Beanpostprocessor and beanfactorypostprocessor

BeanFactoryPostProcessor

For all read bean Can be modified , I've got all of them before Bean Definition , Whether it's xml Or comments

@Component
public class BeanFactoryPostProcessorImp implements BeanFactoryPostProcessor {
    
    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
    
        System.out.println("factory");
        System.out.println(beanFactory.getBeanDefinition("simple").getBeanClassName());
    }
}

BeanPostProcessor

initializeBean In this method, the post processor is executed
stay bean Before initialization , It can be processed after initialization

@Component
public class BeanPostProcessorImp implements BeanPostProcessor {
    
    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
    
        System.out.println(" Before initialization ");
        return bean;
    }

    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
    
        System.out.println(" After the initialization ");
        return bean;
    }
}

Conclusion

BeanFactoryPostProcessor Order first
BeanPostProcessor Order after
