public static void main(String[] args) {
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-config.xml");
            HelloWord helloWord = (HelloWord) applicationContext.getBean(HelloWord.class);
            System.out.println(helloWord.toString());
        }
    }

> 输出内容：HelloWord
