1.以ApplocationContext上下文单例模式装配bean为例，深入探讨bean的生命周期：

（1）.生命周期图：

（2）.具体事例：

person类实现BeanNameAware,BeanFactoryAware接口

public class Person implements BeanNameAware ,BeanFactoryAware{ private String name; public Person(){ System.out.println("调用构造器为属性值初始化"); } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public void setBeanName(String arg0) { // TODO Auto-generated method stub System.out.println("获取beanName id值"+" "+arg0); } @Override public void setBeanFactory(BeanFactory arg0) throws BeansException { // TODO Auto-generated method stub System.out.println("获取BeanFactory" +" "+arg0); }}public class MyBeanPostProcessor implements BeanPostProcessor{ @Override public Object postProcessAfterInitialization(Object arg0, String arg1) throws BeansException { // TODO Auto-generated method stub System.out.println("调用postProcessAfterInitialization"); return arg0; } @Override public Object postProcessBeforeInitialization(Object arg0, String arg1) throws BeansException { // TODO Auto-generated method stub System.out.println("调用postProcessBeforeInitialization"); return arg0; }}

ApplicationContext.xml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的配置文件 --><bean id="person" class="org.jingdong.bean.life.Person"><property name="name" value="grl"></property></bean><bean id="myBeanPostProcessor" class="org.jingdong.bean.life.MyBeanPostProcessor"></bean></beans>

Main.java

public class Main { public static void main(String[] args) { // 创建IOC容器 ApplicationContext ac = new ClassPathXmlApplicationContext("org/jingdong/bean/life/applicationContext.xml"); //从容器中获取bean实例 Person person = (Person) ac.getBean("person"); //使用bean System.out.println(person.getName()); }}
