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">
    <!--自己添加的代码-->
    <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
