public interface BeanPostProcessor
```
Factory hook that allows for custom modification of new bean instances — for example, checking for marker interfaces or wrapping beans with proxies.
Typically, post-processors that populate beans via marker interfaces or the like will implement postProcessBeforeInitialization(java.lang.Object, java.lang.String), while post-processors that wrap beans with proxies will normally implement postProcessAfterInitialization(java.lang.Object, java.lang.String).
Registration
An ApplicationContext can autodetect BeanPostProcessor beans in its bean definitions and apply those post-processors to any beans subsequently created. A plain BeanFactory allows for programmatic registration of post-processors, applying them to all beans created through the bean factory.
Ordering
BeanPostProcessor beans that are autodetected in an ApplicationContext will be ordered according to PriorityOrdered and Ordered semantics. In contrast, BeanPostProcessor beans that are registered programmatically with a BeanFactory will be applied in the order of registration; any ordering semantics expressed through implementing the PriorityOrdered or Ordered interface will be ignored for programmatically registered post-processors. Furthermore, the @Order annotation is not taken into account for BeanPostProcessor beans.

`default Object`	`postProcessAfterInitialization(Object bean, String beanName)`	Apply this `BeanPostProcessor` to the given new bean instance after any bean initialization callbacks (like InitializingBean's `afterPropertiesSet` or a custom init-method).
`default Object`	`postProcessBeforeInitialization(Object bean, String beanName)`	Apply this `BeanPostProcessor` to the given new bean instance before any bean initialization callbacks (like InitializingBean's `afterPropertiesSet` or a custom init-method).

default Object postProcessBeforeInitialization(Object bean,
                                               String beanName)
                                        throws BeansException
```
    Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.
    The default implementation returns the given bean as-is.
    参数:
    bean - the new bean instance
    beanName - the name of the bean
    返回:
    the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
    抛出:
    BeansException - in case of errors

@Nullable
default Object postProcessAfterInitialization(Object bean,
                                              String beanName)
                                       throws BeansException
```
    Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.
    In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding bean instanceof FactoryBean checks.
    This callback will also be invoked after a short-circuiting triggered by a InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method, in contrast to all other BeanPostProcessor callbacks.
    The default implementation returns the given bean as-is.
    参数:
    bean - the new bean instance
    beanName - the name of the bean
    返回:
    the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
    抛出:
    BeansException - in case of errors
