init和destory方法

4.1.新建一个Demo2的实体类;

package com.eduask.entity;

//新建一个Demo2的实体类;

public class Demo2 {

public void init(){

System.out.println("这是init方法");

}

public void destory(){

System.out.println("调用cx.close方法之后");

System.out.println("这是destory方法");

}

}

4.2新建一个TestDemo2的测试类

package com.eduask.entity;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestDemo2 {

public static void main(String[] args) {

ClassPathXmlApplicationContext cx=new ClassPathXmlApplicationContext("demo2.xml");

Demo2 demo2=(Demo2) cx.getBean("Demo2");

//只有当执行cx.close方法时，Demo2中的destory方法才会被执行;

cx.close();

}

}

4.3 新建一个demo2.xml的配置文件

<?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="Demo2" class="com.eduask.entity.Demo2" init-method="init" destroy-method="destory">

</bean>

</beans>
