Spring Bean的生命周期（非常详细）(三)
接口方法、实例化Bean之后调用
28 @Override
29 public Object postProcessAfterInitialization(Object bean, String beanName)
30 throws BeansException {
31 System.out
32 .println("InstantiationAwareBeanPostProcessor调用postProcessAfterInitialization方法");
33 return bean;
34 }
35
36 // 接口方法、设置某个属性时调用
37 @Override
38 public PropertyValues postProcessPropertyValues(PropertyValues pvs,
39 PropertyDescriptor[] pds, Object bean, String beanName)
40 throws BeansException {
41 System.out
42 .println("InstantiationAwareBeanPostProcessor调用postProcessPropertyValues方法");
43 return pvs;
44 }
45 }
复制代码
这个有3个方法，其中第二个方法postProcessAfterInitialization就是重写了BeanPostProcessor的方法。第三个方法postProcessPropertyValues用来操作属性，返回值也应该是PropertyValues对象。
4、演示工厂后处理器接口方法，如下：
复制代码
1 package springBeanTest;
2
3 import org.springframework.beans.BeansException;
4 import org.springframework.beans.factory.config.BeanDefinition;
5 import org.springframework.beans.factory.config.BeanFactoryPostProcessor;
6 import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
7
8 public class MyBeanFactoryPostProcessor implements BeanFactoryPostProcessor {
9
10 public MyBeanFactoryPostProcessor() {
11 super();
12 System.out.println("这是BeanFactoryPostProcessor实现类构造器！！");
13 }
14
15 @Override
16 public void postProcessBeanFactory(ConfigurableListableBeanFactory arg0)
17 throws BeansException {
18 System.out
19 .println("BeanFactoryPostProcessor调用postProcessBeanFactory方法");
20 BeanDefinition bd = arg0.getBeanDefinition("person");
21 bd.getPropertyValues().addPropertyValue("phone", "110");
22 }
23
复制代码
5、配置文件如下beans.xml，很简单，使用ApplicationContext,处理器不用手动注册：
复制代码
< xml version="1.0" encoding="UTF-8" >
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
destroy-method="myDestory" scope="singleton" p:name="张三" p:address="广州"
p:phone="15900000000" />
复制代码
6、下面测试一下：
复制代码
1 package springBeanTest;
2
3 import org.springframework.context.ApplicationContext;
4 import org.springframework.context.support.ClassPathXmlApplicationContext;
5
6 public class BeanLifeCycle {
7
8 public static void main(String[] args) {
9
10 System.out.println("现在开始初始化容器");
11
12 ApplicationContext factory = new ClassPathXmlApplicationContext("springBeanTest/beans.xml");
13 System.out.println("容器初始化成功");
14 //得到Preson，并使用
15 Person person = factory.getBean("person",Person.class);
16 System.out.println(person);
17
18 System.out.println("现
