《读spring源码》1根据beanxml探索

简单讲解，本是怎么被IOC加载到内存的实例如下：

运行效果如下:

代码如下：

package com.enjoy.cap1;

import lombok.Data;

@Data
public class Person {
    private String name;
    private Integer age;
}

package com.enjoy.cap1;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ClassPathBeanDefinitionScanner;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainTest {

    private static ClassPathXmlApplicationContext classPathXmlApplicationContext;


    public static void main(String args[]){
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");

        Person person = (Person) applicationContext.getBean("person");
        System.out.println(person.toString());
    }
}

<?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.enjoy.cap1.Person">
        <property name="name" value="wyl"></property>
        <property name="age" value="19"></property>
    </bean>

</beans>
