销毁方法在弹簧框架中不起作用

编辑：这个问题与何时调用销毁方法不同，因为我正在正确调用，并且我的Bean正在变得令人沮丧，正如您从日志中看到的那样。我的问题是春天没有调用我的方法。在问这里之前，我已经检查了这个问题。context.registerShutdownHook

我正在使用spring框架在我的应用程序中配置优雅的销毁。当我运行程序时，它不会调用bean中指定的destory方法.xml。请帮帮我做错了什么。

这里是SSCCE

豆.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="helloworld" class="com.hello.pojo.HelloWorld" 
          scope="prototype" init-method="init" destroy-method="destroy">
    </bean>

</beans>

你好词.java

package com.hello.pojo;

public class HelloWorld {


    private String message;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public void init(){
        System.out.println("Bean initializating is in progress");
    }

    public void printMessage(){
        System.out.println("Your message: "+getMessage());
    }
    public void destroy(){
        System.out.println("Bean is being destroyed");
    }

}

主应用程序.java

package com.main;

import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.hello.pojo.HelloWorld;


public class MainApp {

    public static void main(String[]args){
        AbstractApplicationContext context = new ClassPathXmlApplicationContext("Bean.xml");
        HelloWorld objA = (HelloWorld) context.getBean("helloworld");
        objA.setMessage("I am Object A");
        objA.printMessage();
        context.registerShutdownHook();
    }

}

输出

修正：我试图关闭上下文，但没有一个起作用。closeregisterShutdownHook()
