spring 中的IOC 操作 Bean 管理（bean 生命周期）_spring ioc有管理bean的销毁吗

public class Orders {
    //无参数构造
    public Orders() {
        System.out.println("第一步 执行无参数构造创建 bean 实例");
    }
    private String oname;
    public void setOname(String oname) {
        this.oname = oname;
        System.out.println("第二步 调用 set 方法设置属性值");

 <bean id="orders" class="net.cybclass.sp.domain.Orders" init-method="initMethod" destroy-method="destroyMethod">
    <property name="oname" value="手机"></property>

public class app {

        System.out.println(orders);
        //手动让 bean 实例销毁
        context.close();
    }
}

 运行：

package net.cybclass.sp.domain;
 
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
 
/**
 * @author: wangxiaobo
 * @create: 2020-10-04 19:26
 **/
public class MyBeanPost  implements BeanPostProcessor {
    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName)
            throws BeansException {
        System.out.println("在初始化之前执行的方法");
        return bean;
    }
    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName)
            throws BeansException {
        System.out.println("在初始化之后执行的方法");
        return bean;
    }
}

<!--配置后置处理器-->
    <bean id="myBeanPost" class="net.cybclass.sp.domain.MyBeanPost"></bean>
