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:
Main.java
