1、pom.xml依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.0.6.RELEASE</version>
</dependency>

2、实体类

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Person {
    private String name;
    private int age;
}

3、src\main\resources\beans.xml

<?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="person" class="com.it.vo.Person">
        <property name="name" value="刘长"></property>
        <property name="age" value="23"></property>
    </bean>
</beans>

4、测试类

import com.it.vo.Person;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class PersonTest {
    public static void main(String [] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
        Person person = (Person)applicationContext.getBean("person");
        System.out.println(person);
    }
}

//结果：Person(name=刘长, age=23)
