Question

我的bean上没有调用Destroy函数，即使我认为我已经正确配置了所有内容。请在下面找到相关代码：

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainApp {
    public static void main(String[] args) {
        AbstractApplicationContext  context = new ClassPathXmlApplicationContext("Beans.xml");

        // Create first instane of HelloWorld
        HelloWorld obj = (HelloWorld) context.getBean("helloWorldclass");

        obj.getMessage();
        obj.setMessage("Changed text");
        obj.getMessage();

        // Create another instance
        HelloWorld objB = (HelloWorld) context.getBean("helloWorldclass");
        objB.getMessage();

        context.registerShutdownHook();

    }
}

和

package com.tutorialspoint;

public class HelloWorld {

    // Field
    private String message;

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

    // Message getter
    public void getMessage() {
        if (message != null && !message.isEmpty()) {
            System.out.println("Your Message : " + message);
        } else {
            System.out.println("Your Message is empty");

        }
    }

    // Initialize
    public void init() {
        System.out.println("Bean is going through init.");
    }

    // destroy
    public void destroy() {
        System.out.println("Bean will destroy now.");
    }
}

和

<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-3.0.xsd">

   <bean id="helloWorldclass" class="com.tutorialspoint.HelloWorld"
    scope="prototype" init-method="init" destroy-method="destroy">
   </bean>

</beans>

我做错了什么？我没有看到来自destroy方法的消息。
