篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了生命周期-BeanPostProcessor-后置处理器相关的知识，希望对你有一定的参考价值。
通过实现BeanPostProcessor-后置处理器接口来实现bean在执行初始化方法（此时bean的属性已被赋值）前后的处理工作。
public class MyBeanPostProcessor implements BeanPostProcessor { public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { System.out.println("postProcessBeforeInitialization......"+ bean +"==>" + beanName); return bean; } public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { System.out.println("postProcessAfterInitialization...... "+ bean +"==>" + beanName); return bean; } }
