Spring之bean二生命周期

上一博客主要学习了下bean的配置、注入、自定义属性编辑器，今天来熟悉bean的生命周期。在开发中生命周期是一个很常见的名词，基本每种编程语言都能找到与它关联的。关于bean的生命周期我在网上也找了好多，基本都差不多。这里我主要是想通过代码来验证，毕竟学的知识都是一样的，都是学的Java，最重要的是动手练习，这样印象更深。下面是它生命周期的描述，我们通过demo来进行验证。下图是它执行的顺序。

Spring之bean二生命周期

一、创建LiftCycle类实现BeanFactoryAware,BeanNameAware,InitializingBean,DisposableBean,ApplicationContextAware5个接口方法

package Cuiyw.Spring.Service;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.BeanFactoryAware;
import org.springframework.beans.factory.BeanNameAware;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;


public class LifeCycle  implements BeanFactoryAware,BeanNameAware,InitializingBean,DisposableBean,ApplicationContextAware{
    
    private String name;
    public String getName() {
        System.out.println("getName name="+name);
        return name;
    }
    public void setName(String name) {
         System.out.println("setName name="+name);
        this.name = name;
    }
    public void afterPropertiesSet() throws Exception {
        // TODO Auto-generated method stub
         System.out.println("InitializingBean.afterPropertiesSet()");
    }
    public void setBeanName(String arg0) {
        // TODO Auto-generated method stub
        System.out.println("BeanNameAware.setBeanName");

    }
    public void setBeanFactory(BeanFactory arg0) throws BeansException {
        // TODO Auto-generated method stub
        System.out.println("BeanFactoryAware.setBeanFactory");
    }
    public void destroy() throws Exception {
        // TODO Auto-generated method stub
        System.out.println("DisposableBean.destroy");
    }
    public void myInit() {
        System.out.println("【init-method】调用<bean>的init-method属性指定的初始化方法");
    }

    public void myDestory() {
        System.out.println("【destroy-method】调用<bean>的destroy-method属性指定的初始化方法");
    }
    public void setApplicationContext(ApplicationContext arg0) throws BeansException {
        // TODO Auto-generated method stub
         System.out.println("ApplicationContextAware.setApplicationContext");
    }
    
}
