Spring Bean的生命周期（非常详细）(二)
71 System.out.println("【BeanNameAware接口】调用BeanNameAware.setBeanName()");
72 this.beanName = arg0;
73 }
74
75 // 这是InitializingBean接口方法
76 @Override
77 public void afterPropertiesSet() throws Exception {
78 System.out
79 .println("【InitializingBean接口】调用InitializingBean.afterPropertiesSet()");
80 }
81
82 // 这是DiposibleBean接口方法
83 @Override
84 public void destroy() throws Exception {
85 System.out.println("【DiposibleBean接口】调用DiposibleBean.destory()");
86 }
87
88 // 通过的init-method属性指定的初始化方法
89 public void myInit() {
90 System.out.println("【init-method】调用的init-method属性指定的初始化方法");
91 }
92
93 // 通过的destroy-method属性指定的初始化方法
94 public void myDestory() {
95 System.out.println("【destroy-method】调用的destroy-method属性指定的初始化方法");
96 }
97 }

2、接下来是演示BeanPostProcessor接口的方法，如下：
复制代码
1 package springBeanTest;
2
3 import org.springframework.beans.BeansException;
4 import org.springframework.beans.factory.config.BeanPostProcessor;
5
6 public class MyBeanPostProcessor implements BeanPostProcessor {
7
8 public MyBeanPostProcessor() {
9 super();
10 System.out.println("这是BeanPostProcessor实现类构造器！！");
11 // TODO Auto-generated constructor stub
12 }
13
14 @Override
15 public Object postProcessAfterInitialization(Object arg0, String arg1)
16 throws BeansException {
17 System.out
18 .println("BeanPostProcessor接口方法postProcessAfterInitialization对属性进行更改！");
19 return arg0;
20 }
21
22 @Override
23 public Object postProcessBeforeInitialization(Object arg0, String arg1)
24 throws BeansException {
25 System.out
26 .println("BeanPostProcessor接口方法postProcessBeforeInitialization对属性进行更改！");
27 return arg0;
28 }
29 }
复制代码
如上，BeanPostProcessor接口包括2个方法postProcessAfterInitialization和postProcessBeforeInitialization，这两个方法的第一个参数都是要处理的Bean对象，第二个参数都是Bean的name。返回值也都是要处理的Bean对象。这里要注意。
3、InstantiationAwareBeanPostProcessor 接口本质是BeanPostProcessor的子接口，一般我们继承Spring为其提供的适配器类InstantiationAwareBeanPostProcessor Adapter来使用它，如下：
复制代码
1 package springBeanTest;
2
3 import java.beans.PropertyDescriptor;
4
5 import org.springframework.beans.BeansException;
6 import org.springframework.beans.PropertyValues;
7 import org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessorAdapter;
8
9 public class MyInstantiationAwareBeanPostProcessor extends
10 InstantiationAwareBeanPostProcessorAdapter {
11
12 public MyInstantiationAwareBeanPostProcessor() {
13 super();
14 System.out
15 .println("这是InstantiationAwareBeanPostProcessorAdapter实现类构造器！！");
16 }
17
18 // 接口方法、实例化Bean之前调用
19 @Override
20 public Object postProcessBeforeInstantiation(Class beanClass,
21 String beanName) throws BeansException {
22 System.out
23 .println("InstantiationAwareBeanPostProcessor调用postProcessBeforeInstantiation方法");
24 return null;
25 }
26
27 //
