IOC : defaulting init-method and destory-method

Bean.java:

package com.lnn.ioc;

import java.util.ArrayList;

import java.util.List;

public class Bean {

      private List<String> list = null;

      public void init() {

            list = new ArrayList<String>();

            list.add("One");

            list.add("Two");

            list.add("Three");

            System.out.println("Initialized.");

      }

      public void display() {

            for (String string : list) {

                  System.out.println(string);

            }

      }

      public void destroy() {

            list = null;

            System.out.println("Destroyed.");

      }

}

ioc.xml:

<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"

      default-init-method="init"

      default-destroy-method="destroy">

      <bean id="bean" class="com.lnn.ioc.Bean"/>

</beans>

Test.java:

package com.lnn.ioc;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

      public static void main(String[] args) {

            ApplicationContext context = new ClassPathXmlApplicationContext("ioc.xml");

            Bean bean = context.getBean("bean", Bean.class);

            bean.display();

      }

}
